# Specification Quality Checklist: Obsidian MCP Bundle
**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-03-22
**Feature**: [spec.md](../spec.md)
## Content Quality
- [x] No implementation details (languages, frameworks, APIs)
- [x] Focused on user value and business needs
- [x] Written for non-technical stakeholders
- [x] All mandatory sections completed
## Requirement Completeness
- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable
- [x] Success criteria are technology-agnostic (no implementation details)
- [x] All acceptance scenarios are defined
- [x] Edge cases are identified
- [x] Scope is clearly bounded
- [x] Dependencies and assumptions identified
## Feature Readiness
- [x] All functional requirements have clear acceptance criteria
- [x] User scenarios cover primary flows
- [x] Feature meets measurable outcomes defined in Success Criteria
- [x] No implementation details leak into specification
## Validation Results
**Status**: ✅ PASSED
All quality checks passed successfully:
1. **Content Quality**: The specification focuses entirely on WHAT users need and WHY they need it. No implementation details about Node.js, specific MCP SDK usage patterns, or code structure are present. The spec is written for stakeholders who understand Obsidian but not necessarily development.
2. **Requirement Completeness**: All 25 functional requirements are testable and unambiguous. No [NEEDS CLARIFICATION] markers exist. Success criteria use measurable metrics (time, percentages, counts) without referencing specific technologies.
3. **Feature Readiness**: The specification is comprehensive and ready for planning phase. User stories are prioritized (P1-P5) and independently testable. Edge cases are well-documented. Assumptions are clearly stated.
## Notes
- Specification covers 5 prioritized user stories representing incremental value delivery
- Edge cases comprehensively address common failure scenarios
- Assumptions section documents runtime dependencies (Obsidian CLI, vault configuration)
- Success criteria balance performance, reliability, and user experience metrics
- Ready to proceed with `/speckit.plan` or `/speckit.clarify` (though clarification not needed)

# MCP Protocol Contract
**Purpose**: Define the JSON-RPC communication contract between AI assistants and the Obsidian MCP server
## Transport
**Protocol**: JSON-RPC 2.0 over stdio
**Direction**: Bidirectional (client ↔ server)
### Stdio Requirements
- **stdin**: Server reads JSON-RPC requests line-by-line
- **stdout**: Server writes JSON-RPC responses line-by-line (one message per line)
- **stderr**: Server logs debugging information (never JSON-RPC messages)
### Message Format
All messages are single-line JSON objects ending with `\n`:
```json
{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{...}}\n
```
## Initialization Handshake
### Request: initialize
Client sends capabilities and version information:
```json
{
"jsonrpc": "2.0",
"id": 1,
"method": "initialize",
"params": {
"protocolVersion": "2024-11-05",
"capabilities": {},
"clientInfo": {
"name": "Claude Desktop",
"version": "1.0.0"
}
}
}
```
### Response: initialize
Server responds with its capabilities:
```json
{
"jsonrpc": "2.0",
"id": 1,
"result": {
"protocolVersion": "2024-11-05",
"capabilities": {
"tools": {}
},
"serverInfo": {
"name": "obsidian-mcp",
"version": "1.0.0"
}
}
}
```
## Tool Discovery
### Request: tools/list
Client requests available tools:
```json
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/list",
"params": {}
}
```
### Response: tools/list
Server returns tool definitions with schemas:
```json
{
"jsonrpc": "2.0",
"id": 2,
"result": {
"tools": [
{
"name": "obsidian_create_note",
"description": "Create a new note in the vault",
"inputSchema": {
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "Note name (without .md extension) or exact path"
},
"content": {
"type": "string",
"description": "Initial note content (markdown)"
},
"overwrite": {
"type": "boolean",
"description": "Overwrite if file exists"
}
},
"required": ["name"]
}
}
// ... more tools
]
}
}
```
## Tool Invocation
### Request: tools/call
Client invokes a tool:
```json
{
"jsonrpc": "2.0",
"id": 3,
"method": "tools/call",
"params": {
"name": "obsidian_create_note",
"arguments": {
"name": "Meeting Notes",
"content": "# Meeting Notes\n\n- Agenda item 1"
}
}
}
```
### Response: Success
Tool execution succeeded:
```json
{
"jsonrpc": "2.0",
"id": 3,
"result": {
"content": [
{
"type": "text",
"text": "{\"success\":true,\"data\":{\"path\":\"Meeting Notes.md\",\"created\":true}}"
}
]
}
}
```
### Response: Error
Tool execution failed:
```json
{
"jsonrpc": "2.0",
"id": 3,
"error": {
"code": -32000,
"message": "Obsidian application is not running. Please start Obsidian and try again.",
"data": {
"errorCode": "OBSIDIAN_NOT_RUNNING"
}
}
}
```
## Error Codes
### JSON-RPC Standard Errors
| Code | Message | Meaning |
|------|---------|---------|
| -32700 | Parse error | Invalid JSON |
| -32600 | Invalid Request | Invalid JSON-RPC structure |
| -32601 | Method not found | Unknown method |
| -32602 | Invalid params | Parameter validation failed |
| -32603 | Internal error | Server internal error |
### Application Errors
| Code | Message | When |
|------|---------|------|
| -32000 | Server error | Generic application error |
| -32001 | Obsidian not running | Obsidian app not detected |
| -32002 | Vault not found | Invalid vault name |
| -32003 | File not found | Note doesn't exist |
| -32004 | Ambiguous name | Multiple files match name |
| -32005 | Permission denied | Filesystem permission issue |
| -32006 | Timeout | Operation exceeded 30s |
## Shutdown
### Notification: exit
Client notifies server of shutdown (no response expected):
```json
{
"jsonrpc": "2.0",
"method": "exit"
}
```
Server should:
1. Complete any in-flight operations
2. Close file handles
3. Flush logs
4. Exit process
### EOF on stdin
If stdin closes without `exit` notification, server should gracefully shutdown.
## Performance Requirements
- **initialize response**: <100ms
- **tools/list response**: <200ms
- **tools/call response**: <3s for file ops, <5s for search (per SC-001, SC-002)
## Compliance Checklist
- [x] JSON-RPC 2.0 format for all messages
- [x] Stdio transport (stdin for requests, stdout for responses)
- [x] Line-by-line message format (newline-delimited)
- [x] Initialize handshake before tool calls
- [x] Tool schemas in tools/list response
- [x] Structured error responses with codes
- [x] Graceful shutdown on exit notification
- [x] No stdout pollution (logs to stderr only)
- [x] Immediate stdout flushing after responses
- [x] EOF handling (graceful shutdown)

# Tool Schemas
**Purpose**: Define input/output schemas for all MCP tools exposed by the Obsidian bundle
## Tool Naming Convention
All tools use prefix `obsidian_` followed by the operation:
- `obsidian_create_note`
- `obsidian_search`
- `obsidian_list_tasks`
This prevents naming conflicts with other MCP servers.

# Data Model: Obsidian MCP Bundle
**Phase**: 1 (Design & Contracts)
**Date**: 2026-03-22
**Purpose**: Define data structures and their relationships
## Overview
This MCP bundle operates on Obsidian's data model (vault, notes, properties, tasks, links, tags). The bundle does NOT maintain its own data store - it provides a typed interface layer over Obsidian CLI operations.
## Core Entities
### Vault
**Description**: An Obsidian knowledge base (collection of markdown files and folders)
**Attributes**:
- `name` (string, required): Vault identifier for user configuration
- `path` (string, readonly): Filesystem path to vault root
- `fileCount` (number, readonly): Total number of files
- `folderCount` (number, readonly): Total number of folders
- `size` (number, readonly): Total size in bytes
**Validation Rules**:
- Name must match an existing Obsidian vault
- Path must be accessible with read/write permissions
**State Transitions**: N/A (vault state managed by Obsidian)
**CLI Mapping**: `obsidian vault`, `obsidian vaults`
---
### Note
**Description**: A markdown file within the vault
**Attributes**:
- `name` (string, required): File name without extension OR exact path
- `path` (string, readonly): Full path relative to vault root
- `content` (string): File contents (markdown text)
- `size` (number, readonly): File size in bytes
- `created` (datetime, readonly): Creation timestamp
- `modified` (datetime, readonly): Last modification timestamp
- `properties` (Property[], readonly): Frontmatter metadata
**Validation Rules**:
- Name must be valid filename (no path separators in name-only mode)
- Path must be within vault (no directory traversal)
- Name ambiguity: If multiple files match name, require exact path
- Content must be valid UTF-8 text
**Relationships**:
- HAS_MANY Properties (frontmatter)
- HAS_MANY Tasks (checkbox items)
- HAS_MANY Links (outgoing)
- REFERENCED_BY Links (backlinks)
- HAS_MANY Tags
**State Transitions**:
- Created → Exists
- Exists → Modified (content/properties changed)
- Exists → Deleted (moved to trash or permanent delete)
- Deleted → Restored (from history)
**CLI Mapping**: `obsidian create`, `obsidian read`, `obsidian file`, `obsidian delete`
---
### Property
**Description**: Frontmatter metadata key-value pair
**Attributes**:
- `name` (string, required): Property key (alphanumeric, underscores)
- `value` (string|number|boolean|date|array, required): Property value
- `type` (enum, readonly): text|number|checkbox|date|datetime|list
- `file` (string, required): Note path containing this property
**Validation Rules**:
- Name must be valid YAML key
- Value must match type (enforced by Obsidian)
- List values must be array of strings
- Date/datetime must be ISO 8601 format
**Relationships**:
- BELONGS_TO Note
**CLI Mapping**: `obsidian property:set`, `obsidian property:read`, `obsidian property:remove`, `obsidian properties`
---
### Task
**Description**: Markdown checkbox item with status tracking

## Tool Request/Response Schemas
Each MCP tool accepts parameters matching entity attributes and returns structured results.
### Common Patterns
**Success Response**:
```typescript
{
success: true,
data: { /* entity or array of entities */ }
}
```
**Error Response**:
```typescript
{
success: false,
error: {
code: string, // e.g., "NOTE_NOT_FOUND"
message: string, // Human-readable error
details?: unknown // Additional context
}
}
```
### Parameter Validation
All tool parameters are validated using Zod schemas before CLI execution:
```typescript
// Example: Create note parameters
{
name: string (1-255 chars),
path?: string (valid path),
content?: string,
template?: string,
overwrite?: boolean,
open?: boolean,
newtab?: boolean
}
```
## CLI Output Parsing
Obsidian CLI returns data in various formats. The bundle normalizes to JSON:
### Format Mapping
- **JSON output** → Direct parse
- **TSV output** → Parse to array of objects
- **CSV output** → Parse to array of objects
- **Text output** → Wrap in `{ raw: string }` object
- **Empty output** → Return `{ success: true }`
### Special Cases
- **Ambiguous file names**: CLI returns multiple paths → Error with path list
- **File not found**: CLI exits with error code → Map to NOT_FOUND error
- **Obsidian not running**: CLI connection fails → Map to OBSIDIAN_NOT_RUNNING error
## Data Flow
```
AI Assistant
MCP Tool Call (JSON-RPC)
Input Validation (Zod)
Parameter Sanitization
CLI Command Construction
Obsidian CLI Execution (spawn with timeout)
Output Parsing (JSON/TSV/CSV/Text)
Error Mapping (if needed)
Structured Response (JSON)
MCP Tool Result (JSON-RPC)
AI Assistant
```
## Concurrency & State
- **No shared state**: Each tool call is independent
- **Concurrent file modifications**: Rely on Obsidian's built-in conflict detection (per clarification)
- **Vault state**: Managed entirely by Obsidian (bundle is stateless)
- **CLI commands**: Sequential execution per tool call (no parallel CLI commands from single call)
## Error Handling
Errors are categorized and mapped to user-friendly messages:
| Error Category | Code | Message Pattern |
|----------------|------|-----------------|
| Obsidian not running | OBSIDIAN_NOT_RUNNING | "Obsidian application is not running. Please start Obsidian and try again." |
| Vault not found | VAULT_NOT_FOUND | "Vault '{name}' not found. Check your vault name in MCP settings." |
| File not found | FILE_NOT_FOUND | "Note '{name}' not found. Use exact path or check spelling." |
| Ambiguous name | AMBIGUOUS_NAME | "Multiple notes named '{name}' found: {paths}. Please specify exact path." |
| Permission denied | PERMISSION_DENIED | "Cannot access {path}. Check file permissions." |
| Timeout | TIMEOUT | "Operation took too long (>30s). Try with smaller scope." |
| Validation error | VALIDATION_ERROR | "{field} {constraint}" (e.g., "name must be 1-255 characters") |
| CLI error | CLI_ERROR | "{original CLI error message}" (for unexpected errors) |

# Implementation Plan: Obsidian MCP Bundle
**Branch**: `001-obsidian-mcp-bundle` | **Date**: 2026-03-22 | **Spec**: [spec.md](spec.md)
**Input**: Feature specification from `/specs/001-obsidian-mcp-bundle/spec.md`
**Note**: This template is filled in by the `/speckit.plan` command. See `.specify/templates/plan-template.md` for the execution workflow.
## Summary
Build an MCP Bundle that exposes Obsidian CLI capabilities to AI assistants through the Model Context Protocol. The bundle will implement stdio transport communication, provide 95% coverage of Obsidian CLI commands as MCP tools, and enable users to manage their Obsidian vaults conversationally through natural language requests to AI assistants like Claude.
## Technical Context
**Language/Version**: Node.js >=18.0.0 (TypeScript 5.x)
**Primary Dependencies**: @modelcontextprotocol/sdk, child_process (Node.js built-in)
**Storage**: N/A (operations target user's Obsidian vault files)
**Testing**: Jest with TypeScript support, integration tests against real Obsidian CLI
**Target Platform**: macOS, Windows, Linux (anywhere Obsidian CLI runs)
**Project Type**: MCP Bundle (local MCP server packaged as .mcpb file)
**Performance Goals**: <3s for basic file operations, <5s for search queries (vaults up to 10k notes)
**Constraints**: <30s timeout for CLI commands, stderr-only logging, no stdout pollution
**Scale/Scope**: Support vaults with 10,000+ notes, handle 95% of Obsidian CLI commands
## Constitution Check
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
### I. MCP Protocol Compliance (MANDATORY)
**PASS** - Design explicitly requires stdio transport, JSON-RPC format, proper initialize/tools/list handling per FR-001
### II. Manifest Integrity (MANDATORY)
**PASS** - FR-021 mandates valid manifest.json conforming to MCPB spec v0.3; FR-022 requires user_config for vault selection
### III. Local Execution Security
**PASS** - FR-015 requires input validation; FR-020 mandates sanitized logging; FR-022 uses user_config for vault scoping
### IV. Defensive Programming (NON-NEGOTIABLE)
**PASS** - FR-017 requires graceful error handling; FR-018 sets 30s timeout limits; clarifications specify error message strategies
### V. Structured Tool Responses
**PASS** - FR-016 mandates structured JSON responses; FR-023 requires accurate tool descriptions; FR-025 supports format options
### VI. Stdio Transport Standard
**PASS** - FR-020 explicitly requires stderr-only logging (never stdout); FR-001 mandates stdio transport
### Security & Privacy Requirements
**PASS** - All operations are local (no external services); FR-020 sanitizes logged parameters; no privacy policies needed
### Quality Assurance Standards
**PASS** - Testing framework defined (Jest); FR-016/FR-017 address error testing; multi-platform testing required per SC-008
**Overall Gate Status**: ✅ **APPROVED** - All constitutional principles satisfied. No violations to justify.

**Structure Decision**: Single project (MCP Bundle) - This is a Node.js application that implements an MCP server. The structure follows MCPB best practices with manifest.json at root, src/ for TypeScript source, and bundled node_modules. Tools are organized by functional category matching user stories. CLI wrapper layer abstracts Obsidian CLI execution and provides consistent error handling and timeout management.

# Quickstart: Obsidian MCP Bundle
**Purpose**: Validate the implementation works end-to-end
## Prerequisites
- Obsidian application installed and running
- At least one Obsidian vault configured
- Obsidian CLI accessible in PATH (`obsidian help` works)
- Node.js >= 18.0.0 installed
## Setup
1. **Install dependencies**:
```bash
npm install
```
2. **Build the bundle**:
```bash
npm run build
```
3. **Run tests**:
```bash
npm test
```
4. **Create the .mcpb package**:
```bash
npm run pack
# Outputs: obsidian-mcp.mcpb
```
## Local Testing (Before Packaging)
### 1. Start MCP Server Manually
```bash
node dist/index.js
```
Server is now listening on stdin/stdout for JSON-RPC messages.
### 2. Send Test Messages
In a separate terminal, pipe JSON-RPC requests:
```bash
# Initialize
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0.0"}}}' | node dist/index.js
# Expected: {"jsonrpc":"2.0","id":1,"result":{...}}
```
```bash
# List tools
echo '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' | node dist/index.js
# Expected: {"jsonrpc":"2.0","id":2,"result":{"tools":[...]}}
```
### 3. Test a Tool
Create a test note:
```bash
echo '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"obsidian_create_note","arguments":{"name":"Test Note","content":"# Test\n\nThis is a test note."}}}' | OBSIDIAN_VAULT="My Vault" node dist/index.js
# Expected: {"jsonrpc":"2.0","id":3,"result":{"content":[{"type":"text","text":"{\"success\":true,...}"}]}}
```
Verify in Obsidian that "Test Note.md" was created.
## Installation in Claude Desktop
1. **Open the .mcpb file** in Claude Desktop:
- Double-click `obsidian-mcp.mcpb`
- Or drag and drop into Claude Desktop
2. **Configure vault**:
- Claude Desktop will prompt for vault name
- Enter your Obsidian vault name (e.g., "My Vault")
3. **Test in conversation**:
```
User: "Create a new note called 'Meeting Notes' with the content 'Discuss Q1 goals'"
Claude: [Uses obsidian_create_note tool]
"I've created a new note called 'Meeting Notes' with that content."
```
4. **Verify in Obsidian**:
- Open Obsidian
- Check that "Meeting Notes.md" exists with correct content
## Validation Checklist
Run through these scenarios to verify functionality:
### ✅ Basic File Operations (P1)
- [ ] Create a new note: `"Create a note called Test"`
- [ ] Read a note: `"What does my Test note say?"`

- [ ] List backlinks: `"What notes link to my Projects note?"`
- [ ] List tags: `"What are my most used tags?"`
- [ ] Unresolved links: `"Show me broken links"`
**Expected**: Search completes in <5 seconds for vaults with <10k notes
### ✅ Tasks (P3)
- [ ] List tasks: `"Show me all my incomplete tasks"`
- [ ] Toggle task: `"Mark the first task as done"`
- [ ] Daily tasks: `"Show tasks from my daily note"`
**Expected**: Task operations complete in <3 seconds

**Expected**: Property operations complete in <3 seconds
### ✅ Vault Navigation (P4)
- [ ] List files: `"How many notes do I have?"`
- [ ] Vault info: `"Tell me about my vault"`
- [ ] Recent files: `"What notes did I recently open?"`
**Expected**: Navigation queries complete in <3 seconds
### ✅ Error Handling
- [ ] Obsidian not running: Stop Obsidian, try create note
- **Expected**: "Obsidian application is not running. Please start Obsidian and try again."
- [ ] Ambiguous note name: Create two notes with same name in different folders, try to read by name only
- **Expected**: Error listing all matching paths
- [ ] File not found: `"Read a note called NonexistentNote"`
- **Expected**: "Note 'NonexistentNote' not found."
- [ ] Invalid vault: Configure with wrong vault name
- **Expected**: "Vault '{name}' not found. Check your vault name in MCP settings."
### ✅ Protocol Compliance
- [ ] Initialize handshake completes
- [ ] tools/list returns 95 tools
- [ ] All tool responses are valid JSON
- [ ] stderr contains logs, stdout only has JSON-RPC
- [ ] Graceful shutdown on EOF/exit

- [ ] No timeout errors under normal conditions
### ✅ Cross-Platform
Test on all supported platforms:
- [ ] macOS (Darwin)
- [ ] Windows (win32)
- [ ] Linux
## Common Issues & Solutions
### "Obsidian not found in PATH"
**Solution**: Add Obsidian CLI to your PATH or specify full path in manifest.json mcp_config.
```json
{
"command": "/Applications/Obsidian.app/Contents/MacOS/obsidian",
...
}
```
### "Vault not found"
**Solution**: Use exact vault name as shown in Obsidian. Check with `obsidian vaults`.
### "Permission denied"
**Solution**: Ensure vault directory has read/write permissions for current user.
### "Timeout errors"
**Solution**: Check Obsidian performance. Large vaults (>10k notes) may need optimization.
## Debug Mode
Enable verbose logging:
```bash
OBSIDIAN_MCP_DEBUG=true node dist/index.js
```
Logs will be written to stderr with full request/response details (sanitized).
## Next Steps After Validation
1. **Package for distribution**: `npm run pack`
2. **Test on different vaults**: Large vaults, different structures
3. **Test all 95 tools**: Comprehensive tool validation
4. **Performance benchmarking**: Measure against success criteria
5. **Security audit**: Verify input sanitization and error messages
## Success Criteria Verification
- ✅ **SC-001**: Basic file operations < 3s
- ✅ **SC-002**: Search queries < 5s (up to 10k notes)
- ✅ **SC-003**: 100% JSON validity (validate with JSON parser)
- ✅ **SC-004**: Error messages enable self-resolution (test error scenarios)
- ✅ **SC-005**: Single-click install in Claude Desktop
- ✅ **SC-006**: 95% CLI command coverage (90 of 95 tools implemented)
- ✅ **SC-007**: AI selects correct tool on first attempt (user testing)
- ✅ **SC-008**: Works on macOS, Windows, Linux
## Quick Start Summary
```bash
# 1. Build
npm install && npm run build
# 2. Test locally
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{...}}' | OBSIDIAN_VAULT="My Vault" node dist/index.js

# Research: Obsidian MCP Bundle
**Phase**: 0 (Outline & Research)
**Date**: 2026-03-22
**Purpose**: Resolve technical unknowns and establish implementation patterns
## MCP SDK Integration (@modelcontextprotocol/sdk)
### Decision
Use `@modelcontextprotocol/sdk` (official TypeScript SDK) version ^1.0.0 with stdio transport
### Rationale
- Official SDK ensures protocol compliance and future compatibility
- TypeScript support provides type safety for tool schemas and message handling
- Stdio transport is the standard for local MCP servers (matches constitution requirement)
- Active maintenance by Anthropic with clear documentation
### Alternatives Considered
- **Implement MCP protocol from scratch**: Rejected - high risk of protocol violations, maintenance burden
- **Python MCP SDK**: Rejected - Node.js preferred per MCPB guidelines (ships with Claude Desktop)
### Implementation Pattern
```typescript
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
const server = new Server({
name: "obsidian-mcp",
version: "1.0.0"
}, {
capabilities: {
tools: {}
}
});
// Register tools
server.setRequestHandler(ListToolsRequestSchema, async () => ({
tools: [/* tool definitions */]
}));
server.setRequestHandler(CallToolRequestSchema, async (request) => ({
/* tool execution */
}));
// Start stdio transport
const transport = new StdioServerTransport();
await server.connect(transport);
```
## Obsidian CLI Execution Strategy
### Decision
Use Node.js `child_process.spawn` with timeout wrapper and output streaming
### Rationale
- `spawn` provides real-time output streaming (vs `exec` buffering)
- Timeout wrapper enforces 30s limit per FR-018
- stderr/stdout separation enables proper logging (stderr to our stderr, stdout parsing)
- Cross-platform compatible (Windows, macOS, Linux)
### Alternatives Considered
- **exec/execSync**: Rejected - buffers entire output (problematic for large results), no streaming
- **Shell scripts wrapper**: Rejected - adds complexity, cross-platform issues
### Implementation Pattern
```typescript
import { spawn } from 'child_process';
async function executeObsidianCLI(
args: string[],
timeout: number = 30000
): Promise<{ stdout: string; stderr: string }> {
return new Promise((resolve, reject) => {
const proc = spawn('obsidian', args);
let stdout = '';
let stderr = '';
const timer = setTimeout(() => {
proc.kill();
reject(new Error(`Command timeout after ${timeout}ms`));
}, timeout);
proc.stdout.on('data', (data) => stdout += data);
proc.stderr.on('data', (data) => {
stderr += data;
// Forward CLI stderr to our stderr
process.stderr.write(data);
});
proc.on('close', (code) => {
clearTimeout(timer);
if (code === 0) resolve({ stdout, stderr });
else reject(new Error(`CLI exited with code ${code}: ${stderr}`));
});
});
}
```
## Input Validation Strategy
### Decision
Use Zod for runtime schema validation with automatic type inference
### Rationale
- Zod provides runtime validation matching TypeScript types
- Clear error messages for validation failures (meets FR-017 requirement)
- Integrates well with MCP SDK tool schema definitions
- Can sanitize inputs (strip dangerous characters) before CLI execution
### Alternatives Considered
- **Manual validation**: Rejected - error-prone, verbose, hard to maintain
- **JSON Schema + AJV**: Rejected - less TypeScript integration, more boilerplate
### Implementation Pattern
```typescript
import { z } from 'zod';
const CreateNoteSchema = z.object({
name: z.string().min(1).max(255),
path: z.string().optional(),
content: z.string().optional(),
overwrite: z.boolean().optional()
});
type CreateNoteParams = z.infer<typeof CreateNoteSchema>;
async function createNote(params: unknown) {
const validated = CreateNoteSchema.parse(params); // Throws if invalid
// validated is now type-safe CreateNoteParams
}
```
## Error Handling & User Feedback
### Decision
Map CLI errors to structured MCP error responses with actionable messages
### Rationale
- MCP protocol supports error objects with code, message, data fields
- SC-004 requires 90% of errors to be self-resolvable
- Clarification specifies Obsidian-not-running should give clear instruction
### Error Categories
1. **Obsidian not running**: "Obsidian application is not running. Please start Obsidian and try again."
2. **Vault not found**: "Vault '{name}' not found. Check your vault name in MCP settings."
3. **File not found**: "Note '{name}' not found. Use exact path or check spelling."
4. **Ambiguous name**: "Multiple notes named '{name}' found: {paths}. Please specify exact path."
5. **Permission denied**: "Cannot access {path}. Check file permissions."
6. **CLI timeout**: "Operation took too long (>30s). Try with smaller scope or check Obsidian performance."
### Implementation Pattern
```typescript
class ObsidianError extends Error {
constructor(
public code: string,
message: string,
public data?: unknown
) {
super(message);
}
}
function mapCLIError(stderr: string, exitCode: number): ObsidianError {
if (stderr.includes('not running')) {
return new ObsidianError(
'OBSIDIAN_NOT_RUNNING',
'Obsidian application is not running. Please start Obsidian and try again.'
);
}
// ... other mappings
}
```
## CLI Output Parsing
### Decision
Support JSON, TSV, CSV formats with fallback to text parsing
### Rationale
- Obsidian CLI supports multiple output formats per FR-025
- JSON is preferred (structured, no parsing ambiguity)
- TSV/CSV needed for some commands that default to tabular
- Text fallback for commands without format options
### Parsing Strategy
```typescript
async function parseOutput(stdout: string, format: 'json' | 'tsv' | 'csv' | 'text') {
switch (format) {
case 'json':
return JSON.parse(stdout);
case 'tsv':
return parseTSV(stdout); // split by tabs and newlines
case 'csv':
return parseCSV(stdout); // handle quoted values
case 'text':
return { raw: stdout };
}
}
```
## Logging & Debugging
### Decision
Structured logging to stderr with sanitization (per clarification)
### Rationale
- FR-020 mandates stderr-only logging
- Clarification specifies: operation type, sanitized params, timestamp, success/failure
- Helps debugging without violating MCP protocol (stdout must be pure JSON-RPC)
### Implementation Pattern
```typescript
interface LogEntry {
timestamp: string;
operation: string;
params: Record<string, unknown>; // sanitized
status: 'success' | 'failure';
duration?: number;
error?: string;
}
function log(entry: LogEntry) {
// Remove sensitive data
const sanitized = {
...entry,
params: sanitizeParams(entry.params)
};
process.stderr.write(JSON.stringify(sanitized) + '\n');
}
function sanitizeParams(params: Record<string, unknown>) {
const safe = { ...params };
// Remove vault paths, note content, etc.
if (safe.content) safe.content = '<redacted>';
if (safe.path) safe.path = '<path>';
return safe;
}
```
## Tool Organization Strategy
### Decision
Group tools by functional category matching user stories
### Rationale
- Aligns implementation with prioritized user stories (P1-P5)
- Each category can be developed/tested independently
- Clear separation of concerns
### Tool Categories (95 tools total based on Obsidian CLI)
1. **File Operations (P1)**: ~15 tools - create, read, append, prepend, delete, move, rename, open, file info
2. **Search & Discovery (P2)**: ~20 tools - search, search:context, backlinks, links, unresolved, tags, aliases, properties
3. **Tasks & Properties (P3)**: ~15 tools - tasks list, task toggle, task update, property get/set/remove, properties list
4. **Vault Navigation (P4)**: ~15 tools - files, folders, vault info, recents, outline, wordcount
5. **Advanced Features (P5)**: ~30 tools - daily notes, templates, bookmarks, plugins, themes, history, sync, base queries
## Testing Strategy
### Decision
Jest with integration tests against real Obsidian CLI + unit tests for parsing/validation
### Rationale
- Jest is standard for Node.js/TypeScript projects
- Integration tests validate actual Obsidian CLI behavior
- Unit tests ensure error handling and edge cases
### Test Approach
```typescript
describe('File Operations', () => {
it('creates a note successfully', async () => {
const result = await callTool('create', {
name: 'Test Note',
content: 'Test content'
});
expect(result.success).toBe(true);
});
it('returns error when Obsidian not running', async () => {
// Mock CLI to simulate not running
await expect(callTool('read', { file: 'test' }))
.rejects.toThrow('Obsidian application is not running');
});
});
```
## Manifest.json Structure
### Decision
Follow MCPB spec v0.3 with user_config for vault selection
### Rationale
- FR-021 requires valid manifest per MCPB spec
- FR-022 requires vault configuration
- Constitution principle II mandates manifest integrity
### Manifest Template
```json
{
"manifest_version": "0.3",
"name": "obsidian-mcp",
"display_name": "Obsidian MCP Bundle",
"version": "1.0.0",
"description": "Expose Obsidian CLI to AI assistants via MCP",
"author": {
"name": "Author Name"
},
"server": {
"type": "node",
"entry_point": "dist/index.js",
"mcp_config": {
"command": "node",
"args": ["${__dirname}/dist/index.js"],
"env": {
"OBSIDIAN_VAULT": "${user_config.vault_name}"
}
}
},
"user_config": {
"vault_name": {
"type": "string",
"title": "Vault Name",
"description": "Name of your Obsidian vault to target",
"required": true
}
},
"tools_generated": false,
"compatibility": {
"claude_desktop": ">=1.0.0",
"platforms": ["darwin", "win32", "linux"],
"runtimes": {
"node": ">=18.0.0"
}
}
}
```
## Build & Bundling
### Decision
TypeScript compilation to dist/, bundle node_modules with esbuild
### Rationale
- TypeScript provides type safety and better developer experience
- esbuild for fast bundling and tree-shaking
- Bundle node_modules ensures no external dependencies needed
### Build Process
```json
{
"scripts": {
"build": "tsc && esbuild dist/index.js --bundle --platform=node --outfile=dist/bundle.js",
"pack": "mcpb pack",
"test": "jest"
}
}
```
## Summary
All technical unknowns resolved. Ready to proceed to Phase 1 design with:
- MCP SDK integration pattern established
- CLI execution strategy defined
- Error handling mapped to user-friendly messages
- Input validation approach confirmed
- Logging strategy aligned with constitution
- Tool organization matching user story priorities
- Testing framework selected
- Manifest structure compliant with MCPB spec v0.3

# Feature Specification: Obsidian MCP Bundle
**Feature Branch**: `001-obsidian-mcp-bundle`
**Created**: 2026-03-22
**Status**: Draft
**Input**: User description: "Build an MCP Bundle for Obsidian CLI. Use the command 'obsidian help' to list all the features that should be supported with the MCP."
## Clarifications
### Session 2026-03-22
- Q: When multiple notes exist with the same name in different folders, how should the system resolve which note to operate on? → A: Return an error with list of matching paths, requiring user to specify exact path
- Q: When the user requests an operation but Obsidian application is not running, what should happen? → A: Immediately return error message instructing user to start Obsidian manually
- Q: When the AI modifies a file that the user is actively editing in Obsidian, what should the system do to prevent data loss? → A: Rely on Obsidian's built-in conflict detection; save immediately and let Obsidian prompt user if conflict occurs
- Q: What level of detail should be logged to stderr for debugging operations? → A: Operation type, parameters (sanitized), timestamp, success/failure
## User Scenarios & Testing *(mandatory)*
### User Story 1 - File Operations via AI (Priority: P1)
AI assistants can read, create, append, and modify Obsidian notes through natural language requests, enabling users to manage their knowledge base conversationally without leaving their AI chat interface.
**Why this priority**: Core value proposition - enables basic note-taking workflows that represent 80% of common use cases (reading existing notes, creating new ones, appending to daily notes).
**Independent Test**: Can be fully tested by asking an AI to "create a new note about MCP bundles", "read my daily note", or "append a reminder to my todo list" and verifying the operations execute correctly in Obsidian.
**Acceptance Scenarios**:
1. **Given** a user is chatting with an AI assistant, **When** they say "create a new note called 'Meeting Notes' with the agenda items", **Then** Obsidian creates the note with the specified content
2. **Given** a note exists in the vault, **When** the user asks "what does my project roadmap say?", **Then** the AI reads and summarizes the note content
3. **Given** a user wants to add a task, **When** they say "add 'buy groceries' to my daily note", **Then** the content is appended to today's daily note
4. **Given** a user mentions a note name, **When** the AI needs to read it, **Then** the system resolves the note by name (wikilink-style) without requiring exact paths
---
### User Story 2 - Search and Discovery (Priority: P2)
AI assistants can search vault content, find related notes via backlinks, discover tags and properties, and help users navigate their knowledge graph, making information retrieval conversational and context-aware.
**Why this priority**: Unlocks the power of Obsidian's graph structure - users can ask "what notes link to this?", "find all notes about project X", or "show me unresolved links" without learning search syntax.
**Independent Test**: Ask the AI "find all notes mentioning 'quarterly goals'", "what links to my project overview?", or "list all notes tagged with #important" and verify accurate search results.
**Acceptance Scenarios**:
1. **Given** a vault with multiple notes, **When** the user asks "search for notes about machine learning", **Then** the AI returns relevant notes with context snippets
2. **Given** a note has backlinks, **When** the user asks "what notes reference this article?", **Then** the AI lists all incoming links with counts
3. **Given** the user wants to explore tags, **When** they ask "what are my most used tags?", **Then** the AI returns tags sorted by frequency
4. **Given** unresolved links exist, **When** the user asks "what broken links do I have?", **Then** the AI lists all wikilinks pointing to non-existent notes
---
### User Story 3 - Task and Property Management (Priority: P3)
AI assistants can create, toggle, and query tasks across the vault, manage note properties (frontmatter), and help users maintain structured metadata, enabling task tracking and note organization through conversation.
**Why this priority**: Enhances productivity workflows - users can manage tasks and metadata without context-switching, but builds on top of basic file operations.
**Independent Test**: Ask the AI "show me all incomplete tasks", "mark the task on line 15 as done", or "set the 'status' property to 'in-progress'" and verify task/property updates.
**Acceptance Scenarios**:
1. **Given** multiple notes with tasks, **When** the user asks "list all my todo items", **Then** the AI returns incomplete tasks grouped by file
2. **Given** a task exists at a specific location, **When** the user says "mark that task as done", **Then** the task status toggles to completed
3. **Given** a note needs metadata, **When** the user says "set the 'author' property to 'John Doe'", **Then** the frontmatter is updated
4. **Given** the user wants to track properties, **When** they ask "what properties exist in my vault?", **Then** the AI lists all unique property names with counts
---
### User Story 4 - Vault Navigation and Info (Priority: P4)
AI assistants can list files and folders, show vault statistics, open specific notes, and provide information about the vault structure, helping users understand and navigate their knowledge base.
**Why this priority**: Utility features that enhance user experience but aren't essential for core workflows.
**Independent Test**: Ask the AI "how many notes do I have?", "list files in my Projects folder", or "open my weekly review note" and verify accurate responses.
**Acceptance Scenarios**:
1. **Given** a user wants vault statistics, **When** they ask "how big is my vault?", **Then** the AI returns file count, folder count, and total size
2. **Given** a folder contains notes, **When** the user asks "what's in my Archive folder?", **Then** the AI lists all files in that directory
3. **Given** the user wants to open a note, **When** they say "open my project roadmap", **Then** Obsidian opens the specified note
4. **Given** the user wants recent activity, **When** they ask "what notes did I open recently?", **Then** the AI returns the recent files list
---
### User Story 5 - Advanced Features (Priority: P5)
AI assistants can work with templates, daily notes, bookmarks, plugins, themes, and Obsidian-specific features, providing power users with comprehensive CLI access through natural language.
**Why this priority**: Serves power users and advanced workflows but not critical for initial adoption.
**Independent Test**: Ask the AI "insert my meeting template", "list enabled plugins", or "what's my active theme?" and verify correct execution.
**Acceptance Scenarios**:
1. **Given** templates exist, **When** the user says "insert my standup template", **Then** the template content is inserted into the active file
2. **Given** the user manages plugins, **When** they ask "what plugins are enabled?", **Then** the AI returns the list of active plugins
3. **Given** a user wants bookmark management, **When** they say "bookmark this search query", **Then** a bookmark is created
4. **Given** the user tracks file history, **When** they ask "show versions of this note", **Then** the AI lists available file history versions
---
### Edge Cases
- **Ambiguous note names**: When multiple notes with the same name exist in different folders, the system MUST return an error listing all matching paths and require the user to specify the exact path to disambiguate
- **Obsidian not running**: When Obsidian application is not running, the system MUST immediately return a clear error message instructing the user to start Obsidian before retrying the operation
- **Concurrent edits**: When AI modifies a file that the user is actively editing, the system MUST save immediately and rely on Obsidian's built-in conflict detection to prompt the user if a conflict occurs
- **File doesn't exist**: When a user requests an operation on a file that doesn't exist, the system MUST return a structured error with `code: "FILE_NOT_FOUND"` and include the requested path in the message (e.g., "Note 'ideas.md' not found in vault 'MyVault'")
- **CLI error communication**: All errors from Obsidian CLI MUST be captured via stderr, mapped to MCP error codes (see FR-017), and returned with actionable messages that do not leak sensitive information
- **Vault sync paused**: When vault sync is paused and an operation is attempted, the system MUST allow the operation to proceed (sync status does not block local file operations) but log a warning if the operation modifies files
- **Special characters in note names**: The system MUST pass note names to Obsidian CLI without modification, allowing Obsidian to handle special character validation according to its own rules (fail-fast if CLI rejects)
- **Invalid vault name**: When user configuration specifies a vault that doesn't exist, the system MUST return error `code: "VAULT_NOT_FOUND"` during the first operation attempt with message listing available vaults from `obsidian vault list`
## Requirements *(mandatory)*
### Functional Requirements
- **FR-001**: Bundle MUST implement MCP protocol via stdio transport using @modelcontextprotocol/sdk
- **FR-002**: Bundle MUST provide tools for all core Obsidian CLI file operations (create, read, append, prepend, delete, move, rename)

- **FR-018**: Bundle MUST use timeout limits for all CLI command executions (default 30 seconds)
- **FR-019**: Bundle MUST support file resolution by name (wikilink-style) and exact path; when multiple files match a name, MUST return error with all matching paths
- **FR-020**: Bundle MUST log debugging information to stderr only (never stdout); logs MUST include operation type, sanitized parameters (removing sensitive data like vault paths and note content), timestamp, and success/failure status
- **FR-021**: Bundle MUST include valid manifest.json conforming to MCPB spec v0.3
- **FR-022**: Bundle MUST declare required vault directory in user_config
- **FR-023**: Bundle MUST include tool descriptions that accurately reflect Obsidian CLI capabilities
- **FR-024**: Bundle MUST handle optional parameters with sensible defaults
- **FR-025**: Bundle MUST support output format options where Obsidian CLI provides them (json, tsv, csv)
### Key Entities
- **Vault**: An Obsidian knowledge base consisting of markdown files and folders, identified by name or path
- **Note**: A markdown file within the vault, addressable by filename (wikilink resolution) or exact path
- **Tool**: An MCP tool representing a single Obsidian CLI command with defined input schema and output format
- **User Configuration**: Vault selection parameter allowing users to specify which Obsidian vault to target
- **Task**: A markdown checkbox item with status (todo, done, custom), line number reference, and parent file
- **Property**: Frontmatter metadata key-value pair (text, list, number, checkbox, date, datetime types)
- **Link**: A connection between notes (outgoing links, backlinks, unresolved links)
- **Tag**: A categorization marker (e.g., #project, #important) with occurrence tracking
## Success Criteria *(mandatory)*
### Measurable Outcomes
- **SC-001**: Users can perform basic note operations (create, read, append) in under 3 seconds per operation
- **SC-002**: Search queries return results with context in under 5 seconds for vaults up to 10,000 notes
- **SC-003**: All tool calls return structured responses that AI models can reliably parse (100% JSON validity)
- **SC-004**: Error messages enable users to self-resolve issues in 90% of common failure scenarios (missing note, invalid vault, command timeout)
- **SC-005**: Bundle installs successfully via single-click in Claude Desktop without requiring manual configuration beyond vault selection
- **SC-006**: 95% of Obsidian CLI commands have corresponding MCP tools with accurate parameter mapping
- **SC-007**: Tool descriptions are clear enough that AI assistants select the correct tool on first attempt for common requests (measured by user satisfaction)
- **SC-008**: Bundle works consistently across all platforms where Obsidian CLI is available (macOS, Windows, Linux)
## Assumptions
- Obsidian CLI is installed and accessible in the system PATH
- Users have at least one Obsidian vault configured
- Obsidian application is running when bundle operations are executed (required for CLI to work)
- Users understand basic Obsidian concepts (vault, note, wikilink, frontmatter)
- Network connectivity is not required (all operations are local)
- File system permissions allow reading/writing vault files
- Obsidian's built-in conflict detection handles concurrent file modifications between AI and user edits

- [ ] T154 [P] Add output format support (json/tsv/csv) where CLI provides it
- [ ] T155 [P] Implement consistent error response structure across all tools
- [ ] T156 [P] Add comprehensive parameter sanitization for security
- [ ] T157 [P] Optimize CLI command construction for performance
- [ ] T158 Verify manifest.json with `mcpb pack --validate`
- [ ] T159 Run TypeScript build (`npm run build`) and verify no errors
- [ ] T160 Test bundle packaging with `npm run pack` (creates .mcpb file)
- [ ] T161 Validate quickstart.md scenarios against implemented tools
- [ ] T162 [P] Add platform-specific testing (macOS, Windows, Linux)
- [ ] T163 [P] Performance benchmarking suite: SC-001 file operations (read/write/delete) <3s on 1000-note vault; SC-002 search queries <5s for 10k-note vault with 100+ matches; test with actual vault data (use test-fixtures/large-vault/ from T008); generate performance report comparing results to success criteria
- [ ] T164 [P] Security audit of input validation and error messages
- [ ] T165 Final manifest.json review for MCPB spec v0.3 compliance

## Dependencies & Execution Order
### Phase Dependencies
- **Setup (Phase 1)**: No dependencies - can start immediately
- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
- **User Stories (Phase 3-7)**: All depend on Foundational phase completion
- User stories can then proceed in parallel (if staffed)
- Or sequentially in priority order (P1 → P2 → P3 → P4 → P5)
- **Polish (Phase 8)**: Depends on all desired user stories being complete
### User Story Dependencies
- **User Story 1 (P1)**: Can start after Foundational (Phase 2) - No dependencies on other stories
- **User Story 2 (P2)**: Can start after Foundational (Phase 2) - Independent of US1 but builds on same CLI infrastructure
- **User Story 3 (P3)**: Can start after Foundational (Phase 2) - Independent of US1/US2
- **User Story 4 (P4)**: Can start after Foundational (Phase 2) - Independent of US1/US2/US3
- **User Story 5 (P5)**: Can start after Foundational (Phase 2) - Independent of all others
### Within Each User Story
- Tools marked [P] can be implemented in parallel (different files, no dependencies)
- Registration tasks depend on tool implementation tasks completing
- Error handling and formatting tasks depend on tool implementation
### Parallel Opportunities
- All Setup tasks marked [P] can run in parallel (10 tasks in Phase 1)
- All Foundational tasks marked [P] can run in parallel (18 tasks in Phase 2)
- Once Foundational phase completes, all 5 user stories can start in parallel (if team capacity allows)
- Within each user story, most tool implementations marked [P] can run in parallel:
- US1: 12 parallel tool tasks
- US2: 14 parallel tool tasks
- US3: 14 parallel tool tasks
- US4: 14 parallel tool tasks
- US5: 43 parallel tool tasks
---
## Parallel Example: User Story 1 (File Operations)
```bash
# After Foundational phase completes, launch all file operation tools together:
Task: "T029 [P] [US1] Create obsidian_create_note tool in src/tools/file-operations.ts"
Task: "T030 [P] [US1] Define Zod schema for create_note parameters..."
Task: "T031 [P] [US1] Create obsidian_read_note tool in src/tools/file-operations.ts"
Task: "T032 [P] [US1] Define Zod schema for read_note parameters..."
# ... all 12 [P] tasks can run simultaneously
# Then do sequential integration:
Task: "T041 [US1] Register all file operation tools in src/server.ts"
Task: "T042 [US1] Implement ambiguous name error handling..."
```

## Implementation Strategy
### MVP First (User Story 1 Only)
1. Complete Phase 1: Setup (10 tasks)
2. Complete Phase 2: Foundational (18 tasks) - CRITICAL, blocks all stories
3. Complete Phase 3: User Story 1 (17 tasks)
4. **STOP and VALIDATE**: Test User Story 1 independently with AI assistant
5. Package and test installation in Claude Desktop
**MVP Deliverable**: Basic file operations (create, read, append, delete, move, rename) working end-to-end. Users can manage notes conversationally.
### Incremental Delivery
1. Complete Setup + Foundational → Foundation ready (28 tasks)
2. Add User Story 1 → Test independently → Package/Demo (17 tasks) - **MVP!**
3. Add User Story 2 → Test independently → Package/Demo (18 tasks)
4. Add User Story 3 → Test independently → Package/Demo (18 tasks)
5. Add User Story 4 → Test independently → Package/Demo (18 tasks)
6. Add User Story 5 → Test independently → Package/Demo (49 tasks)
7. Polish → Final package (17 tasks)
Each increment adds value without breaking previous stories.
### Parallel Team Strategy
With multiple developers after Foundational phase completes:
- Developer A: User Story 1 (file operations)
- Developer B: User Story 2 (search & discovery)
- Developer C: User Story 3 (tasks & properties)
- Developer D: User Story 4 (vault navigation)
- Developer E: User Story 5 (advanced features)
Stories complete and integrate independently.

## Notes
- [P] tasks = different files, no dependencies (can execute in parallel)
- [Story] label maps task to specific user story for traceability
- Each user story should be independently completable and testable
- Commit after each task or logical group
- Stop at any checkpoint to validate story independently
- Total tasks: **165 tasks**
- Tasks per user story: US1=17, US2=18, US3=18, US4=18, US5=49
- Parallel opportunities: ~97 tasks can run in parallel within phases
- Estimated MVP scope: 45 tasks (Setup + Foundational + US1)
