# 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?"`
|
||||
- [ ] Append to a note: `"Add 'new line' to Test note"`
|
||||
- [ ] Delete a note: `"Delete the Test note"`
|
||||
|
||||
**Expected**: All operations complete in <3 seconds
|
||||
|
||||
### ✅ Search & Discovery (P2)
|
||||
|
||||
- [ ] Search vault: `"Find all notes mentioning 'project'"`
|
||||
- [ ] List backlinks: `"What notes link to my Projects note?"`
|
||||

|
||||
**Expected**: Navigation queries complete in <3 seconds
|
||||
|
||||
### ✅ Error Handling
|
||||
|

|
||||
- **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
|
||||
|
||||
### ✅ Performance

||||
- [ ] File operations: <3s (SC-001)
|
||||
- [ ] Search operations: <5s for 10k notes (SC-002)
|
||||

|
||||
|
||||
### ✅ 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
|
||||
|
||||
