Issue: The registerTool method was receiving description and inputSchema
parameters but marking them as unused (_description, _inputSchema) and
not storing them with the handler. This caused tools/list to return
tools without their description and inputSchema properties.
Fix: Remove underscore prefixes and explicitly set these properties on
the handler object before storing it in the tools Map.
Now tools/list will properly return:
- name: Tool name
- description: Tool description (from registerTool call)
- inputSchema: Tool input schema (from registerTool call)
This ensures MCP clients can see proper tool documentation and schemas.
Files changed:
- src/server.ts: Fixed registerTool to preserve metadata
Build: ✅ 0 errors
