Problem

The MCP tool search_documents returns an error when called:

{"error":"BadRequestError","message":"Invalid integer for parameter: id","code":"BAD_REQUEST"}

Test Call:

mcp__plugin_claude-mem_mcp-search__search_documents({
  query: "React hooks",
  limit: 5
})

Analysis

The error suggests a routing issue where the backend is trying to parse query or another string parameter as an integer id. This could indicate:

The route is matching a different endpoint (e.g., /api/search/:id)
The search_documents endpoint isn't properly registered
Parameter parsing issue in the route handler

Expected Behavior

The endpoint should search the documents table for cached documentation and return matching results.
