Error when attempting to use MCP search tool from Claude

[sirknigget]

I followed the README installation steps and then attempted to use it with Claude Code.

I am getting this, seems like some extension needs to be installed:

● cocoindex-code - search (MCP)(query: "keeping track of codebase map, file hashes, code context, incremental updates", limit: 8)
  ⎿  {
       "success": false,
       "results": [],
       "total_returned": 0,
       "offset": 0,
       "message": "sqlite-vec extension must be loaded for vec0 virtual tables. Use connect(..., load_vec=True)"
     }
