Honcho MCP Server

A remote MCP server for Honcho, providing AI memory and personalization tools to LLM clients like Claude Desktop.

Clients connect over HTTP SSE — no local process spawning, no stdio bridge needed.

Connect

Add the server URL to your MCP client config:

Note: User identity (peer_id) is set through Honcho tool calls —the X-Honcho-* headers in the MCP config below are optional metadataand not consumed by the Honcho SDK.The server handles both SSE (GET) and JSON-RPC (POST) at the root / path.

  "servers": {
    "honcho": {

      }
    }
  }
