Implementation Reference

• mcp_router.py:82-112 (handler)

  The main handler function for the 'add_mcp_server' tool. It serializes the provided tools to JSON and calls the discovery_service.add_server method to register the new MCP server, returning the result as JSON.

  @mcp.tool()
  async def add_mcp_server(
      server_name: str, 
      server_description: str, 
      server_endpoint: str, 
      tools: List[Dict[str, Any]]
  ) -> str:
