Implementation Reference
- src/mem0_mcp_server/server.py:390-400 (handler)The main handler function for the 'update_memory' tool. It is decorated with @server.tool, which registers it with the FastMCP server. The function calls the Mem0 client's update method to overwrite the memory text given a memory_id.
@server.tool(description="Overwrite an existing memory’s text.") def update_memory( memory_id: Annotated[str, Field(description="Exact memory_id to overwrite.")], text: Annotated[str, Field(description="Replacement text for the memory.")], ctx: Context | None = None, ) -> str: """Overwrite an existing memory’s text after the user confirms the exact memory_id.""" api_key, _, _ = _resolve_settings(ctx) client = _mem0_client(api_key) return _mem0_call(client.update, memory_id=memory_id, text=text)
