Changelog Entry

Description

External tools of type "MCP" that are disabled in the backend, still show up and can be used in the frontend.

Fixed

  • Disabled external tools of type MCP are now filtered from the integrations menu and the model tool list in the frontend.

Additional Information

The issue seems to be that the code is discriminating external tools by type. OpenAPI type tools are listed using the method get_tool_servers_data that provides validation to ensure the tool is enabled. But external tools of type "MCP" (streamables) have a custom function that does not validates if the tools is disabled in the backend.

This fix ensures that disabled MCP tools are filtered out in the frontend.

Code snippet:

    # MCP Tool Servers
    for server in request.app.state.config.TOOL_SERVER_CONNECTIONS:
        if server.get("type", "openapi") == "mcp" and server.get("config", {}).get("enable", True): # <-- FIX
            server_id = server.get("info", {}).get("id")
            auth_type = server.get("auth_type", "none")

            session_token = None
            if auth_type == "oauth_2.1":
                splits = server_id.split(":")
                server_id = splits[-1] if len(splits) > 1 else server_id

                session_token = (
                    await request.app.state.oauth_client_manager.get_oauth_token(
                        user.id, f"mcp:{server_id}"
                    )
                )
