It may caused by "uvx mcp-server-fetch" doesn't finish in 10 seconds and add_mcp_tools_to_agent timeout. I think add a installed one in runtime docker image may solve this.

Do you mean add a mcp serve in config file ?

Add this to runtime docker file RUN apt update & apt install pipx & pipx install mcp-server-fetch

I am experiencing the same issue. Is it possible to disable MCP tool while running.in headless mode via any environment variable
