MCP using gitmcp

[ErnstHolger]

I'm trying to get gitmcp to work:
https://gitmcp.io/

using the following config in the yaml file:

mcpServers:
gitmcp:
# type: sse # type can optionally be omitted
url: https://gitmcp.io/langchain-ai/langgraph
timeout: 60000

But it doesnt show up in the menu, also dont see the agent.

Any idea

Using the docker deployment.

Thanks for reaching out. I can’t test this server at the moment but will soon.

In the meantime, Please paste relevant logs that were created when reproducing the error.

Log locations:

• Docker: Project root directory ./logs
• npm: ./api/logs

There are two types of logs that can help diagnose the issue:

• debug logs (debug-YYYY-MM-DD.log)
• error logs (error-YYYY-MM-DD.log)

Error logs contain exact stack traces and are especially helpful, but both can provide valuable information.

Please only include the relevant portions of logs that correspond to when you reproduced the error.
