This is the first time I’ve used an MCP server so I might be overlooking something obvious; I seem to have the MCP server configured correctly in Cursor AI but it doesn’t seem to be working. Running mcp_server.py from the command line works, just not from Cursor.

Any ideas on how to fix it?

Did you get it figured out, @dant3ch? I am running into he same problem. I had it try to look at the port 8100 but that didn’t seem to work either.

@kineticasey / @colum / @dant3ch / @Meh-S-Eze I believe I’ve figured out the problem for Docker and Cursor! The command I was giving in the UI was incorrect. I pushed a commit to fix it, and also here is the right command:

docker run -i --rm -e GRAPH_SERVICE_URL=http://host.docker.internal:8100 archon-mcp:latest

Please let me know if this works for you! Didn’t get a chance to test it myself since I don’t have Cursor on the PC I’m using right now but I will later.

@dant3ch I see you’re using Python and not Docker - your command looks good except the path to Python seems incorrect. Not sure why it’s just python.exe and not the full path to the Python executable in the virtual environment. Have you tried with Docker?
