Cursor agent unable to use the HuggingFace MCP tools

[deanrie]

Thanks for the logs - I see “Found 9 tools, 4 prompts” via mcp-remote and multiple CreateClient (“A second client was created while connecting, discarding it.”). It looks like duplicate configuration for the same server.

Please check:

1. Duplicates in the config
   • Open both files and send their contents:
     • Global: ~/.cursor/mcp.json
     • Project: .cursor/mcp.json
   • Make sure “hf-mcp-server” is described in only one place. Either remove the duplicate or rename the entry for mcp-remote, for example to “hf-mcp-remote”.
2. Enabling tools
   • In the chat, open “Available Tools” and check that the HF group is enabled (toggle is active).
3. Logs + Request ID
   • Create a new chat, ask the Agent to explicitly use the HF-tool, then:
     • Copy the Request ID (chat menu → Copy Request ID)
     • Open Output Cmd+Shift+U → select “MCP Logs” and send the logs around this attempt.
4. Try in Agent Window and in the main editor - write where it reproduces.
5. Network test
   • Settings → Network → Run Diagnostics
   • Temporary test: Settings → “Disable HTTP/2” → restart Cursor → repeat the attempt.

If the problem persists after removing duplicates and restarting, send:

• New Request ID after mcp-remote
• MCP Logs from Output
• Contents of both mcp.json
  I’ll attach this data to the investigation with the engineers.
