Describe the Bug
Hello, I am trying to add a custom MCP server for the Hibob integration on macOS, but the agent does not appear in the agent list. We have performed extensive troubleshooting and confirmed the issue is likely a bug in Cursor.
Steps to Reproduce
- System State:
The uvx command-line tool is successfully installed at /Users/mprodan/.local/bin/uvx.
Running the command manually in the terminal works perfectly. The command uvx hibob-public-mcp (with the HIBOB_API_TOKEN environment variable set) successfully starts the “FastMCP” server.
- Cursor Configuration:
The correct settings.json file at ~/Library/Application Support/Cursor/User/settings.json is configured as follows:
JSON
{
“window.commandCenter”: true,
“mcpServers”: {
“HiBob MCP Server”: {
“command”: “/Users/xxxxx/.local/bin/uvx”,
“args”: [“hibob-public-mcp”],
“env”: {
“HIBOB_API_TOKEN”: “YOUR_API_TOKEN”
}
}
}
}
3. Result:
Despite the correct configuration and the command working manually, the “HiBob MCP Server” agent never appears in the agent dropdown list after restarting Cursor.
There are no relevant errors in the Output > Log (Window) or Output > Agent Host panels.
It seems there is an issue with how this version of Cursor is spawning or detecting the external MCP process on macOS. Please let me know if you need any more information.
