Connecting to Cursor

Add the following to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "shellserver": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/sami/Documents/MCP/mcp-servers/shellserver",
        "run",
        "server.py"
      ]
    }

}

Then restart Cursor. The terminal tool will be available to the Agent.

Security
