Additional Context

This appears to be a problem with Astral uvx running on MacOS. The following can be used as a workaround.

1. Clone this project.
2. Configure the mcp.json to use uv rather than uvx.

{
  "mcpServers": {
    "codelogic-mcp-server": {
      "type": "stdio",
      "command": "<PATH_TO_UV>/uv",
      "args": [
        "--directory",
        "<PATH_TO_THIS_REPO>/codelogic-mcp-server-main",
        "run",
        "codelogic-mcp-server"
      ],
      "env": {
        "CODELOGIC_SERVER_HOST": "<url to the server e.g. https://myco.app.codelogic.com>",
        "CODELOGIC_USERNAME": "<my username>",
        "CODELOGIC_PASSWORD": "<my password>",
        "CODELOGIC_MV_NAME": "<my workspace>",
        "CODELOGIC_DEBUG_MODE": "true"
      }
    }
  }
}

3. Restart Cursor.
4. Make sure the Cursor Global Rule is in place.
5. Refresh codelogic-mcp-server in the Cursor MCP tab.
6. Ask Cursor to make a code change in an existing class, the MCP server will now run the impact analysis.
