On Mac OS there is a common issue with uv paths and Claude Desktop, usually it is a must to specify the full path to uv rather than just using command uv to run the server. I got this issue and had to download extension source code and change the line in manifest.json
"command": "uv" to "command": "/Users/artbred/.local/bin/uv"
Hope this will be helpful for someone
