The problem was reproduced independently by me and my colleague on different Macs.

We were trying to install MCP for Windsurf, latest version and failed.

I tried to build it and use this config:

"github": {"command":"/opt/tmp/github-mcp-server/cmd/github-mcp-server/github-mcp-server","args": ["stdio","--log-file=/tmp/github-mcp.log","--enable-command-logging"      ],"env": {"GITHUB_PERSONAL_ACCESS_TOKEN":"<redacted>"      }    }

Here's the error:

Here's the log:
github-mcp.log

As I can see, the error occurs on the initial stage of parsing tools.

Versions: latest revision of Github MCP, latest Windsurf.
Latest MacOS.
