I am using the GitHub MCP server like this:

    "github": {
      "type": "http",
      "url": "https://api.githubcopilot.com/mcp",
      "headers": {
        "Authorization": "Bearer ${GITHUB_TOKEN}"
      }
    }

The environment variable is loaded correctly by Claude Code and I am able to interact with my GitHub account.

However, I noticed that when I run claude --debug, I am seeing these logs:

[DEBUG] MCP server "github": No token data found

These debug messages are misleading the token is loaded, but it's loaded via an environment variable.
