Misleading debug message when using environment variable expansion in Claude Code

[PaulRBerg]

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.

Hi @PaulRBerg, part of your issue body seems to be missing. Please could you let us know how you are connecting the GitHub MCP server with Claude Code, and whether you are using the remote HTTP or local version of the server.

Here are also some Claude Code docs that might be helpful:

• Environment variable expansion in .mcp.json
• Authenticate with remote MCP servers - to use OAuth for the Remote GitHub MCP server

sorry @LuluBeatson, I updated the OP

I am indeed using Claude Code, and I was using the remote HTTP

This seems like a Claude Code bug, @PaulRBerg have you found any solution?
