extent analysis

TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the "MCP server github invalid" error.

Guidance

  • The error messages indicate a missing GITHUB_PERSONAL_ACCESS_TOKEN environment variable, which is required for the MCP server to function correctly.
  • Verify that the GITHUB_PERSONAL_ACCESS_TOKEN variable is set in your environment before running the claude command.
  • To set the environment variable, you can use the command export GITHUB_PERSONAL_ACCESS_TOKEN=your_token_value (replace your_token_value with your actual GitHub personal access token).
  • If you are using a GitHub personal access token, ensure it has the necessary permissions and is not expired.

Example

export GITHUB_PERSONAL_ACCESS_TOKEN=ghp_your_token_value
claude --teleport session_01XjeWZ4N8ZcmnKHgC18s8dG

Notes

The provided solution assumes that the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is the only missing requirement. If additional environment variables or configuration settings are required, they may need to be set as well.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable, as it is the most direct solution to the error message.
