TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server error.

Guidance

• The error messages indicate a missing GITHUB_PERSONAL_ACCESS_TOKEN environment variable, which is required for GitHub authentication.
• Verify that the GITHUB_PERSONAL_ACCESS_TOKEN variable is set in your environment before running the application.
• Check the documentation for the specific command or application being used to see if there are any specific instructions for setting environment variables.
• Consider setting the GITHUB_PERSONAL_ACCESS_TOKEN variable in a secure location, such as an environment file or a secrets manager, to avoid exposing sensitive information.

Notes

The issue seems to be related to a missing environment variable, which is a common configuration issue. However, without more information about the specific application or command being used, it's difficult to provide more detailed guidance.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the issue, as it is a required configuration for GitHub authentication.
