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 the MCP server to function correctly.
• To verify, check if the GITHUB_PERSONAL_ACCESS_TOKEN variable is set in your environment by running echo $GITHUB_PERSONAL_ACCESS_TOKEN in your terminal.
• If the variable is not set, create a new personal access token in your GitHub account settings and set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to the new token value.
• Restart your application or terminal session to apply the changes.

Example

No code snippet is provided as it's not necessary for this specific issue.

Notes

The issue seems to be related to a missing environment variable, which is a common configuration issue. Setting the GITHUB_PERSONAL_ACCESS_TOKEN variable should resolve the error.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server error. This is the most straightforward solution to the problem, and it does not require any version upgrades or code changes.
