TL;DR

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

Guidance

• The errors 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 application.
• Check the documentation for the application to ensure that the token is being used correctly and that there are no other required environment variables.
• If the issue persists, try checking the application logs for more detailed error messages.

Example

No code example is provided as the issue is related to environment variable configuration.

Notes

The provided errors suggest that the issue is related to the MCP server configuration and the missing GITHUB_PERSONAL_ACCESS_TOKEN environment variable. However, there are other errors reported, such as "Request was aborted" and "Internal server error", which may indicate additional issues.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server error. This should allow the application to function correctly, but may not address the underlying cause of the other reported errors.
