TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the mcp-config-invalid error.

Guidance

1. Identify the missing environment variable: The error messages indicate that GITHUB_PERSONAL_ACCESS_TOKEN is missing.
2. Set the environment variable: Configure your system or application to set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable with a valid GitHub personal access token.
3. Verify token validity: Ensure the token has the necessary permissions and is not expired.
4. Test the application: After setting the environment variable, retry the operation that previously failed to verify the fix.

Example

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

Notes

The provided error messages suggest that the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is required for the application to function correctly. Setting this variable should resolve the mcp-config-invalid error. However, the issue content was truncated, so additional errors or context might be missing.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable. This should resolve the immediate error, but further investigation may be needed to address any underlying issues or additional errors not visible due to truncation.
