TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the mcp-config-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.
• To mitigate the issue, set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable in your terminal or vscode settings before running the API calls.
• Verify that the environment variable is set correctly by checking the output of the echo $GITHUB_PERSONAL_ACCESS_TOKEN command in your terminal.
• If you are using vscode, you can set the environment variable in the launch.json file or in the vscode settings.

Notes

The provided error messages suggest that the issue is related to a missing environment variable, but the root cause of the ERR_STREAM_PREMATURE_CLOSE error is unclear and may require further investigation.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the mcp-config-invalid error, as this is the most direct solution to the problem described in the error messages.
