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.
• Verify that the GITHUB_PERSONAL_ACCESS_TOKEN variable is set in your environment before running the application.
• If the issue persists, check the file system permissions and ensure that the application has the necessary permissions to read and write files.

Notes

• The provided error messages are truncated, which may limit the ability to provide a comprehensive solution.
• The EISDIR: illegal operation on a directory, read error suggests a potential issue with file system operations, but without more information, it is difficult to provide a specific solution.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the mcp-config-invalid error, as this is the most straightforward solution based on the provided error messages.
