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 correct format and scope of the personal access token.
• Consider setting the environment variable in your terminal configuration or shell startup script to ensure it is always available.

Notes

The provided errors are consistent and clearly indicate a missing environment variable. Setting the GITHUB_PERSONAL_ACCESS_TOKEN variable should resolve the MCP server error. However, the "Lock acquisition failed" error may be related to a different issue and may require further investigation.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server error, as it is the most direct solution to the reported issue.
