extent analysis

TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server 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 fix this, you need to set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable in your system or in the VSCode terminal before running the Claude code.
  • You can set environment variables in VSCode by running the command set GITHUB_PERSONAL_ACCESS_TOKEN=your_token in the terminal, replacing your_token with your actual GitHub personal access token.
  • Ensure that you have generated a GitHub personal access token with the necessary permissions and have replaced your_token with the actual token value.

Notes

The provided solution assumes that you have already generated a GitHub personal access token. If not, you will need to create one in your GitHub account settings before setting the environment variable.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable, as this is the most direct solution to the error messages provided.
