TL;DR

Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server error.

Guidance

• The error messages indicate that the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is missing, which is required for the MCP server to function correctly.
• To fix this, you need to set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable with a valid GitHub personal access token.
• You can do this by running the command export GITHUB_PERSONAL_ACCESS_TOKEN=your_token_here in your terminal, replacing your_token_here with your actual GitHub personal access token.
• Additionally, the rust-analyzer-lsp server is crashing repeatedly, which may be related to the MCP server error or a separate issue.

Example

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

Notes

The provided error messages are truncated, so there may be additional information or errors that are not visible. The solution provided assumes that the GITHUB_PERSONAL_ACCESS_TOKEN environment variable is the primary cause of the issue.

Recommendation

Apply workaround: Set the GITHUB_PERSONAL_ACCESS_TOKEN environment variable to resolve the MCP server error. This should allow the MCP server to function correctly and may also resolve the rust-analyzer-lsp server crashes.
