TL;DR

Set the GREPTILE_API_KEY environment variable to resolve the mcp-config-invalid error.

Guidance

• The error messages indicate a missing GREPTILE_API_KEY environment variable, which is required for the MCP server greptile to function correctly.
• To mitigate the issue, set the GREPTILE_API_KEY environment variable before running the task.
• Verify that the environment variable is set correctly by checking the variable's value in your terminal or environment settings.
• If the issue persists, check the documentation for the MCP server greptile to ensure that the GREPTILE_API_KEY is set up correctly.

Example

export GREPTILE_API_KEY=your_api_key_here

Replace your_api_key_here with your actual API key.

Notes

The provided error messages suggest that the GREPTILE_API_KEY environment variable is not set, which is causing the MCP server greptile to fail. Setting this variable should resolve the issue. However, without more information about the MCP server greptile configuration, it's difficult to provide a more detailed solution.

Recommendation

Apply the workaround by setting the GREPTILE_API_KEY environment variable, as this is the most likely cause of the issue.
