TL;DR

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

Guidance

• The error messages indicate a missing GREPTILE_API_KEY environment variable, which is required for the MCP server to function correctly.
• To mitigate the issue, set the GREPTILE_API_KEY environment variable before running the application.
• Verify that the environment variable is set correctly by checking the application logs or using a debugging tool.
• If the issue persists, check the application configuration to ensure that the GREPTILE_API_KEY variable is being used correctly.

Notes

The provided error messages suggest that the issue is related to a missing environment variable, but the root cause of the problem may be more complex. Additional debugging or configuration changes may be required to fully resolve the issue.

Recommendation

Apply workaround: Set the GREPTILE_API_KEY environment variable to resolve the MCP server error, as this is the most direct solution implied by the error messages.
