TL;DR

The issue seems to be related to missing tools, specifically Tool TodoWrite and mcp__plugin_easypanel_easypanel__ep_deploy_app, which are not found, leading to a 400 error.

Guidance

• Check the configuration and installation of the tools mentioned in the error messages to ensure they are properly set up and accessible.
• Verify that the versions of the tools and the application are compatible, as the issue might be related to version mismatches.
• Review the application's documentation to see if there are specific requirements or settings needed for the tools to function correctly.
• Consider reinstalling or updating the tools to the latest version to resolve potential compatibility issues.

Example

No specific code example can be provided without more context, but checking the tool configurations and versions can be done through the application's settings or configuration files.

Notes

The issue description is truncated, which might limit the ability to provide a comprehensive solution. The errors suggest a problem with tool availability, but without the full context, it's challenging to offer a definitive fix.

Recommendation

Apply a workaround by checking and potentially reinstalling or updating the missing tools, as this seems to be the most direct approach to resolving the issue based on the provided error messages.
