WHY IT NEEDS A POLICY

Why colab_drive_upload needs a policy

This tool uploads files to Google Drive, which is a data modification operation that creates or stores data reversibly. While the description is empty (lowering confidence slightly), the name and server context leave little doubt about its write functionality. Severity is high because an AI agent could upload sensitive data, overwrite important files, or fill storage quota if misused.

From the tool's definition Tool name 'colab_drive_upload' indicates uploading/writing data to Google Drive. Server description confirms 'Google Drive integration'. No description provided for the tool itself, but the name and server context make the write operation clear.
