WHAT IT DOES

What upload_admin_backup does on Mealie MCP Server

AI agents use upload_admin_backup to create or update resources in Mealie MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mealie MCP Server environment.

RISK

Why upload_admin_backup is rated Medium

This tool modifies the Mealie system by uploading and restoring backup archives. While backups can theoretically contain destructive operations when restored, the tool itself is performing an upload/write operation that persists data to the system.

From the tool's definition Tool name 'upload_admin_backup' and description 'Upload a Mealie backup archive from base64 data' indicates the tool creates/modifies system state by ingesting backup data into the system.
