WHAT IT DOES

What create_group_migration does on Mealie MCP Server

AI agents use create_group_migration 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.

WHY IT NEEDS A POLICY

Why create_group_migration needs a policy

The tool creates a group migration, which is a Write operation as it initializes/creates a new migration resource. Migrations typically import or transform data but are reversible in the sense that they create new records. Severity is medium because misuse could import unwanted data or affect group configuration, but it doesn't explicitly delete or overwrite existing data.
