WHAT IT DOES

What add_favorite does on Mealie MCP Server

AI agents use add_favorite 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 add_favorite is rated Medium

This tool creates a new association between a user and a recipe in the favorites collection. It is a write operation that adds data (user preference state) but is reversible—the user can unfavorite a recipe later. It does not query data only (Read), execute arbitrary code (Execute), delete data (Destructive), or move money (Financial).

From the tool's definition Tool description states 'Add a recipe to the current user's favorites' — this creates a new favorite record, modifying user preferences reversibly.
