WHAT IT DOES

What patch_recipe does on Mealie MCP Server

AI agents use patch_recipe 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 patch_recipe is rated Medium

The tool performs a partial update (PATCH operation) on recipe data, which is a write operation that modifies existing data but can be undone by patching again or reverting changes. This is reversible (unlike delete/destructive operations) and does not execute arbitrary code, trigger external systems, or move financial resources.

From the tool's definition Tool name 'patch_recipe' and description 'Partially update an existing recipe in Mealie' indicate a reversible modification operation on recipe data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs patch_recipe safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mealie MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For patch_recipe, this is the rule to start with:

patch_recipe Rate-limited

patch_recipe stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
