WHAT IT DOES

What create_category does on Mealie MCP Server

AI agents use create_category 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 create_category is rated Medium

The tool creates new metadata (a recipe category) within the Mealie instance without modifying existing data or triggering external operations. This is a standard Write operation with minimal blast radius—a misconfigured or malicious category creation would only clutter the system but would not corrupt, delete, or compromise data.

From the tool's definition Tool name 'create_category' and description 'Create a new recipe category' indicate a data creation operation. This is reversible (categories can typically be deleted or modified) and has no destructive or external execution effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_category 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 create_category, this is the rule to start with:

create_category Rate-limited

create_category 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.
