Delete a category by UUID.
AI agents call delete_category to permanently remove resources in Mcp Mealie — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs an irreversible deletion operation on taxonomy data (categories). Once deleted, the category cannot be recovered through normal means. While the blast radius is limited to a single category rather than an entire database, the destructive nature of the operation and potential cascade effects on recipes or meal plans that reference the deleted category justify the 'high' severity classification.
From the tool's definition Tool name is 'delete_category' and description states 'Delete a category by UUID.' The verb 'delete' combined with the action of removing a category entry indicates irreversible data removal.
Attacks that exploit this kind of access
Delete a category by UUID. It is categorised as a Destructive tool in the Mcp Mealie MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Mealie MCP server in PolicyLayer and add a rule for delete_category: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Mealie. Nothing to install.
delete_category is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_category rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_category. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_category is provided by the Mcp Mealie MCP server (obrien-matthew/mcp-mealie). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
