Delete a specific category. Args: category_id: The UUID of the category to delete Returns: Dict[str, Any]: Confirmation of deletion
AI agents call delete_category to permanently remove resources in Mealie MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a category from the Mealie recipe database. Deletion cannot be undone and will affect any recipes or meal plans associated with that category. While the blast radius is somewhat contained (deleting a category rather than bulk data), the irreversible nature and potential downstream impact on data organization justify 'high' severity in a high/medium context.
From the tool's definition Tool name is 'delete_category' and description explicitly states 'Delete a specific category.' The return type 'Confirmation of deletion' confirms the action is irreversible.
Documented attack patterns abuse exactly the kind of access delete_category gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mealie MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_category:
{
"version": "1",
"default": "deny",
"hide": [
"delete_category"
]
}delete_category disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a specific category. Args: category_id: The UUID of the category to delete Returns: Dict[str, Any]: Confirmation of deletion. It is categorised as a Destructive tool in the Mealie MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mealie MCP Server 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 Mealie MCP Server. 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 Mealie MCP Server MCP server (rldiao/mealie-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
