Delete a measurement unit from Mealie.
AI agents call delete_unit 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 deletes data that cannot be recovered. While deleting a unit has moderate scope (affects measurements rather than recipes or user data directly), the irreversible nature and potential cascade effects (any recipes using that unit could be affected) classify it as Destructive.
From the tool's definition Tool performs deletion of a measurement unit: 'Delete a measurement unit from Mealie.' The operation is irreversible and removes data permanently.
Attacks that exploit this kind of access
Delete a measurement unit from Mealie. 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_unit: 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_unit 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_unit 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_unit. 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_unit is provided by the Mealie MCP Server MCP server (nikopol666/mealie-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
