delete_tag

THE RISK

Critical Risk

This tool permanently removes data (a tag) from the Mealie recipe database. Deletion is irreversible and cannot be undone, making it Destructive rather than Write. Severity is medium because tags are metadata references; their deletion may orphan associations but unlikely to trigger critical system failure. Confidence is high because the intent is unambiguous from both name and description.

From the tool's definition Tool name is 'delete_tag' and description explicitly states 'Delete a specific tag' with confirmation of deletion returned. The action is irreversible.

Documented attack patterns abuse exactly the kind of access delete_tag gives an agent:

HOW TO CONTROL DELETE_TAG

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_tag:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_tag"
  ]
}

delete_tag disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Mealie MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
