THE RISK

Critical Risk

Why delete-key needs a policy

Deleting an API key is a destructive action—once removed, the key is permanently lost and cannot be recovered through normal means. This is more severe than a Write operation (which is reversible) because deletion is irreversible. While not as critical as financial impact, a deleted API key could break integrations and access controls, making this a high-severity destructive action.

From the tool's definition Tool name is 'delete-key' with description 'Delete an existing API key'. The verb 'delete' and the action of removing an API key are irreversible operations that cannot be undone.

Documented attack patterns abuse exactly the kind of access delete-key gives an agent:

POLICY

How to control delete-key

PolicyLayer is an MCP gateway — it sits between your AI agents and Meilisearch MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-key:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete-key"
  ]
}

delete-key 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 Meilisearch 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.
