THE RISK

Critical Risk

Why delete_collection needs a policy

Deleting a collection is a destructive operation that irreversibly removes the collection schema and all contained data. This cannot be undone without a database backup. The critical severity reflects that an AI agent with misused access could erase entire data structures serving business operations. Admin-only access provides some mitigation but does not change the destructive nature of the operation itself.

From the tool's definition Tool name 'delete_collection' combined with description stating it deletes 'a collection from PocketBase' indicates irreversible removal of data structures and all associated records.

POLICY

How to control delete_collection

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

policy.json

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

delete_collection 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 PocketBase 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.
