THE RISK

Critical Risk

Why microcms_delete_media needs a policy

This tool performs irreversible deletion of media assets in a CMS. Even though there are constraints (media referenced by content cannot be deleted), the core function is to permanently remove media files, which is a destructive action. The blast radius is high because accidentally deleting media could break content dependencies and require recovery from backups.

From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete media files from microCMS'. The description confirms irreversible deletion: 'Media referenced by content cannot be deleted' indicates this is a destructive operation that cannot be undone.

POLICY

How to control microcms_delete_media

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

policy.json

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

microcms_delete_media 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 microCMS 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.
