props_delete_collection

THE RISK

Critical Risk

Why props_delete_collection needs a policy

The tool performs an irreversible deletion operation on prop collections in ProPresenter 7. Even though the blast radius is limited to presentation props rather than critical system data, deletion of collections cannot be undone and represents loss of user work. This meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.'

From the tool's definition Tool name contains 'delete' and description states 'Delete a specific prop collection' — this is an irreversible removal of data.

POLICY

How to control props_delete_collection

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

policy.json

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

props_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 Propresenter — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
