Why delete_actor_item needs a policy

This tool permanently removes items from actor inventories in a tabletop gaming session. While the impact is scoped to a single actor's item (not the entire character or campaign), deletion is irreversible and represents data loss. The high confidence reflects the unambiguous destructive intent in both the name and description.

From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete an item owned by an actor'. The tool irreversibly removes data from the game state.

POLICY

How to control delete_actor_item

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

policy.json

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

delete_actor_item 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 FoundryVTT 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.
