THE RISK

Critical Risk

Why uncollect_person needs a policy

This tool irreversibly removes an item from a user's collection. While it may be possible to re-add the person, the act of removal is a destructive operation that deletes an existing relationship/record. It falls under Destructive as it deletes data, though severity is medium since it only affects a user's personal collection entry rather than shared or critical data.

From the tool's definition Remove a person from the current user's collection

POLICY

How to control uncollect_person

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

policy.json

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

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