Why uncollect_character needs a policy

This tool irreversibly removes a character from a user's collection. While it may be reversible by re-adding the character, deletion/removal operations are classified as Destructive. The blast radius is medium as it only affects the current user's collection data.

POLICY

How to control uncollect_character

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_character:

policy.json

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

uncollect_character 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.
