Why get_user_character_collection needs a policy

This tool performs a read-only operation to fetch user collection metadata. It has no side effects, does not modify data, execute code, delete information, or involve financial transactions. The blast radius of misuse is minimal—an attacker could only learn which characters a user has collected, which is low-sensitivity user preference data.

From the tool's definition The tool 'get_user_character_collection' retrieves collection status information for a character. The verb 'get' combined with 'collection status' indicates a query operation that returns data without modifying or executing external actions.

How to control get_user_character_collection

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 get_user_character_collection:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_user_character_collection": {}
  }
}

get_user_character_collection is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
