THE RISK

Low Risk

Why get_character_subjects needs a policy

This tool retrieves and queries information about which anime, games, or other media contain a specific character. It performs a read-only lookup against the BangumiTV database with no capacity to modify, delete, or execute operations. The blast radius of misuse is minimal—worst case, an agent could spam requests or scrape data, but no data integrity or system state is at risk.

From the tool's definition Tool description states it 'List subjects' (characters appear in) - a retrieval operation with no modification or side effects. The verb 'list' and the passive context of querying where a character appears indicates data retrieval only.

POLICY

How to control get_character_subjects

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_character_subjects:

policy.json

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

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

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.
