THE RISK

Low Risk

Why crow_list_setlists needs a policy

This tool retrieves data (setlists) and has no side effects. It matches the 'Read' category definition: retrieves or queries data with no side effects. The blast radius of misuse is minimal—an agent could only enumerate setlists, not modify, delete, or execute code. Severity is low because listing data carries negligible operational risk.

From the tool's definition Tool name and description indicate a list operation: 'crow_list_setlists' performs 'List setlists', which retrieves or queries existing setlist data without modification, deletion, or execution of external operations.

POLICY

How to control crow_list_setlists

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

policy.json

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

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