This tool retrieves a list of artists from a music library (Navidrome). It performs no mutations, deletions, or side effects. It is a straightforward read operation querying existing data. The blast radius of misuse is minimal - an AI could only enumerate artists in the library, posing no security or operational risk.

From the tool's definition Tool name contains 'list' operation and description states "List all artists in the Navidrome library" - this is a query operation that retrieves data without modification.

POLICY

How to control crow_navidrome_artists

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_navidrome_artists:

policy.json

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

crow_navidrome_artists 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.
