THE RISK

Low Risk

Why get_lastfm_top needs a policy

This tool retrieves historical music preference data from Last.fm. It has no side effects, performs no modifications to any data, and cannot delete or execute arbitrary operations. The only risk is exposing personal listening history, which is low severity as it involves non-sensitive profile information typically public or semi-public on Last.fm. This is a straightforward Read operation.

From the tool's definition Tool name 'get_lastfm_top' and description 'Get top artists or tracks for ${this.config.username}' indicate data retrieval from Last.fm without modification or deletion. The function queries user's music listening history to return top artists/tracks.

POLICY

How to control get_lastfm_top

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

policy.json

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

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