RECOMMENDED RULE

The rule that runs playlist_intersection safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Spotify, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For playlist_intersection, this is the rule to start with:

playlist_intersection Allowed

playlist_intersection is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Spotify, apply this rule, and every playlist_intersection call is checked against it from then on.
