WHAT IT DOES

What export_library_json does on Spotify

AI agents use export_library_json to create or update resources in Spotify, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Spotify environment.

RISK

Why export_library_json is rated Medium

An AI agent can call export_library_json faster than any human can review: one bad instruction and it creates or modifies resources in Spotify by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs export_library_json 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 export_library_json, this is the rule to start with:

export_library_json Rate-limited

export_library_json stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "export_library_json": {
      "limits": [
        {
          "counter": "export_library_json_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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