AI agents call audio_get_playlists to retrieve information from Propresenter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves information about existing audio playlists. It has no side effects, does not modify data, and does not execute external commands. The blast radius of misuse is minimal — an attacker would only gain visibility into configured playlists.
From the tool's definition Tool name is 'audio_get_playlists' and description states 'Get a list of all configured audio playlists' — retrieves/queries data without modification.
Documented attack patterns abuse exactly the kind of access audio_get_playlists gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Propresenter, and nothing reaches the server without passing your rules. This is the rule we recommend for audio_get_playlists:
{
"version": "1",
"default": "deny",
"tools": {
"audio_get_playlists": {}
}
} audio_get_playlists is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a list of all configured audio playlists. It is categorised as a Read tool in the Propresenter MCP Server, which means it retrieves data without modifying state.
Register the Propresenter MCP server in PolicyLayer and add a rule for audio_get_playlists: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Propresenter. Nothing to install.
audio_get_playlists is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the audio_get_playlists rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for audio_get_playlists. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
audio_get_playlists is provided by the Propresenter MCP server (@alxpark/propresenter-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Propresenter, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
