AI agents use playlists_create to create or update resources in Propresenter — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Propresenter environment.
This tool creates a new playlist, which is a reversible write operation. It adds data to the system but does not execute code, delete data, or move money. The blast radius is medium because improper creation of playlists could disrupt presentation workflows, but the operation is not permanent or destructive and can be undone through manual deletion or reversal.
From the tool's definition Tool name 'playlists_create' and description 'Create a new playlist' indicate creation of new data within ProPresenter 7.
Documented attack patterns abuse exactly the kind of access playlists_create 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 playlists_create:
{
"version": "1",
"default": "deny",
"tools": {
"playlists_create": {
"limits": [
{
"counter": "playlists_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}playlists_create 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.
Free to start. No card required.
Create a new playlist. It is categorised as a Write tool in the Propresenter MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Propresenter MCP server in PolicyLayer and add a rule for playlists_create: 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.
playlists_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the playlists_create 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 playlists_create. 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.
playlists_create 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.
