Create a setlist of songs
AI agents use crow_create_setlist to create or update resources in Crow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crow environment.
Creating a setlist is a reversible write operation that adds new data to the project management system. It does not execute code, delete data, or trigger financial transactions. The blast radius of misuse is minimal—an agent could create unwanted setlists, but these can be deleted or modified. Severity is low because the impact is confined to music/playlist data within the project management context.
From the tool's definition Tool name 'crow_create_setlist' and description 'Create a setlist of songs' indicate a create operation that adds new data (a setlist) to the system.

PolicyLayer is an MCP gateway — it sits between your AI agents and Crow, and nothing reaches the server without passing your rules. This is the rule we recommend for crow_create_setlist:
{
"version": "1",
"default": "deny",
"tools": {
"crow_create_setlist": {
"limits": [
{
"counter": "crow_create_setlist_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}crow_create_setlist 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.

Create a setlist of songs. It is categorised as a Write tool in the Crow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Crow MCP server in PolicyLayer and add a rule for crow_create_setlist: 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 Crow. Nothing to install.
crow_create_setlist 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 crow_create_setlist 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 crow_create_setlist. 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.
crow_create_setlist is provided by the Crow MCP server (kh0pper/crow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Crow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
