List videos. scope: local (this instance), federated (all), subscriptions (my follows). Rate-limited: 60/hour.
AI agents call pt_list_videos to retrieve information from Crow without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates video data from a video-sharing platform. It performs a read-only query operation across different scopes without creating, modifying, deleting, or executing anything. The rate limit (60/hour) is a safety measure typical of read operations. No destructive, financial, or execution risks are present.
From the tool's definition Tool name 'pt_list_videos' and description 'List videos' indicate data retrieval with no modification or side effects. The scope options (local, federated, subscriptions) are query parameters that determine what data to retrieve, not actions that alter state.
Documented attack patterns abuse exactly the kind of access pt_list_videos gives an agent:
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 pt_list_videos:
{
"version": "1",
"default": "deny",
"tools": {
"pt_list_videos": {}
}
}pt_list_videos is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List videos. scope: local (this instance), federated (all), subscriptions (my follows). Rate-limited: 60/hour. It is categorised as a Read tool in the Crow MCP Server, which means it retrieves data without modifying state.
Register the Crow MCP server in PolicyLayer and add a rule for pt_list_videos: 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.
pt_list_videos 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 pt_list_videos 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 pt_list_videos. 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.
pt_list_videos 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.
Free to start. No card required.
