pause · Filopastry MCP: Risk & Policy

WHAT IT DOES

What pause does on Filopastry

AI agents invoke pause to trigger actions in Filopastry. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why pause needs a policy

This tool triggers an external operation (pausing audio playback in the Strudel.cc environment). It has real-world side effects on the running audio system but is reversible (playback can be resumed), so it does not qualify as Destructive. Execute is the most appropriate category for triggering external system state changes. Blast radius is low as it only affects local audio playback.

Verdict

pause Rate-limited

pause stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about pause

What does the pause tool do? +

Pause playback. It is categorised as a Execute tool in the Filopastry MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pause? +

Register the Filopastry MCP server in PolicyLayer and add a rule for pause: 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 Filopastry. Nothing to install.

What risk level is pause? +

pause is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit pause? +

Yes. Add a rate_limit block to the pause 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.

How do I block pause completely? +

Set action: deny in the PolicyLayer policy for pause. 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.

What MCP server provides pause? +

pause is provided by the Filopastry MCP server (youwenshao/filopastry). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
