Stops music playback entirely and closes the player.
AI agents invoke stop_music to trigger actions in Yit Player. 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.
stop_music triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
Stops music playback entirely and closes the player. It is categorised as a Execute tool in the Yit Player MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Yit Player MCP server in PolicyLayer and add a rule for stop_music: 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 Yit Player. Nothing to install.
stop_music is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the stop_music 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 stop_music. 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.
stop_music is provided by the Yit Player MCP server (vijayarajparamasivam/yit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
