Use this when the user asks to end the listening session, stop listening to music, close the player, or stop the music program. It stops mpv playback, clears listening state, and closes the current web player server, while keeping the MCP tool process alive for future calls.
AI agents call shutdown to permanently remove resources in Netease Music — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly terminates active playback, clears session state, and closes the web player server. While it doesn't delete user data, it non-reversibly tears down running services and session state. The MCP process itself survives, but the listening session and server are destroyed.
From the tool's definition stops mpv playback, clears listening state, and closes the current web player server
Documented attack patterns abuse exactly the kind of access shutdown gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Netease Music, and nothing reaches the server without passing your rules. This is the rule we recommend for shutdown:
{
"version": "1",
"default": "deny",
"hide": [
"shutdown"
]
}shutdown disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Use this when the user asks to end the listening session, stop listening to music, close the player, or stop the music program. It stops mpv playback, clears listening state, and closes the current web player server, while keeping the MCP tool process alive for future calls. It is categorised as a Destructive tool in the Netease Music MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Netease Music MCP server in PolicyLayer and add a rule for shutdown: 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 Netease Music. Nothing to install.
shutdown is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the shutdown 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 shutdown. 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.
shutdown is provided by the Netease Music MCP server (luuu-h/netease-music-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Netease Music, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
