disconnect_client · UniFi MCP Server MCP: Risk & Policy

WHAT IT DOES

What disconnect_client does on UniFi MCP Server

AI agents invoke disconnect_client to trigger actions in UniFi MCP Server. 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 disconnect_client needs a policy

This tool forces a network disconnection event on a client device, which is an active operation with immediate real-world effects. It is not merely destructive (no data is permanently deleted) but it executes a network management action that can disrupt user connectivity. It falls under Execute as it triggers an external operation on network infrastructure.

From the tool's definition 'Force disconnect a client from the network' — actively triggers an external network operation that disrupts a connected client's session

disconnect_client Rate-limited

disconnect_client 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.
