reconnect_client · UniFi MCP Server MCP: Risk & Policy

WHAT IT DOES

What reconnect_client does on UniFi MCP Server

AI agents invoke reconnect_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 reconnect_client needs a policy

This tool triggers an external operation (forcing a client to disconnect and reconnect) on the network. It doesn't just read data or write configuration—it actively disrupts an existing client connection. The effect is transient (client reconnects), so it's not destructive, but it does execute a real-time network action whose impact depends on which client is targeted.

reconnect_client Rate-limited

reconnect_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.
