WHAT IT DOES

What unifi_block_client does on Multi-Tool MCP Server

AI agents invoke unifi_block_client to trigger actions in Multi-Tool 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.
