WHAT IT DOES

What connect_robot does on Universal Robot MCP Server

AI agents invoke connect_robot to trigger actions in Universal Robot 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 connect_robot needs a policy

Connecting to a physical robot establishes a real-time control session, which is an external operation with significant physical-world implications. While the description is empty (lowering confidence), the server context makes clear this initiates a live robot control connection — a prerequisite for motion commands. This falls under Execute as it triggers an external operation.

From the tool's definition Tool name 'connect_robot' on a server that 'Enables AI assistants to control Universal Robots through real-time connection management'; description is empty.
