WHAT IT DOES

What tesla_set_temp does on Mcp Teslamate Fleet

AI agents invoke tesla_set_temp to trigger actions in Mcp Teslamate Fleet. 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 tesla_set_temp needs a policy

This tool sends a command to a physical vehicle to change its climate control settings. It triggers an external operation (modifying vehicle HVAC state) rather than simply reading or writing data in a database. While it is reversible (temperature can be changed again), it constitutes executing a remote command on a physical device.

From the tool's definition Set cabin temperature target (Fahrenheit). Both driver and passenger.
