wake_up · Tesla MCP Server MCP: Risk & Policy

WHAT IT DOES

What wake_up does on Tesla MCP Server

AI agents invoke wake_up to trigger actions in Tesla 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 wake_up needs a policy

This tool sends a command to an external physical device (Tesla vehicle) to change its state from sleep to active. It is not merely reading data, nor does it write/modify stored data — it triggers an external operation. While reversible (the car will go back to sleep), it executes an action with real-world effects on a physical asset.

From the tool's definition Wake up your Tesla vehicle from sleep mode — triggers an external operation on a physical vehicle

Verdict

wake_up Rate-limited

wake_up 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Tesla MCP Server, so you can run agents against it safely.

FAQ

Questions about wake_up

What does the wake_up tool do? +

Wake up your Tesla vehicle from sleep mode. Requires vehicle_id (id, vehicle_id, or vin). It is categorised as a Execute tool in the Tesla MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on wake_up? +

Register the Tesla MCP Server MCP server in PolicyLayer and add a rule for wake_up: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tesla MCP Server. Nothing to install.

What risk level is wake_up? +

wake_up is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit wake_up? +

Yes. Add a rate_limit block to the wake_up rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block wake_up completely? +

Set action: deny in the PolicyLayer policy for wake_up. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides wake_up? +

wake_up is provided by the Tesla MCP Server MCP server (sara3/tesla-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
