Refresh the list of Tesla vehicles from the API.
AI agents call refresh_vehicles to retrieve information from Tesla MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or refreshes vehicle list metadata from the Tesla Fleet API. It is a read-only operation with no side effects on vehicles or user data. While it connects to Tesla infrastructure, the operation itself only queries and caches information. Severity is low because misuse would only result in stale or repeated data retrieval, not vehicle control, financial impact, or data destruction.
From the tool's definition Tool name 'refresh_vehicles' and description 'Refresh the list of Tesla vehicles from the API' indicate a query/retrieval operation that fetches or updates cached data without modifying vehicle state or data.

Register the Tesla MCP Server MCP server in PolicyLayer and add a rule for refresh_vehicles: 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.
refresh_vehicles is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the refresh_vehicles 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.
Set action: deny in the PolicyLayer policy for refresh_vehicles. 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.
refresh_vehicles 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.
