Check if the player is currently in a vehicle.
AI agents call is_in_vehicle to retrieve information from GTAV-CLAUDE-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple state-query tool that reads the player's current vehicle status. It has no side effects, cannot modify game state, and poses minimal security risk even if misused by an AI agent. The worst outcome would be obtaining inaccurate information about player state, which cannot cause harm.
From the tool's definition Tool name 'is_in_vehicle' and description 'Check if the player is currently in a vehicle' indicate a query operation that retrieves the current state of the player without modifying any game data or triggering actions.
