set_weather · GTAV-CLAUDE- MCP: Risk & Policy

WHAT IT DOES

What set_weather does on GTAV-CLAUDE-MCP

AI agents invoke set_weather to trigger actions in GTAV-CLAUDE-MCP. 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 set_weather needs a policy

This tool modifies the in-game environment by triggering a weather change in GTA V. It has no effect outside the game process, no data is permanently stored or deleted, and no financial transaction occurs. It is an Execute-class action because it triggers an external operation (game native call) whose effects depend on the argument passed, with low blast radius since it only affects the weather state in a video game.

From the tool's definition 'Set weather instantly: CLEAR, EXTRASUNNY, CLOUDS, OVERCAST, RAIN, THUNDER, CLEARING, SMOG, FOGGY, SNOW, BLIZZARD, XMAS, HALLOWEEN' — triggers an external game-state change in GTA V
