set_handling · GTAV-CLAUDE- MCP: Risk & Policy

WHAT IT DOES

What set_handling does on GTAV-CLAUDE-MCP

AI agents use set_handling to create or update resources in GTAV-CLAUDE-MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GTAV-CLAUDE-MCP environment.

WHY IT NEEDS A POLICY

Why set_handling needs a policy

This tool modifies vehicle handling properties in real-time within the game, which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), or involve financial transactions (Financial). While it could affect gameplay significantly, the modification is reversible by simply changing the value back.

From the tool's definition Tool name 'set_handling' combined with description 'Write a live CHandlingData float on the player's vehicle' explicitly indicates writing/modifying game state. The example 'initial_drive_force for power' shows it modifies vehicle physics parameters.

set_handling Rate-limited

set_handling stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

What risk level is set_handling? +

set_handling is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_handling? +
