act · GTAV-CLAUDE- MCP: Risk & Policy

WHAT IT DOES

What act does on GTAV-CLAUDE-MCP

AI agents invoke act 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 act needs a policy

The description is empty, lowering confidence. However, given the server's capabilities (executing game natives, reading/writing memory, spawning entities) and sibling tools like call_native, call_function, and cache_visual_offsets, 'act' most likely triggers some form of in-game action or execution. The server's ability to read/write memory and call arbitrary game functions places this at high severity if misused.

From the tool's definition Tool name 'act' with empty description; server context includes spawning vehicles, changing weather/time, calling game natives, and reading/writing memory

Verdict

act Rate-limited

act 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.

FAQ

Questions about act

What does the act tool do? +

act. It is categorised as a Execute tool in the GTAV-CLAUDE-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on act? +

Register the GTAV-CLAUDE- MCP server in PolicyLayer and add a rule for act: 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 GTAV-CLAUDE-MCP. Nothing to install.

What risk level is act? +

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

Can I rate-limit act? +

Yes. Add a rate_limit block to the act 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 act completely? +

Set action: deny in the PolicyLayer policy for act. 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 act? +

act is provided by the GTAV-CLAUDE- MCP server (tabbedscamper/gtav-claude-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
