preload_model · GTAV-CLAUDE- MCP: Risk & Policy

WHAT IT DOES

What preload_model does on GTAV-CLAUDE-MCP

AI agents invoke preload_model 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 preload_model needs a policy

Preloading a model initiates an external operation within the GTA V game engine (streaming/loading assets into memory). It doesn't read data for the caller, doesn't write persistent data, and doesn't destroy anything — it triggers a side-effecting engine call. The blast radius is low since it only affects game memory/streaming state temporarily.

From the tool's definition 'Preload a model so a later spawn is instant (avoids the streaming lag)' — triggers an external game operation to load assets into memory

Verdict

preload_model Rate-limited

preload_model 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 preload_model

What does the preload_model tool do? +

Preload a model so a later spawn is instant (avoids the streaming lag). wait=False to fire-and-forget. 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 preload_model? +

Register the GTAV-CLAUDE- MCP server in PolicyLayer and add a rule for preload_model: 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 preload_model? +

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

Can I rate-limit preload_model? +

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

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

preload_model 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.
