WHAT IT DOES

What runtime_freeze does on Godot

AI agents invoke runtime_freeze to trigger actions in Godot. 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.

RISK

Why runtime_freeze is rated High

Triggers an external operation on the running game process, pausing execution.

RECOMMENDED RULE

The rule that runs runtime_freeze safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For runtime_freeze, this is the rule to start with:

runtime_freeze Rate-limited

runtime_freeze 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.

}

The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every runtime_freeze call is checked against it from then on.

FAQ

Questions about runtime_freeze

What does the runtime_freeze tool do? +

Pause (freeze) the running game. It is categorised as a Execute tool in the Godot MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on runtime_freeze? +

Register the Godot MCP server in PolicyLayer and add a rule for runtime_freeze: 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 Godot. Nothing to install.

What risk level is runtime_freeze? +

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

Can I rate-limit runtime_freeze? +

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

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

runtime_freeze is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
