Why simulate_room_survival_time needs a policy

This tool executes a computational simulation whose effects (output survival time estimates) depend on the input arguments provided (player stats, enemy configuration, etc.). It does not merely read static data, nor does it modify game state irreversibly or move financial resources.

From the tool's definition The tool 'simulate_room_survival_time' runs a simulation that estimates player survival duration against enemies. The word 'simulate' indicates execution of code to model game scenarios with parameters that could vary based on input arguments.

POLICY

How to control simulate_room_survival_time

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Game Helper, and nothing reaches the server without passing your rules. This is the rule we recommend for simulate_room_survival_time:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "simulate_room_survival_time": {
      "limits": [
        {
          "counter": "simulate_room_survival_time_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

simulate_room_survival_time 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.

Create a free account and register Mcp Game Helper — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about simulate_room_survival_time

What does the simulate_room_survival_time tool do? +

Estimate how long the player survives vs a group of enemies. It is categorised as a Execute tool in the Mcp Game Helper MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on simulate_room_survival_time? +

Register the Mcp Game Helper MCP server in PolicyLayer and add a rule for simulate_room_survival_time: 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 Mcp Game Helper. Nothing to install.

What risk level is simulate_room_survival_time? +

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

Can I rate-limit simulate_room_survival_time? +

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

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

simulate_room_survival_time is provided by the Mcp Game Helper MCP server (xhulz/mcp-game-helper). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
