What run_monte_carlo does on RealVest Real Estate MCP Server

AI agents invoke run_monte_carlo to trigger actions in RealVest Real Estate MCP Server. 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 run_monte_carlo needs a policy

This tool executes a complex probabilistic simulation whose output depends entirely on input parameters (asset allocation, return distributions, volatility assumptions, etc.).

From the tool's definition Tool name 'run_monte_carlo' and description 'Run Monte Carlo simulation to assess investment risk and return probabilities' indicate execution of a computational simulation with multiple iterations.

Documented attack patterns abuse exactly the kind of access run_monte_carlo gives an agent:

How to control run_monte_carlo

PolicyLayer is an MCP gateway — it sits between your AI agents and RealVest Real Estate MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for run_monte_carlo:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "run_monte_carlo": {
      "limits": [
        {
          "counter": "run_monte_carlo_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

run_monte_carlo 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.
