run_monte_carlo · Tradeblocks MCP: Risk & Policy

WHAT IT DOES

What run_monte_carlo does on Tradeblocks

AI agents invoke run_monte_carlo to trigger actions in Tradeblocks. 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 run_monte_carlo needs a policy

run_monte_carlo triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Verdict

run_monte_carlo Rate-limited

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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Tradeblocks, so you can run agents against it safely.

FAQ

Questions about run_monte_carlo

What does the run_monte_carlo tool do? +

Run Monte Carlo simulation to project future performance and calculate risk metrics. It is categorised as a Execute tool in the Tradeblocks MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_monte_carlo? +

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

What risk level is run_monte_carlo? +

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

Can I rate-limit run_monte_carlo? +

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

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

run_monte_carlo is provided by the Tradeblocks MCP server (tradeblocks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
