AI agents invoke workflow.run_risk_reward to trigger processes or run actions in TradingCalc MCP — Crypto Futures Math. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
workflow.run_risk_reward can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Full risk:reward analysis — the single best tool when user describes a trade with entry, stop, and target. Calculates R:R ratio, position size, liquidation price, breakeven, and P&L at both stop and target. Returns a verdict: strong (3:1+) / good (2:1+) / marginal / poor. Use when user asks "is this trade worth taking?" or "what's my risk reward on this setup?".. It is categorised as a Execute tool in the TradingCalc MCP — Crypto Futures Math MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the TradingCalc MCP — Crypto Futures Math MCP server in PolicyLayer and add a rule for workflow.run_risk_reward: 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 TradingCalc MCP — Crypto Futures Math. Nothing to install.
workflow.run_risk_reward is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the workflow.run_risk_reward 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.
Set action: deny in the PolicyLayer policy for workflow.run_risk_reward. 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.
workflow.run_risk_reward is provided by the TradingCalc MCP — Crypto Futures Math MCP server (https://tradingcalc.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
