AI agents call workflow.run_liquidation_safety to retrieve information from TradingCalc MCP — Crypto Futures Math without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though workflow.run_liquidation_safety only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Calculate the liquidation price for an isolated-margin futures position. Use when user asks "where will I get liquidated?" or "how close is my liq price?". Returns: liquidationPrice, distancePct (how far from entry).. It is categorised as a Read tool in the TradingCalc MCP — Crypto Futures Math MCP Server, which means it retrieves data without modifying state.
Register the TradingCalc MCP — Crypto Futures Math MCP server in PolicyLayer and add a rule for workflow.run_liquidation_safety: 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_liquidation_safety is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the workflow.run_liquidation_safety 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_liquidation_safety. 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_liquidation_safety 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.
