The trade math
agents don’t reinvent.

Give your AI agent exact options, forex, risk and statistics, prediction-market, on-chain, and futures math via MCP, not hallucinated estimates. TradingCalc is the deterministic computation layer your agent calls for option Greeks, pip value, Sharpe and VaR, position size, liquidation price, funding cost, and PnL.

01WHY AGENTS NEED THIS

Why AI agents need exact calculations

When an LLM answers “what's my liquidation price at 10× leverage?”, it approximates. For a position at $83,000 BTC, the difference between “approximately $75,000” and the exact $75,155 could mean the difference between holding through a dip and getting liquidated on one.

AGENT WITHOUT MCP
Asks the LLM to calculate liquidation price. Gets a plausible number. May be 5–15% off. Error compounds across multi-step workflows.
AGENT WITH TRADINGCALC MCP
Calls workflow.run_liquidation_safety. Gets the exact number from a verified formula. Same inputs, same outputs.
