Compute trading math with exact numbers instead of estimates, through TradingCalc's MCP tools. Options (Black-Scholes price and Greeks, payoff and breakeven, covered call, implied volatility), forex (position size, pip value, margin, swap, currency conversion, correlation), risk statistics (VaR, Sharpe ratio, Kelly, GARCH, tearsheet) and crypto futures (PnL, liquidation price, breakeven, funding cost). Use whenever a question needs a number a person might act on.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TradingCalc: deterministic trading math ## What this skill does Gives you exact answers to trading math questions instead of a language-model estimate. The TradingCalc MCP server exposes deterministic tools (the current list and count are on tradingcalc.io and in tools/list) across options, forex, risk statistics, crypto futures, on-chain token checks and prediction markets. The same inputs always return the same outputs, and the core calculators are checked against canonical test vectors on a public page (`https://tradingcalc.io/verify`). Do not work out a position size, a liquidation price, an option value or a Sharpe ratio yourself and present it as authoritative. A small arithmetic slip here is real financial risk for whoever acts on it. Call the tool. ## When to use it Options - "What is this option worth?" (spot, strike, days, volatility) : `workflow.run_black_scholes` - "Is this Deribit option fairly priced?" : `workflow.run_black_scholes_live` - "What does my call or put pay off at price X, and where is breakeven?" : `workflow.run_options_payoff` - "What yield do I get selling covered calls?" : `workflow.run_covered_call_protective_put` …

How to install
mdr add skalinin909/tradingcalc-mcp/tradingcalc@sha256:05d00944d56bc86bThe line at the top of this page pins the label git:20261101.c73675b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
