Plugs institutional risk analytics directly into Claude via the Model Context Protocol. Exposes 10 tools including VaR calculation, Monte Carlo simulation with configurable paths, historical stress testing, portfolio optimization, and options Greeks. Free tier gets you 7 tools and 20 positions per portfolio. Pro unlocks mean-variance optimization, 500-position portfolios, and 100k simulation paths. Runs as a local stdio process that talks to a Cloudflare Workers backend, which pulls real market data from Yahoo Finance and runs the math server-side. Useful when you need actual calculated risk metrics instead of LLM estimates, or when you're building portfolio analysis workflows that need to ground decisions in real numbers.
