Moontower is AI-powered volatility intelligence for traders, desks and firms. It computes its own options volatility surfaces and presents them through a set of proprietary charts, adds an AI agent that reasons over that market data, and exposes a hosted MCP server so tools like Claude Code can query volatility, skew, option chains and trade ideas directly.
Moontower computes its own volatility surfaces, derives downstream metrics and presents them in 52 proprietary charts covering a live dashboard, cockpit, trade ideas and drill-down views.
The Moontower Agent answers questions like whether NVDA vol is cheap into earnings, grounding every claim with sentence-level citations from market data, research or your firm's own knowledge base.
Workflow templates for income (covered calls, cash-secured puts), defensive defined-downside exposure and collars including zero-cost collars map market context to concrete structures.
A hosted MCP server exposes 16 typed tools — implied vol, skew, constant-maturity IV, option chains, trade ideas and cockpit statistics — to Claude Code and other MCP clients over HTTP.
