## Moontower

Moontower positions itself as AI-powered volatility intelligence rather than a generic screener. Instead of reselling third-party data, it computes its own volatility surfaces, derives the downstream metrics itself, and renders them in a set of opinionated charts spanning a cockpit, dashboard, trade ideas and drill-down views. The result is a platform that speaks the language of professional vol traders while staying usable for individuals.

The headline feature is the Moontower Agent, an AI assistant that answers questions such as whether a name's volatility is cheap or rich into earnings, which stocks have the richest skew against their own history, or how to price a zero-cost collar. Answers are grounded in market data with sentence-level citations, and the team stresses that prompts and documents are never used to train models, with audit logs available for Enterprise. Structured workflows for income, defensive and collar strategies turn that context into trades.

For developers and quant workflows, Moontower runs a hosted MCP server. Adding it with one command gives Claude Code and other MCP clients 16 typed tools covering implied vol, skew, constant-maturity IV, option chains, trade ideas and cockpit statistics, authenticated via OAuth or an API key. Moontower reports 5,000+ traders, 500+ monitored assets, 52 proprietary charts and more than 100 million tokens processed per month.

**Pricing & Plans:** Moontower uses a freemium model with a free sign-up tier and paid plans for individuals and firms; enterprise features such as audit logs and the funding suite are available. The hosted MCP server is included on every plan at 2 credits per call. Exact prices are best confirmed on the site or via a demo.

- **Proprietary vol surfaces and charts:** 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.
- **AI agent with cited answers:** 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.
- **Trade workflows:** 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.
- **Hosted MCP server:** 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.
- **Cross-asset screening:** Screen across equities, ETFs, crypto and more for rich or cheap variance risk premium, IV rank and skew relative to each name's own history, while filtering by earnings dates and liquidity.

**Strengths:** Computes its own volatility surfaces rather than reselling third-party data.; AI answers come with sentence-level citations, which builds trust for trading decisions.; MCP server gives Claude Code and other agents direct, typed access to options data.; Covers multiple asset classes and workflows including income, defensive and collar strategies.

**Limitations:** Serious options analytics carry a learning curve for beginners.; Full desk-grade features and the funding suite are aimed at firms and may require a demo or higher-tier plan.; Output is strictly educational analytics, not investment advice.

## Options Chain

Options Chain is a lightweight Chrome extension built for traders who want fast answers without juggling tabs. When you select a stock ticker, the extension loads the current options chain from the Yahoo Finance API, so strikes, contracts and pricing sit right beside whatever you are already reading.

Beyond the raw chain, it layers in an OpenAI-generated company summary, giving a plain-language snapshot of the business behind the ticker. Charts accompany the options data so you can read structure and levels at a glance.

Lookup is flexible: search a symbol inside the extension, or simply let it detect a ticker when you run a Google search for a stock. The extension keeps your data private — the developer discloses that it does not sell user data or repurpose it outside the extension's core functionality. It is free to install from the Chrome Web Store and is aimed at quick research rather than full trading workflows.

**Pricing & Plans:** Options Chain is free to install and use from the Chrome Web Store. There is no advertised subscription; the extension leans on the Yahoo Finance and OpenAI APIs for its data and summaries.

- **Live options chain lookup:** Load the current options chain for any ticker (for example TSLA) directly from the Yahoo Finance API.
- **OpenAI-powered company summary:** Generate a quick company summary for the selected ticker using OpenAI's API, giving context alongside the contract data.
- **In-extension and Google ticker search:** Search for a ticker inside the extension or let it detect the symbol when you search Google for a stock.
- **Charts included:** View relevant options information with embedded charts for faster at-a-glance reading.

**Strengths:** Free to install with no subscription; Loads options chains instantly from Yahoo Finance data; Company summary adds context to raw contract data; Works both inside the extension and during Google stock searches

**Limitations:** Relies on Yahoo Finance and OpenAI APIs, so results depend on those services; Windows/Chrome-only distribution through the browser store; Small user base and modest feature set with no alerts or portfolio tools
