Overview

AI-generated overview

Gives an assistant US options-flow and stock data such as unusual activity, gamma levels, implied volatility, and earnings.

What it does
OptionWhales is a remote MCP server that exposes US options flow and stock market data to an assistant. According to the registry description, it covers unusual options activity, gamma levels, implied volatility, and earnings. The manifest lists no individual tools, but mentions a register_free_key tool that agents can use to obtain a free API key.
When to use it
Worth adding when an assistant needs to look up US options-flow signals or related stock metrics, for example unusual activity, gamma levels, implied volatility, or earnings, while answering market questions.
Requirements
A remote streamable HTTP endpoint at api.optionwhales.io; nothing local to install. Authentication is optional for a small preview, and a free or Pro API key can be supplied in the X-API-Key header. The registry description also mentions OAuth sign-in.
Before you install
The server asks for an API key in the X-API-Key header; treat it as a secret and avoid exposing it. The registry description mentions OAuth sign-in, so review what account access is granted. Market data is third-party and may be delayed or incomplete; nothing in the input indicates trading or payment actions.
