From the project's GitHub README.

OptionsBell MCP Server

Ask Claude (or any MCP client) about unusual options activity on 7,000+ US-listed stocks. The whole US options tape is rescanned every 5 minutes; this server exposes the unusual prints and the analytics derived from them.

Endpoint: https://optionsbell.com/mcp (Streamable HTTP)
Registry name: com.optionsbell/options-flow
Website: optionsbell.com
Setup guide: optionsbell.com/docs/mcp

This repository hosts the registry manifest and documentation for the hosted (remote) server. The server itself runs at optionsbell.com.

What you can ask

"What unusual put buying hit TSLA today?"
"Where has unusual flow shown up for 10+ consecutive days?"
"Which sectors is premium concentrating in this week?"
"Show me stocks with put IV rank above 0.8 - and pull the biggest prints on each."

Anonymous connections can list tools; calls return a friendly hint. Tool calls count 1:1 against your API rate limits (Pro: 30/min, 2,000/day).

Data notes

Coverage is unusual activity only - contracts that passed the unusual filter, not the full options tape. Derived analytics are aggregated from those prints (~75 trading days of history).
Premium values are estimates (last_price × volume × 100).
Market data, not investment advice.
