OptionsBell Options Flow

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."

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.
