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.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
