Description, as the server wrote it
Ask one whole sports betting price question in plain English, the way a person would: which book pays the most for a bet, hedge math on a ticket, a parlay price, a game's board, a past result or how a line has moved. Returns a plain-sentence answer, the time the prices were scanned and a link to the matching page on theoddsgap.com. When a question could mean more than one game, it returns the choices as plain text to ask again with. Prices may have moved since the scan. Information only: it places no bets and gives no picks.

9 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
