Deal.ai's MCP server lets Claude, ChatGPT, Cursor and other assistants compare every store's price for the same item, look up price history, check whether a deal is real, and watch prices for you. It's free with a Deal.ai account.
Server address (Streamable HTTP)

}Cursor, VS Code and other clients open Deal.ai's sign-in in your browser the first time. Menu names change from time to time; any client that supports remote MCP servers over Streamable HTTP, with OAuth sign-in, works. Disconnect an app any time from your account.
