Deal.ai is in Claude's connectors directory. Connect it once and Claude can compare every store's price for the same item, look up its price history, check whether a deal is real, ask Deal.ai's shopping agent for picks, and watch prices for you.
It's free with a Deal.ai account, and works in Claude on the web, Claude Desktop, Claude's mobile apps and Claude Code.
Server address (Streamable HTTP, OAuth sign-in)
https://deal.ai/mcpClaude's menus move from time to time; if a name below differs, look for Connectors in Claude's settings.
In Claude on the web or Claude Desktop, open Customize, then Connectors (some versions have it under Settings). Browse the directory, search for Deal.ai and choose Connect.
On a Team or Enterprise plan, an owner adds connectors for the organization first; then each member connects their own Deal.ai account.
On the same Connectors page, choose to add a custom connector, name it Deal.ai and paste the server address above. Leave the sign-in settings as Claude suggests: Deal.ai signs you in with OAuth, with no client ID or secret to enter.
Claude's Free plan allows one custom connector, so the directory is the simpler way there.
Add the server from a terminal:
claude mcp add --transport http deal-ai https://deal.ai/mcp
That adds it for the project you're in. To have it in every project, add --scope user:
claude mcp add --transport http --scope user deal-ai https://deal.ai/mcp
Then type /mcp in Claude Code, choose deal-ai and sign in to Deal.ai in the browser it opens. Connectors you've added on claude.ai can also appear in Claude Code when you're signed in with the same Claude account.
Connectors you connect on the web or in Claude Desktop are there in Claude's iOS and Android apps the next time you sign in. Set Deal.ai up on a computer first; then ask from your phone in a store, for example with a product's name and the price on its shelf tag.
Claude never sees your password: it gets a key to your Deal.ai account that renews itself while you use it and lapses after 90 days unused. Your account page lists it under Connected apps, with when it was connected and last used; Disconnect ends it at once. In a chat, you can turn Deal.ai on or off for that conversation from the + menu, under Connectors.
Name Deal.ai in the request the first time, so Claude knows to use it. Each answer links to the Deal.ai page behind it and to each store.
“Use Deal.ai to find the best robot vacuum under $400 for a home with two dogs, then explain the trade-offs between its picks.”
Answered by ask_deal_ai and get_deal_ai_answer
Deal.ai's shopping agent researches the request, which takes one to three minutes; Claude checks back for the answer. It comes back with the agent's written answer and up to six picks, each with why it was picked, its best price from a store, when that price was seen, its rating, and links to its Deal.ai page and the store. Claude can then weigh the picks with you, and follow-ups such as “only bagless ones” continue the same search.
“I'm setting up a home office. Look up the Herman Miller Aeron and the Dell U2724D on Deal.ai and put every store's price in a table.”
Answered by search_products and get_product_prices
For each product, every store's current price Deal.ai has, cheapest first (up to 15), with shipping, condition, whether it's in stock, the date each price was seen and a link to buy at that store. Listings by marketplace sellers are labelled as such and never called the best price.
“What's the lowest price Deal.ai has tracked for the Dyson V15 Detect? Is now a good time to buy?”
Answered by get_product_prices
Along with today's prices, the product's price history: the lowest price Deal.ai has tracked, with the day and the store, the highest, how many stores it has tracked, and its daily lowest prices over the last 30 days. Claude reads the trend; Deal.ai doesn't forecast prices.
“Is $249 a good price for this? Check it with Deal.ai: (paste a link to the product at any store)”
Answered by check_deal and get_deal_check
A deal check finds the exact item, new, at every big US store at the same moment, usually in 20 to 70 seconds. The verdict says whether it's cheaper elsewhere (where, and by how much), as low as any store, or sold only by that store; then each store's price with a link, whether the store's “was” price is being charged anywhere, and a result page on deal.ai you can share.
“Compare the Breville Bambino Plus, the De'Longhi Dedica and the Gaggia Classic Pro on Deal.ai: specs, ratings and where each is cheapest.”
Answered by search_products and compare_products
Two to four products side by side: the specs they share, row by row, each one's rating and its best price from a store with when it was seen and a link, and Deal.ai's own comparison pages for the pair when it has them.
“Watch the Aeron for price drops, and remind me what else I'm watching on Deal.ai.”
Answered by watch_price and list_watched
The product is saved to your Deal.ai wish list, which e-mails you when its price drops. The answer gives its best price now and whether your price-drop e-mails are on, then lists what you're watching with each product's price now and when you saved it.
