- We keep the first three digits of the ZIP, not the full ZIP, and no product names you typed.
- Sign-in tokens and keys are stored as one-way hashes. Disconnect any app from agent settings.
- The connection is read-only. It can give you a link to buy credits, but only you approve the payment, on Stripe. Endless never sees your card number.

FAQ
Questions
What is the Endless MCP server?
A remote MCP (Model Context Protocol) server at https://endless.page/mcp. It gives an AI agent three read-only tools backed by Endless price data: price history, store-by-store prices near a ZIP, and the top clearance near a ZIP. Two more tools, credit_balance and buy_credits, let the agent check and top up its credits.
Which AI apps can use it?
Claude (including Duet), ChatGPT (including Dots), Meta Muse, and any other app that connects to a remote MCP server over HTTP with OAuth or a bearer key.
Which retailers does it cover?
Price history covers 23 retailers, including Home Depot, Lowe's, Walmart, Target, Best Buy, Costco, Sam's Club, Macy's, Nordstrom, Nordstrom Rack, Dick's Sporting Goods, Academy, Newegg, Gap and J.Crew. Store-by-store prices cover Home Depot, Lowe's, Costco and Sam's Club. Clearance near a ZIP covers Home Depot, Lowe's, Best Buy and Sam's Club.
How much does it cost?
Lookups cost credits: price history 1 credit, store prices near a ZIP 2, clearance near a ZIP 3. Credit packs are 500 credits for $4.99 or 3,000 credits for $19.99, one-time. The Agent plan is $4.99 a month for 1,000 credits. Endless Basic ($9.99/mo) includes 500 credits a month, Pro ($19.99/mo) 3,000 and Premium ($39.99/mo) 10,000. Every account gets 25 free credits the first time it connects an agent.
Can my agent buy credits by itself?
Yes, with your approval. When credits run out, the agent calls buy_credits and gets a secure endless.page payment link. You open it and approve a one-time payment on Stripe (card or Link). The credits land within seconds and the agent carries on in the same conversation. Nothing is ever charged without you approving it.
Do I need an Endless account first?
No. When you connect, the sign-in page lets you buy a credit pack instead of signing in. Endless makes your account from the email you pay with and connects your agent in the same step. You can set a password later with Forgot password.
What happens when credits run out?
Your plan's monthly credits are used first, then bought credits. When both are used up, the agent is told how to buy more (the tool name and price), and plan credits refill at the start of the next period. There is also a limit of 30 calls a minute per connection.
Is the live price-error feed included?
No. The live price-error feed, penny lists, saved-store alerts and the full catalog browser stay in the main Endless product. Agents get capped answers to specific questions, not a bulk export.
Can the agent see my account or spend my money?
It cannot see your saved stores, watchlist or billing, and it cannot place retail orders. It can give you a link to buy Endless credits, but only you can approve that payment, on Stripe. Endless never sees your card number. Product links open the retailer page so you decide.
How current are the prices?
Every store price and deal in a result carries the time Endless last saw it. In-store prices and stock change daily, so check the shelf or the retailer app before you drive.
What does Endless keep about my agent calls?
One record per call: your account, the app, the tool, the retailer, the first three digits of the ZIP, how the item was identified, the result count and the response time. Never your conversation, full ZIP codes or product names you typed. For a credit purchase we keep the pack, the amount and the app that asked; the card itself stays with Stripe.
