Use MyGroceryPal in ChatGPT and Claude
Last updated 7 November 2026.
Add MyGroceryPal to your AI assistant and it can answer grocery questions with real UK supermarket prices, checked every day across Tesco, Sainsbury's, ASDA, Aldi, Morrisons, Co-op, Waitrose, Iceland, B&M, Boots, Superdrug, Savers and Ocado.
What you can ask
- "Where is Lurpak slightly salted butter 500g cheapest?"
- "Is £4.80 a good price for Lurpak 500g?"
- "Which supermarket is cheapest for Heinz beans, semi-skimmed milk and Hovis bread?"
- "Tell me when Cadbury chocolate goes on offer."
Searching and price history work straight away. Comparing a basket and setting a deal alert ask you to connect a free MyGroceryPal account, so the alert reaches you by push notification or email like any other.
Add it to Claude
- Open Customize, then Connectors, and choose Add custom connector.
-
Name it MyGroceryPal, paste this address and continue:
https://mygrocerypal.co.uk/api/mcp - Under Authentication, Claude picks No sign-in because searching works without an account. Choose Sign in when needed instead.
-
Under OAuth client, choose Use your own OAuth client and
paste this client ID:
tpc_n497TrbFJS1DT86nstehra. Leave the secret empty, then add the connector.
Claude asks you to sign in the first time you compare a basket or set an alert. If your Claude shows a single screen with Advanced settings instead, paste the same client ID there.
Add it to ChatGPT
MyGroceryPal is on its way to ChatGPT's app directory. Once it is listed, you will find it there by name.
Other assistants and tools
Any app that supports remote MCP servers with OAuth can use the
same address and client ID. The server is listed in the official
MCP Registry as
uk.co.mygrocerypal/grocery-prices.
What it shares
Your assistant sends us only what it needs to answer: the product you searched for, or the products in your basket. We do not keep your searches. Answers carry prices and links back to MyGroceryPal, never product photos or descriptions. The privacy policy has the detail, and you can disconnect in your assistant's settings at any time.
