Posted previously about the price scraping site I pulled together that matches meat from a variety of online butchers to an internal shared taxonomy to make it easier to see what's actually a good price vs. a temporary price fluctuation.

I've now got over a year of data so there are some interesting patterns appearing in various product offerings (some of it seasonal, some of it as expected appears to be reactionary to price changes on competitors).

I just wanted to get the best price for meat that I enjoy smoking on my Kamado, but it got a little out of hand, so now there's a full on basket comparison (get the cheapest basket in one shop for your chosen products) and grouped cut analysis over time (to see how price is changing and if it's genuinely a good price right now).

Because it seems like everyone's doing it these days (and UI is so painful to craft and keep up to date), added an MCP server so you can ask your AI about the data directly instead of clicking around the site. It's read only and free.

Things you can ask it: - Search products across every butcher we track - Browse a cut and see the cheapest and dearest - Price per kg plus how many shops stock it - Current best deals (cheapest supplier for a cut vs what it normally goes for) - Compare a basket of cuts across suppliers to see who works out cheapest overall - price history and trend for a cut

If you fancy giving it a go (and would like to share feedback!)

Setup:

Claude web:

- Settings, Connectors, add a custom connector. - URL is https://meat.offer-spider.com/api/mcp - Leave the OAuth client ID and secret blank, it registers itself. - Then you sign in with your email and hit approve.

Anything that lets you set a header:

- go to https://meat.offer-spider.com/register your email, and you get an API key. - Send it as Authorization: Bearer <key>. - verify

Also works with Antigravity and ChatGPT/Codex if that's your thing.

It's rate limited and capped so nobody can pull the whole catalogue, but for normal questions it's more than enough.

Happy to take requests for more tools or feedback on the setup. Getting OAuth working for MCP was more fiddly than it should be, so if you hit any snags adding it, let me know.
