Quorel turns any public website into a structured, versioned dataset. Every nightly refresh is saved as a queryable version, so you see what changed, not just what's true today. Every dataset ships with an MCP server, so Claude or any agent can query, read, clean, and fix the data directly.

Hey Product Hunt,
Quorel turns any public website into a structured, versioned dataset. Describe the fields you want in plain English, it extracts them nightly, and keeps every past version queryable, so you can see what changed and when, not just what's true right now.
Here's a real version diff, not a mockup: 25 rows added, 78 removed, 312 modified between two versions of the same live dataset.

Every dataset also ships with an MCP server on every plan, including Free. That means Claude or any MCP-compatible agent can query it, clean it, and even fix bad rows, publishing the result as a new reversible version.

Would love feedback, especially from anyone building agent tools or data pipelines. What would you want Quorel to do that it doesn't yet?

Finally a way to stop scraping the same site every morning and guessing what's actually different. The MCP server piece is clever, my agent just fixed a typo in our pricing dataset without me writing a single line.

@substackpro Really glad to hear that, an agent fixing a typo through the MCP server is exactly the workflow I built this for. What are you using it on, is it your own dataset or one from the public library? Would love to hear more about your setup
