In the last few days I've dug up some work I was working on last year but never was able to ship due to perfectionism.
But with my new attitude, here it is: I also immediately got it in MCP-form so you can use it in Claude and Cursor as well.
Enable Claude / Cursor to know ANY API!! Video and links here: https://x.com/janwilmake/status/1903497808134496583
P.S. Expect bugs. Building in public. I've tested it with a few apis so far, and so far it worked really well as MCP every time.
P.P.S. It's all Open source! https://github.com/janwilmake/openapisearch and https://github.com/janwilmake/openapi-mcp-server
