I left my job to work on my side project (MCP-B: https://news.ycombinator.com/item?id=44515403) full time. I set out with the goal of making the ability to vibecode a webMCP server for your website and inject it via userscript.

While building that, I basically wrote a modern version of Tampermonkey with its own marketplace built in. So you can vibe code any userscript and publish it to the marketplace all within the extension.

The automation stuff is still the core value-prop, but this is a fun bonus feature while I work on solidifying the automation features.

I'm writing a HN post for it. Excited to show everyone in a couple weeks here.
