i added MCP support to my SaaS in an afternoon. here's the whole thing.

I built Imagcon because I kept needing it. PWA icon generator — describe what you want, get all 19 sizes back plus splash screens and a manifest.json. every app I ship needs a fresh icon set and I got tired of doing it manually.

a few weeks ago I'm in the terminal with Claude Code working on something, I need icons, and I'm about to open a browser tab to do it. which means: describe the icon, wait for it to render, download the ZIP, drag the files into the project. while I'm already in a session where I could just say what I want.

so I asked Claude: is there a way to make this callable from inside the terminal, without leaving the editor?

MCP came back as the answer. I said let's build it. we went back and forth for an afternoon, hit one URL gotcha that cost me a solid hour, and by the end it was packaged and installable with one command. this is that whole afternoon.
