Show HN: FormProxy – form back end for AI-generated pages – MCP Ready

I kept running into the same problem building with AI code tools: the generated HTML looks great, but the <form> has no backend. You either reach for Formspree, write a serverless function, or ship it broken.

FormProxy wires it up in one step. Drop a page URL, get a POST endpoint, and submissions route to Slack, webhooks, or Google Sheets. (Google Sheets is currently unreliable — waiting on Google's OAuth app review, which is taking longer than expected. Webhook and Slack are production-ready.)

The angle I'm most interested in: there's an MCP skill so LLMs can provision the form endpoint themselves during code generation. Claude or GPT-4 can call FormProxy mid-session, inject the action URL into the HTML it's writing, and the page ships with a working form — no manual wiring.

Happy to be challenged on: why not just Formspree, how the MCP skill actually works in practice, and what the right pricing model is for this. I've been going back and forth on per-submission vs. per-endpoint.
