Your Next Customer Won't Fill Out Your Form. Their AI Agent Will.

Cube Forms launched today (free): one link for people and their AI agents.

• People see a normal web form.
• Agents read the same form as plain text (Markdown or JSON) and send their answers straight in, over HTTP or MCP.
• No HTTP access? The agent hands the person a prefilled link to check and submit.

The examples: event sign-ups, talk-to-sales, client intake, job applications, feedback.

The rules Cube gives agents: only use what the person provided, ask for anything missing, and never tick a consent box without asking.

The catch: it’s day one. No independent security or privacy review yet. Test it with a throwaway form and a test webhook before you put real clients on it:

1. Check the webhook signature (Cube-Signature)
2. Try duplicate and junk submissions
3. Make sure you can tell which person an agent is acting for
