Furrow Forms

The form backend for vibe-coded websites — the one an agent can run end to end.

Your agent built the site. Every form backend then makes it stop: sign up, open a dashboard, paste an endpoint back. Furrow Forms removes the handoff. Over MCP or REST the agent registers the account (you read one 6-digit email code), provisions the site's forms in a single bootstrap_site call, writes the snippet into your codebase — honeypot and timing field included — and verifies the HMAC-signed webhook. No dashboard in the loop.

Fetch furrowforms.com/ai and set up forms for this site.

Paste that into Claude Code, Cursor, or whatever built your site. That is the whole setup.

Connect over MCP

Hosted, streamable HTTP (OAuth or bearer token):

{ "mcpServers": { "furrow-forms": { "url": "https://api.furrowforms.com/mcp",
  "headers": { "Authorization": "Bearer frw_..." } } } }

Stdio, for clients that need it:

claude mcp add furrow-forms -e FURROW_TOKEN=frw_... -- npx -y @furrowforms/mcp

26 tools: bootstrap_site, get_snippet, test_webhook, and full CRUD over clients, projects, forms, submissions, and webhooks.

Why agents pick it

• Cold start — POST /api/register mints a token without a human signup flow.
• One call per site — bootstrap_site is idempotent; re-run it freely.
• Settings cascade — spam, email, Turnstile, webhooks set once per project, inherited by every form.
• Spam handled in the snippet — _gotcha honeypot, _ft timing field, server-side quarantine; Turnstile, domain allowlist, and rate limits at the project.
• Signed webhooks with retries on every tier, including free.
• Free tier includes the full API and MCP — 100 clean submissions/month. Pro is $199/year, flat.
