Formgong MCP: let the agent wire a contact form that actually delivers

Showcase Built for Cursor

Hi all. Disclosure first: we build Formgong, a hosted form backend, and this is our MCP server.

The problem we kept seeing: Cursor (or Lovable, v0, Bolt) generates a nice contact form, and it posts nowhere. Or it needs an API route + Resend + env vars that nobody set up. So we gave the agent a way to set up the backend part itself.

What it is

  • Remote MCP server: formgong.com/mcp (Streamable HTTP, stateless, JSON responses)
  • Auth: a personal API token, Authorization: Bearer fgp_…, created in Dashboard → Account → API tokens. Tokens are scoped (forms:read, forms:write, submissions:read), can expire and can be revoked.
  • initialize, ping and tools/list work without a token, so you can look at the tools before signing up.

Tools

  • list_forms: your forms with id, name and public access key
  • create_form: name + notify email, returns the access key
  • get_form_snippet: html, react or next code for one form, with the access key, the _lang field and the honeypot already filled in
  • list_recent_submissions: read-only and opt-in (separate scope); no IP or user agent; spam excluded by default

Cursor setup (~/.cursor/mcp.json or .cursor/mcp.json):

{
  "mcpServers": {
    "formgong": {
      "url": "https://formgong.com/mcp",
      "headers": { "Authorization": "Bearer ${env:FORMGONG_TOKEN}" }
    }
  }
}

Then something like: “Create a Formgong form called ‘Contact – acme.com’ and add it to the contact page as a React component.”

Where the submissions go: email and Telegram (Telegram is on the free plan too), plus signed JSON webhooks if you want n8n / Make / Zapier. Data is stored in the EU.

Limits, honestly

  • No OAuth yet. Clients that only accept OAuth connectors need the mcp-remote bridge.
  • create_form is limited to 10 new forms per hour. Each token gets 60 requests a minute.
  • It doesn’t build forms visually. It creates the backend and gives the agent code to paste.

Free plan: 300 submissions a month. Paid plans start at $5/month (as of Oct 2026).

I’d really like feedback on the tool design: are four tools the right cut, and what would you want the agent to be able to do that it can’t?

Small update: we added a few things for people building with agents.

There’s also a free read-only form checker that tells you why a form on a live page might not deliver. Feedback welcome.
