MCP Server

Build forms inside
your AI chat.

Brieform is an AI-native form builder with a full MCP server. Connect once, then create, publish, and read form responses by prompt — in Claude, ChatGPT, Cursor, or any MCP client.

Two ways to use Brieform in AI

Both modes use the same MCP server URL.

MCP

All clients

Text automation

Create and manage forms by prompt. The AI calls the right tool and returns a confirmation with a preview link. Works in Claude, ChatGPT, Cursor, VS Code, Le Chat, and any MCP-compatible client.

MCP-App

Claude.ai

Visual preview

In clients that support the MCP Apps standard, Brieform renders your form as a live widget directly inside the chat. See the real form, not a description of it — no tab-switching required.

Server URL

Paste this URL when adding a custom MCP connector in any client.

https://brieform.app//api/mcp/mcp

Transport: Streamable HTTP (MCP 2025-03-26). SSE-only clients may not be compatible.

Prerequisites

01

A Brieform account

Free. No credit card required. Sign up at brieform.app/register.

02

An MCP-compatible client

Claude, ChatGPT, Cursor, VS Code with Copilot, Le Chat, Perplexity, Claude Code, or any client that supports Streamable HTTP transport.

Connecting and authorizing

OAuth 2.1 — recommended

For chat clients. On first use, your client opens a Brieform authorization page in a browser window. Log in or sign up (free), then click Allow. The token refreshes automatically — you never log in again.

To revoke access, go to Dashboard → Account → AI Connected Apps and click Revoke next to the client. Access is cut immediately.

API key — for scripts

For CI pipelines, scripts, and clients without OAuth support. Generate a bf_... key in Dashboard → Account and pass it as a Bearer token in the Authorization header.

Example prompts

Copy any of these into your AI client after connecting Brieform.

Create a contact form with name, email, and message.

Brieform creates a three-field draft and returns a preview link. You can publish it right from the same conversation.

Apply a midnight blue theme with rounded corners to this form.

The AI calls set_form_theme with a custom color and border-radius. The preview link updates instantly.

Turn it into a multi-step form, one question per screen.

update_form rewrites the step structure. Each field gets its own screen; navigation buttons are added automatically.

Show the company field only if the user selects professional use.

Conditional logic is added to the field definition. The form hides or shows the field based on the trigger answer.

Publish the form and give me the link.

publish_form makes the form live and returns the public URL, embed snippet, and a QR code.

How many responses did I get this week, and what do they say?

get_responses fetches recent submissions and the AI summarizes them. No spreadsheet export needed.
