ChatGPT MCP Integration

Flint has a remote MCP (Model Context Protocol) server that connects directly to ChatGPT. Once connected, you can create landing pages just by describing what you want - no app switching, no manual building required.

This integration allows ChatGPT to create, modify, and manage your Flint pages directly through conversation. Full MCP support with write and modify actions is currently available on ChatGPT Business, Enterprise, and Edu plans. Pro and Plus users can connect MCP servers with read and fetch permissions. Availability and permissions may change while this feature is in beta.

Follow these steps to connect Flint to ChatGPT through the MCP server:

1. Enable Developer Mode

In ChatGPT, open Settings, select Security and login, and turn on Developer mode. On managed Business, Enterprise, or Edu workspaces, an admin may first need to grant access. Depending on your workspace, the setting may appear under Settings > Apps > Advanced Settings or while creating an app from Workspace settings > Apps.

2. Create the Flint App

Go to chatgpt.com/plugins, select the plus button, and create a developer-mode app. Name it Flint, then enter the remote MCP server URL:

https://mcp.tryflint.com/mcp

3. Authenticate and Scan Tools

Choose OAuth authentication, then select Scan Tools. Sign in to your Flint account when prompted and wait for ChatGPT to finish discovering the available tools. Select Create to save the app.

4. Start Building

Open a new ChatGPT conversation. Choose Developer mode from the plus menu, select Flint for the conversation, and describe the page you want to create.

Copy this value when setting up the integration:

Once connected, you can ask ChatGPT to build landing pages for any campaign, ICP, or keyword. Describe the audience, the offer, and the tone - ChatGPT handles the rest and builds the page directly in Flint, ready to review.

Example Prompt

Generate a personalized account page targeting OpenAI. Tailor the messaging to address their specific industry needs.

ChatGPT will use Flint to generate and create the page, which you can then preview and publish. ChatGPT may ask you to approve tool calls before it makes changes.

The Flint MCP server exposes four tools that ChatGPT can use:

run_background_agent

Start a background AI agent on a Flint site. The agent executes a prompt to modify your website.

Returns a workflow ID that can be used to check status.

check_background_agent_status

Check the status of a previously started background agent.

Returns the current status, phase, and output when completed.

list_sites

Lists all Flint sites accessible to your account. No parameters required.

Returns a list of sites with their name, site ID, organization ID, and organization name. This is useful for discovering your site IDs without leaving the conversation - just ask ChatGPT "what sites do I have?" and it will look them up for you.

publish_site

Deploys a Flint site to production.

Resolves the latest changes on the staging branch and triggers a production deployment. Ask ChatGPT to make changes with run_background_agent, review the results, then ask ChatGPT to publish when you're ready.
