Here’s how to connect Flax to ChatGPT today, without waiting for a public Plugins Directory listing.

ChatGPT Pro can connect Flax for read-only help. It can review your website and suggest improvements, but it cannot edit your site. Business, Enterprise, and Edu workspaces can use full MCP tools, including editing, when the workspace allows them.

In ChatGPT on the web, open Plugins. Choose Personal, then Add, then Create MCP App.

Give the app a name you will recognize, such as Flax Sites. If you already have a Flax personal app, use a distinct name such as Flax Sites Early Access.

Paste the Flax server address into the Server URL box: https://agents.flaxsites.com/mcp

Leave OAuth selected. Check that the address is correct, then confirm that you trust Flax. Choose Create.

ChatGPT will open a Flax sign-in page. Sign in to your Flax account, choose the website you want to connect, and approve access. Wait for ChatGPT to finish connecting.

Start a new ChatGPT conversation. Open the tools menu and select the Flax app name you chose. Try asking: “List the Flax sites I connected to this account.” You can then ask ChatGPT to review a published site.

On Pro, Flax can read your website and ChatGPT can suggest improvements. To use editing tools in ChatGPT, use a Business, Enterprise, or Edu workspace with full MCP access.

If ChatGPT says it cannot open a site, check that the site is published and that its address opens in your browser, then try again.

If you can’t find Create MCP App, open Settings, Apps, Advanced Settings, and turn on Developer Mode. Workspace settings may be managed by an administrator.
