Use TypeUI with Codex

Follow this guide to connect Codex to TypeUI for building and refining UI.

Open Codex

Open the project you want Codex to work on.

Add TypeUI to Codex

Add the TypeUI MCP server with the Codex CLI:

Run in terminal
codex mcp add typeui --url https://mcp.typeui.sh/mcp

Verify it is configured:

Run in terminal
codex mcp list

Sign in with TypeUI if Codex asks you to authorize the connection.

Create a draft

Start from a theme, a markdown ZIP, or a Figma import. TypeUI creates an editable draft design system in your workspace.

Review the markdown

Open View markdown source files and review them before publishing.

Files to review

The main entry file. It tells AI tools how to use this design system and where to look next.Logo and brand asset guidance. Colors, typography, and spacing stay in their own files.Color tokens and usage guidance for brand, surfaces, text, borders, and states.Font families, sizes, weights, line heights, headings, labels, and body text rules.Spacing, grids, containers, responsive behavior, and layout structure rules.Button sizes, variants, states, icon spacing, focus behavior, and accessibility rules.+14 more

Edit the source files

Adjust the markdown when you need clearer rules, stronger component guidance, or product-specific language. After publishing, TypeUI MCP uses your saved edits when it helps your AI tool build UI.

Publish for MCP

Publish when ready so your MCP-connected AI tool can use it.

Start building UI

Build me a landing page.

Tell Codex what to build. TypeUI helps it choose the right style and layout.

Review and refine

Run your app and review the page. Ask Codex for targeted improvements:

I don't like this pricing section, give me more variations.

TypeUI will now create three pricing variations so you can compare different layouts before choosing one.

After you choose a direction, tell Codex which one to use:

I like the comparison one. Let's use it.

Once Codex is connected to TypeUI MCP, you can keep working in the same flow: choose a design system, ask for the interface you need, review the generated variations, and tell Codex which direction to continue with.
