Create ads from the AI app you already use.

Connect your app.

Every app uses the same server URL. Your app opens Keryx for signup or sign-in and connection approval. Your password and verification code stay on Keryx; there is no API key to copy.

claude mcp add --transport http keryx https://app.keryxmarketing.com/mcp

codex mcp add keryx --url https://app.keryxmarketing.com/mcp

openclaw mcp set keryx '{"url":"https://app.keryxmarketing.com/mcp","transport":"streamable-http","auth":"oauth"}'
openclaw mcp login keryx

{
  "servers": {
    "keryx": {
      "type": "http",
      "url": "https://app.keryxmarketing.com/mcp"
    }
  }
}

Ask for what you need.

Your app chooses the Keryx tools for each request. A few to start with:

• Create an ad for my product at [website or store link]. Choose an approach and show me the finished ad.
• Add my app’s App Store link to Keryx and suggest three ad ideas.
• Turn the second idea into an image ad and a carousel.
• Revise the image: use a shorter headline and show the editing screen.

You stay in control.

You approve each app

Keryx shows which app is asking and what it will be able to do before you connect.

Ad creation uses your credit

Ideas and finished ads use Keryx credit at the same prices as the website. Reading your saved work is free. See pricing

No campaign launches

A connected app can create and revise ads. It can’t launch campaigns or spend ad budget; you launch from Keryx when you’re ready.

Retries don’t charge twice

If a response is lost, repeating the exact request and its request key keeps the same work without charging twice.

Disconnect anytime

In Keryx, open your account menu and choose Connections to see or remove connected apps.

Starting from the website? The agent index links to connection instructions and the first-ad guide.
