Quickstart

Get up and running in 2 minutes.

1. Get your API key

You received your API key when you signed up. It starts with kstk_.

If you lost it, contact eddie@klickstark.de.

2. Add the MCP server

Add this to your MCP configuration:

{
  "mcpServers": {
    "ab-test-library": {
      "url": "https://mcp-server-production-c654.up.railway.app/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Replace YOUR_API_KEY with your kstk_... key.

Where does this go?

The config file location depends on your client. See the Setup Guides for exact paths.

3. Restart your AI tool

Restart Claude Desktop, Cursor, or whichever MCP client you use. You should see 7 tools available.

4. Try it

Ask your AI assistant:

• "Search for hero headline A/B tests"
• "What works in trust sections?"
• "Build me a wireframe brief for a SaaS landing page"
• "Show me pricing page patterns backed by data"
• "What psychological principles drive CTA conversions?"

The assistant will automatically call the appropriate tools and return data-backed recommendations.
