Zettle MCP by usefulapi

Use your Zettle account from Claude, Cursor, or any MCP client. Read sales, refunds, products, stock, balance and payouts, and create products. Hosted, no local install: connect with your own credentials.

Live endpoint: https://zettle.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://zettle.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http zettle https://zettle.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "zettle": {
      "url": "https://zettle.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and you sign in with your Zettle account.

On first connect you sign in to Zettle and approve access. Only the Zettle account owner can approve it. You can disconnect it any time in Zettle. No keys go in config files.
