MCP Server for Paddle Billing

Paddle Billing is the developer-first merchant of record. We take care of payments, tax, subscriptions, and metrics with one unified API that does it all.

This is a Model Context Protocol (MCP) server that provides tools for interacting with the Paddle API.

Important: This MCP server works with Paddle Billing. It does not support Paddle Classic. To work with Paddle Classic, see: Paddle Classic API reference

Installation

To use the MCP server, you'll need an API key. You can create and manage API keys in Paddle > Developer tools > Authentication:

• Sandbox: https://sandbox-vendors.paddle.com/authentication-v2
• Live: https://vendors.paddle.com/authentication-v2

To run the server in a client like Claude Desktop, Cursor or Windsurf, add the following to your MCP config:

{
  "mcpServers": {
    "paddle": {
      "command": "npx",
      "args": ["-y", "@paddle/paddle-mcp", "--api-key=PADDLE_API_KEY", "--environment=(sandbox|production)"]
    }
  }
}

Replace PADDLE_API_KEY with your API key, and pass the correct value as environment.

For detailed setup guides, see:

• Claude Desktop
• Cursor
• Windsurf
