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 LLMs and AI agents with 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

Features

The MCP server has near parity with the Paddle API, allowing AI assistants and agents to:

• Manage your full Paddle catalog
• View customer, purchase, and provisioning information
• Handle subscription, payment, and refund workflows
• Debug billing and order management issues
• Create and adjust transactions directly in conversation
• Generate financial reports for financial and operational insights
• Implement and test Paddle integrations faster

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)", "--tools=(all|read-only|non-destructive|tool_name1,tool_name2,...)"]
    }
  }
}

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

You can also filter the tools available to the MCP server by passing the --tools argument. Accepted values are all, read-only, non-destructive, or a comma-separated list of tool names. The default is non-destructive.

For detailed setup guides, see:

• Claude Desktop
• Cursor
• Windsurf

Development

1. Install dependencies:

   pnpm install

2. Build the server:

   pnpm build

3. Update client to use the local build:

   {
     "mcpServers": {
       "paddle": {
         "command": "node",
         "args": ["path/to/paddle-mcp-server/build/index.js"],
         "env": {
           "PADDLE_API_KEY": "your_api_key",
           "PADDLE_ENVIRONMENT": "sandbox",
           "PADDLE_MCP_TOOLS": "all"
         }
       }
     }
   }

   The PADDLE_MCP_TOOLS environment variable accepts the same values as the --tools argument: all, read-only, non-destructive, or a comma-separated list of tool names. If not set, defaults to non-destructive.

Debugging

To debug the MCP server, you can use the MCP Inspector tool:

1. Run the server with the inspector:

   pnpm inspector

2. Open the provided URL in your browser to view and debug the MCP requests and responses.

3. Include the --api-key and --environment arguments.
