# MCP Server for Paddle Billing

[Paddle Billing](https://www.paddle.com/billing?utm_source=dx&utm_medium=paddle-mcp-server) 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)](https://modelcontextprotocol.io/introduction) 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](https://developer.paddle.com/classic/api-reference/1384a288aca7a-api-reference?utm_source=dx&utm_medium=paddle-mcp-server)

## 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>

Adding the following to your MCP settings file will configure and run the Paddle MCP server in a client like Claude Desktop, Cursor or Windsurf:

### Method 1: One-click installation in Cursor or VS Code

You can install the Paddle MCP server with a single click in Cursor or VS Code.

[![Install in Cursor](https://cursor.com/deeplink/mcp-install-dark.svg)](https://cursor.com/en-US/install-mcp?name=paddle&config=eyJlbnYiOnsiUEFERExFX0FQSV9LRVkiOiJ5b3VyX2FwaV9rZXkiLCJQQURETEVfRU5WSVJPTk1FTlQiOiJzYW5kYm94IiwiUEFERExFX01DUF9UT09MUyI6Im5vbi1kZXN0cnVjdGl2ZSJ9LCJjb21tYW5kIjoibnB4IC15IEBwYWRkbGUvcGFkZGxlLW1jcCJ9)

<a href="vscode:mcp/install?%7B%22name%22%3A%22paddle%22%2C%22type%22%3A%22stdio%22%2C%22command%22%3A%22npx%22%2C%22args%22%3A%5B%22-y%22%2C%22%40paddle%2Fpaddle-mcp%22%5D%2C%22env%22%3A%7B%22PADDLE_API_KEY%22%3A%22your-api-key%22%2C%22PADDLE_ENVIRONMENT%22%3A%22sandbox%22%2C%22PADDLE_MCP_TOOLS%22%3A%22non-destructive%22%7D%7D">
  <img src="https://img.shields.io/badge/VS_Code-Add_Paddle_MCP-0098FF?style=flat-square&logo=visualstudiocode&logoColor=ffffff">
</a>

After installation, you'll need to update the configuration in your MCP settings file to replace `your_api_key` with your actual Paddle API key and adjust the environment and tools values as needed.

### Method 2: Using command-line arguments (Recommended for `npx`)

Add the following to the MCP settings or configuration file in the client you're using:

```json
{
  "mcpServers": {
    "paddle": {
      "command": "npx",
      "args": [
        "-y",
        "@paddle/paddle-mcp",
        "--api-key=your_api_key",
        "--environment=sandbox",
        "--tools=non-destructive"
      ]
    }
  }
}
```

Replace `your_api_key` with your actual Paddle API key, set `--environment` to either `sandbox` or `production`, and set `--tools` to the tools which you want to be loaded and available to the MCP client.

### Method 3: Using environment variables

Add the following to the MCP settings or configuration file in the client you're using:

```json
{
  "mcpServers": {
    "paddle": {
      "command": "npx",
      "args": ["-y", "@paddle/paddle-mcp"],
      "env": {
        "PADDLE_API_KEY": "your_api_key",
        "PADDLE_ENVIRONMENT": "sandbox",
        "PADDLE_MCP_TOOLS": "non-destructive"
      }
    }
  }
}
```

Replace `your_api_key` with your actual Paddle API key, set `PADDLE_ENVIRONMENT` to either `sandbox` or `production`, and set `PADDLE_MCP_TOOLS` to the tools which you want to be loaded and available to the MCP client.

### Filtering tools

You can filter which [tools](#available-tools) are loaded and available to the MCP client by passing the `--tools` argument (Method 2) or setting the `PADDLE_MCP_TOOLS` environment variable (Method 1 or 3). Accepted values are:

* `all` - All tools are available
* `read-only` - Only read operations are available
* `non-destructive` - Read operations and safe write operations are available (default)
* A comma-separated list of specific tool names (e.g., `list_products,get_product,create_product`)

For detailed setup guides, see:

* [Claude Desktop](https://modelcontextprotocol.io/quickstart/user)
* [Cursor](https://docs.cursor.com/context/model-context-protocol)
* [Windsurf](https://docs.codeium.com/windsurf/mcp)

## Development

1. Install dependencies:

   ```bash
   pnpm install
   ```

2. Build the server:

   ```bash
   pnpm build
   ```

3. Update client to use the local build:

   ```json
   {
     "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:

   ```bash
   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.
