  "mcpServers": {
    "zhangzhongnan928-mcp-coinbase-commerce": {
      "command": "node",
      "args": [
        "/path/to/mcp-coinbase-commerce/dist/index.js"

You run a dedicated MCP server that connects to Coinbase Commerce to generate cryptocurrency payment links. It lets you create customizable payment charges and look up existing charges, all managed through secure API access and MCP-compatible clients.

How to use

You connect this MCP server to your MCP-enabled assistant or client to generate Coinbase Commerce payment links. Provide the desired amount, currency, and a description, and the server returns a payment link you can share with customers. You can also query the status or details of existing charges using the available tools.

Configuration for MCP clients

To connect a client (for example, Claude or another MCP-compatible helper) to this server, run the server locally and expose it to your MCP client as shown below. The client should invoke the MCP server using the provided command and environment configuration.

{
  "mcpServers": {
    "coinbase-commerce": {
      "command": "node",
      "args": ["/path/to/mcp-coinbase-commerce/dist/index.js"],
      "env": {
        "COINBASE_COMMERCE_API_KEY": "your_api_key_here"
      }
    }
  }
}

Security and keys

Keep your Coinbase Commerce API key secure. Do not expose it in client-side code or share it in logs. Use a secure environment and rotate keys if you suspect exposure.

API Tools

The server provides two core tools to manage Coinbase Commerce charges.

Creating a charge

Tool: create-charge. Use this to generate a new payment link with a name, description, amount, currency, and optional redirect URL after payment.

Getting charge information

Tool: get-charge. Retrieve details about an existing charge using its chargeId.

Development

For development, run the server in development mode to enable hot-reload and faster testing.

# Development mode
npm run dev

Testing and inspection
