Features

• Exposes Yuno API endpoints as MCP tools
• Enables AI and automation workflows with Yuno
• TypeScript support
• Easy integration with Cursor and other MCP-compatible agents

Using with Cursor or Claude Desktop

You can use this MCP server with Cursor or Claude Desktop to enable AI-driven payment flows, customer creation, and more.

Prerequisites

• For Local MCP Server: Node.js (version 18 or higher) must be installed on your system
• For Remote MCP Server: No additional software required

1. Set Up Your Yuno API Credentials

• Set your Yuno API credentials using environment variables (see config examples below).

2. Add the MCP Server to Cursor

• Open Cursor Settings (Cmd+Shift+P → "Cursor Settings").
• Go to the "MCP" section and click "Add new global MCP server".
• Add the following config (replace the path with your actual build output):

{
    "mcpServers": {
        "yuno-mcp": {
            "type": "command",
            "command": "npx @yuno-payments/yuno-mcp@latest",
            "env": {
                "YUNO_ACCOUNT_CODE": "your_account_code",
                "YUNO_PUBLIC_API_KEY": "your_public_api_key",
                "YUNO_PRIVATE_SECRET_KEY": "your_private_secret_key"
            }
        }
    }
}

3. Add the MCP Server to Claude Desktop

• Open Claude Desktop settings → "Developer" tab → Edit Config.
• Add the following config:

{
    "mcpServers": {
        "yuno-mcp": {
            "command": "npx",
            "args": ["@yuno-payments/yuno-mcp@latest"],
            "env": {
                "YUNO_ACCOUNT_CODE": "your_account_code",
                "YUNO_PUBLIC_API_KEY": "your_public_api_key",
                "YUNO_PRIVATE_SECRET_KEY": "your_private_secret_key"
            }
        }
    }
}

4. Using Remote MCP Server (Alternative)

Instead of running the MCP server locally, you can use the remote MCP server hosted by Yuno. This is useful when you don't want to manage the server locally or for production environments.

For Cursor:

{
    "mcpServers": {
        "yuno-mcp": {
            "type": "http",
            "url": "https://y.uno/yuno-mcp/mcp",
            "headers": {
                "public-api-key": "your_public_api_key",
                "private-secret-key": "your_private_secret_key",
                "account-code": "your_account_code"
            }
        }
    }
}

For Claude Desktop:

{
    "mcpServers": {
        "yuno-mcp": {
            "url": "https://y.uno/yuno-mcp/mcp",
            "headers": {
                "public-api-key": "your_public_api_key",
                "private-secret-key": "your_private_secret_key",
                "account-code": "your_account_code"
            }
        }
    }
}

5. Test the Integration

• In Cursor or Claude, select a Markdown file or chat and ask the agent to create a payment, customer, or checkout session using the yuno-mcp tool.
• Make sure your environment variables are set correctly.

Required environment variables:

• YUNO_ACCOUNT_CODE
• YUNO_PUBLIC_API_KEY
• YUNO_PRIVATE_SECRET_KEY
