Subtotal Model Context Protocol

The Subtotal Model Context Protocol server allows you to integrate with Subtotal APIs through function calling.

Setup

To run the Subtotal MCP server using npx, use the following command:

# To set up all available tools
npx -y @subtotal-inc/mcp --tools=all --subtotal-secret-key=<SECRET-KEY>

# To set up specific tools
npx -y @subtotal-inc/mcp --tools=get-purchases,get-purchase-details --subtotal-secret-key=<SECRET-KEY>

Make sure to replace <SECRET-KEY> with your actual Subtotal API secret API key value. Alternatively, you could set the SUBTOTAL_SECRET_KEY environment variable.
