MCP Server Quick Start

The MCP server enables you to integrate the Visa Acceptance APIs using tool calling. This process supports multiple tools that can access the Visa Acceptance Platform APIs, such as Pay by Link and Invoicing. This is a local MCP server.

Follow these steps to create a MCP server using npx with your merchant credentials and preferred tools.

Run one of these commands to access the Visa Acceptance MCP server. These commands use the test environment.

Enable all tools:: npx -y @visaacceptance/mcp --tools=all --merchant-id=MERCHANT_ID --api-key-id=API_KEY_ID --secret-key=SECRET_KEY
Enable specific tools:: npx -y @visaacceptance/mcp --tools=tool.values --merchant-id=YOUR_MERCHANT_ID --api-key-id=YOUR_API_KEY_ID --secret-key=YOUR_SECRET_KEY

To enable specific tools, choose the tools you want to utilize and concatenate their values in the

tools

parameter using the comma character (
