Payments Developer Portal MCP Server

A Model Context Protocol (MCP) server implementation that connects to a payments company’s developer portal hosted on Firebase. This server provides AI assistants with access to payment documentation, APIs, and guides through the MCP TypeScript SDK.

What is MCP?

The Model Context Protocol (MCP) lets you build servers that expose data and functionality to LLM applications in a secure, standardized way. Think of it like a web API, but specifically designed for LLM interactions.

MCP servers can:

• Expose data through Resources
• Provide functionality through Tools
• Define interaction patterns through Prompts
