This is a minimal Model Context Protocol (MCP) server implemented in TypeScript, primarily intended to serve as a Test Double / Mock Server.

The MCP Hello World server is a lightweight, controllable, and predictable environment designed for unit and integration testing of client code that interacts with an MCP server. It is not intended for production use but provides a reliable test double for developers to isolate client logic from real server dependencies. The server supports both STDIO and HTTP/SSE transport protocols, making it versatile for different testing scenarios. It offers simple, fixed behaviors through its echo and debug tools, ensuring predictability and ease of use in test assertions. With fast startup and response times, it is well-suited for frequent use in automated test environments.

Features

  • Isolation: Focus tests on client logic without real server dependencies.
  • Predictability: Simple, fixed behaviors for easy test assertions.
  • Speed: Fast startup and response times for frequent testing.
  • Lightweight: Minimal dependencies for easy integration.
  • Protocol Coverage: Supports STDIO and HTTP/SSE MCP transport protocols.
