MCP Ping-Pong Server

Example Use Cases

• 1

  Test and validate MCP command handling (e.g., ping, pong, count) over a simple HTTP API.

• 2

  An example of streaming MCP interactions using Server-Sent Events (SSE) to receive incremental or real-time responses.

• 3

  A thread-safe, minimal server example to experiment with session management and concurrent MCP calls.

Description

This repository implements a simple, educational Ping-Pong MCP server using FastAPI and a FastMCP backend to expose MCP commands over REST and SSE transports. It includes examples for both API-based and SSE-based clients, a small UI, and thread-safe session management for concurrent use. The project is useful for learning how to integrate MCP command handling, testing agent interactions, and experimenting with streaming responses via SSE.
