MCPOpen SourceMIT14.8

by nusashi • Testing & QA

A tiny TypeScript implementation of a Model Context Protocol (MCP) server that responds with "Hello MCP World!" — ideal for learning and local testing.

Example Use Cases

1
A minimal, local MCP endpoint to test tools/list and tools/call interactions.
2
A simple TypeScript reference implementation to learn how to implement MCP servers and transports (stdio).
3
An example to integrate an MCP server with desktop clients like Claude Desktop or cline for local tool invocation.

Description

This repository provides an ultra-minimal MCP server written in TypeScript (44 lines) that exposes a single tool which returns "Hello MCP World!". It demonstrates basic MCP capabilities (tools and resources) and how to run the server over stdio, with example integration notes for Claude Desktop and cline. It's intended as a learning and prototyping starting point for implementing MCP locally and understanding tool calls and listing.
