Hello World MCP Server

Typescript starter for MCP server with resource, prompt and tool. Exposed over MCP by the hello world mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

A simple Model Context Protocol (MCP) server implementation built with TypeScript. This server demonstrates basic MCP functionality including resources, prompts, and tools.

• SSE and STDIO transport support
• Resource handling with static and dynamic resources
• Sample prompt implementation
• Example tool that echoes messages
• Debug tool for server introspection

Its toolset

Everything the assistant can do here goes through one of these:

• echo — Echoes back a message with "Hello" prefix
• debug — Lists all available tools and methods
• Prerequisites — The Prerequisites tool exposed by this server
• Installation — The Installation tool exposed by this server
• Build — The Build tool exposed by this server
• Resources — The Resources tool exposed by this server
• Tools — The Tools tool exposed by this server
• Prompts — The Prompts tool exposed by this server

Configuration

You will need one environment variable: YOUR_SESSION_ID. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

• Node.js (v16 or higher) - npm or yarn

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Hello World's toolset — echo, debug, Prerequisites and 5 more — is a fair guide to whether it matches your workflow. It is maintained by madhukarkumar; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the hello world mcp server does with a few real requests.
