Simple MCP Server

Simple MCP Server is an MCP server that serves as a starter template built with TypeScript and the official Model Context Protocol SDK. It connects AI assistants directly to local utility functions and external APIs via standard input and output (stdio) transport. Developers use this template to quickly scaffold and build custom MCP tools and resources without constructing the underlying protocol architecture from scratch. The server comes with pre-built example tools including string echoing, number addition, system time retrieval, and flight status tracking using either mock records or live AviationStack API data. In addition, it exposes static resources such as server metadata and greeting messages. Its modular architecture isolates tool handlers, resource handlers, and registries into distinct classes, allowing engineers to cleanly extend protocol capabilities and link external databases, command-line utilities, or web services into AI agent workflows.

How to install and configure Simple MCP Server

1. Clone the repository and install dependencies by running npm install. 2. Build the project using npm run build. 3. Optionally configure an environment variable such as AVIATIONSTACK_API_KEY for live flight data. 4. Open your MCP client configuration file (such as Claude Desktop or Cursor) and add the server definition under mcpServers using stdio transport: json { "mcpServers": { "simple-server": { "command": "node", "args": ["path/to/dist/index.js"] } } } 5. Replace path/to/dist/index.js with the absolute path to your compiled build output, save the configuration, and restart your MCP client.

What you can do with Simple MCP Server

• Scaffold new Model Context Protocol servers in TypeScript using a pre-configured architecture featuring modular tool and resource registries. * Query real-time international flight details including scheduled departure times, arrival airports, and flight statuses via the AviationStack API. * Inspect local environment variables and system timestamps directly from an AI client interface using built-in utility tools. * Provide static greeting and server capability metadata resources directly to connected LLMs through defined URI resource endpoints. * Test and validate client-to-server JSON-RPC communication over stdio transport during local agent development and debugging sessions.

Part of MCP Servers

How do I install Simple MCP Server?

Clone the repository to your machine, install dependencies using npm install, and compile the TypeScript code with npm run build. Once built, reference the resulting dist/index.js file with node in your MCP client configuration under the mcpServers key.

What can Simple MCP Server do?

It provides built-in tools for echoing text, adding numbers, retrieving the current server date and time, and looking up flight statuses. It also demonstrates how to expose read-only MCP resources for server information and greetings, acting as a modular template for building custom tools.

Which MCP clients work with Simple MCP Server?

Any MCP-compatible client that supports standard input and output transport can connect to this server. This includes AI interfaces such as Claude Desktop and development environments like Cursor when configured with the server node command and path.

How does the flight status tool work?

The flight status tool accepts a flight number and returns departure and arrival details, airline info, and live status. By default, it operates with mock data, but it can fetch live information when provided with an AviationStack API key via the AVIATIONSTACK_API_KEY environment variable.
