MCP SERVER TEMPLATE

What is MCP-SERVER-TEMPLATE?

MCP-SERVER-TEMPLATE is a TypeScript-based starter template for building Model Context Protocol (MCP) servers using the official MCP SDK. It acts as an interface between user queries and tool execution, enabling AI assistants and external systems to dynamically call tools, interpret prompts, and manage resources in a modular and extensible way.

How to use MCP-SERVER-TEMPLATE?

Clone the repository, run npm install, configure environment variables (e.g., TRANSPORT_TYPE, HTTP_PORT) in a .env file, then start the server with npm start (production) or npm run dev (development). Use npm run test:http to test the HTTP transport, npm run mcp:inspector to launch the MCP Inspector GUI for debugging.

Key features of MCP-SERVER-TEMPLATE

• Modular architecture with separation of concerns
• Transport abstraction for HTTP (stateless) and stdio (stateful)
• Dependency injection for testability and decoupling
• Tool system with Zod schema validation and auto-generated JSON schema
• Extensible prompt and resource scaffolding for LLM workflows
• Built-in testing with Jest and MCP Inspector GUI

Use cases of MCP-SERVER-TEMPLATE

• Building conversational MCP servers for AI assistants
• Creating a backend to manage callable tools for LLM-based workflows
• Prototyping LLM toolchains or integrating with proprietary systems
• Preparing a scalable production MCP assistant backend
