概要
What is MCP Server Template?
A lightweight and extensible Model Context Protocol (MCP) server implementation built with Express.js and TypeScript. It provides a foundation for building AI-powered applications that communicate with MCP-compatible clients through Server-Sent Events (SSE). The template includes a note management system and is intended for developers starting a new MCP server project.
How to use MCP Server Template?
Clone the repository, run npm install, then npm run build and npm start. The server starts on port 3123 by default. Alternatively, build a Docker image with docker build -t mcp-template . and run docker run -p 3123:3123 mcp-template. To test the SSE endpoint, connect to GET /mcp/sse.
Key features of MCP Server Template
- Express.js server with TypeScript support
- Server-Sent Events (SSE) for real-time communication
- Full MCP protocol implementation
- Built-in note management system (CRUD operations)
- Docker support for containerized deployment
- Input validation using Zod
Use cases of MCP Server Template
- Building a custom MCP-compatible AI assistant with note‑taking capabilities
- Prototyping an MCP server that manages structured data (e.g., notes)
- Creating a real‑time MCP endpoint with SSE for client‑server communication
- Using as a starting point for any MCP server project that requires Express.js and TypeScript
よくある質問
What are the dependencies and runtime requirements?
Node.js 22 or higher and npm are required. Docker is optional for containerized deployment.
Which tools does the server expose?
The server provides five tools: `add-note`, `update-note`, `get-note`, `get-all-notes`, and `delete-note`. Each accepts parameters such as `noteTitle`, `noteContent`, and `noteTags` (optional) as specified in the README.
How does input validation work?
All incoming requests are validated at runtime using Zod schemas before processing, ensuring type safety and data integrity.
How can I configure the server?
Environment variables include PORT (default 3123), LOG_LEVEL (default "info"), DOCKER (set to "true" when running in Docker), and DEV (set to "true" for development mode).
