Overview
What is MCP SERVERS EXPRESS?
MCP SERVERS EXPRESS is a template project that shows how to host multiple Model Context Protocol (MCP) endpoints using an Express.js backend. It is intended for developers who want a starting point to build and run MCP servers with SSE transport.
How to use MCP SERVERS EXPRESS?
Install dependencies with pnpm install, then run the development server with pnpm run dev for hot‑reloading. For production, first build the TypeScript code, then start the server. It listens on http://127.0.0.1:3000 by default. Two built‑in MCP endpoints are available: /greet/sse (provides a greet tool) and /time/sse (provides a get‑time tool).
Key features of MCP SERVERS EXPRESS
- Hosts multiple MCP endpoints on a single Express.js server
- Uses Server‑Sent Events (SSE) for MCP communication
- Includes a greet tool and a get‑time tool out‑of‑the‑box
- Supports hot‑reloading during development
- Written in TypeScript for type safety
Use cases of MCP SERVERS EXPRESS
- Quickly prototyping and testing multiple MCP tools locally
- Demonstrating how to combine MCP with an Express.js backend
- Serving as a base template to add custom MCP endpoints
- Learning how SSE‑based MCP servers are structured
