What is MCP Servers Express?
This is a pre-configured server system that provides various practical functions through the Model Context Protocol (MCP). It is built using the Express.js framework and can easily expand new service endpoints.How to use MCP Servers Express?
After installation, simply run a simple command to start the service, and then access various functions through specific URLs. All services use SSE (Server-Sent Events) technology to achieve real-time communication.Use cases
Suitable for application development that requires quick integration of greeting functions or time services, especially suitable for scenarios that require real-time interaction such as chatbots and customer service systems.Main features
Greeting service
Provides a personalized greeting function that can receive a user name and return a customized greeting message
Time service
Get the current server time in real-time, accurate to the second
SSE technology support
Use Server-Sent Events to achieve real-time one-way communication from the server to the client
Advantages
Ready to use, pre-configured with common services
Based on Express.js, highly scalable
Uses SSE technology to achieve simple and efficient real-time communication
Developed in TypeScript, type-safe
Limitations
Currently, the functions are relatively basic
SSE is one-way communication, not suitable for scenarios that require two-way interaction
Configured for local development environment, additional steps are required for production deployment
How to use
Install dependencies
Use the pnpm package manager to install all dependencies required by the project
