What is MCP Server?

MCP Server is the implementation end of the Model Context Protocol, responsible for connecting your custom services (such as weather queries) with AI models (such as Claude). It serves as an intermediate bridge to handle communication between AI models and specific business logic.

How to use MCP Server?

By configuring a JSON file to specify the service startup command, clients such as Claude can automatically discover and call your services. Services need to implement specific interface specifications.

Applicable scenarios

Suitable for scenarios where AI capabilities need to be integrated with business systems, such as: - Real-time data query (weather/stocks) - Calls to enterprise internal systems - Customized AI function expansion

Main features

Service integration
Package any Java service into a tool that can be called by AI
Protocol standardization
Unify the communication protocol to support calls from multiple clients
Lightweight deployment
Provide services through a simple JAR package
Advantages
Quickly AI-ize existing services
Support the decoupling of business logic and AI models
Simple configuration and low development threshold
Limitations
Currently only supports JDK17 and below
Need to follow specific interface specifications
Performance depends on the implementation of local services

How to use

Prepare service implementation
Develop and implement a Java service for business logic and package it into an executable JAR
Configure the client
Add service configuration in claude_desktop_config.json
Start the service
Restart the client to automatically connect to the service

Usage examples

Weather query service
Get real-time weather information by city name
Data query service
Connect to the enterprise internal database to provide business data
