What is the MCP server?

The MCP server is an example service based on the Model Context Protocol. Its main function is to perform basic calculator operations. It supports two connection methods: SSE (Server-Sent Events) for real-time communication and stdio for local debugging.

How to use the MCP server?

You can start the server by directly running the Python script or use the MCP development tool for a better development experience. The client can choose either the SSE or stdio method to connect to the server.

Applicable scenarios

It is suitable for development scenarios that require quick verification of the MCP protocol, teaching examples for learning the working principle of the MCP protocol, and prototype development that requires simple calculation services.

Main features

Basic calculation functionSupports basic mathematical operations such as addition, subtraction, multiplication, and division
Dual transmission modesSupports both SSE (real-time event stream) and stdio (standard input/output) communication methods
Integration with development toolsIntegrated with MCP Inspector, providing hot reloading and debugging functions

Advantages and limitations

Advantages
Simple and easy to use, quick to get started
Provides two communication methods to adapt to different scenarios
The development tool supports hot reloading, improving development efficiency
Limitations
The functions are relatively basic, only supporting calculator operations
Additional configuration is required for the production environment
Documentation and community support are relatively limited

How to use

Install dependencies
First, you need to install all necessary Python dependency packages
Start the server
You can choose to run directly or use the development tool to run
Connect the client
Choose the SSE or stdio client to connect according to your needs

Usage examples

Development and debuggingUse the stdio client for local debugging during the development process
Real-time calculation serviceUse the SSE client to connect to the remote server to obtain real-time calculation results

Frequently Asked Questions
