概览

What is Introduction to MCP?

A minimal MCP (Model Context Protocol) server and client example that demonstrates basic calculator operations. It supports both SSE and stdio transports and is intended for developers learning how to build and test MCP servers and clients.

How to use Introduction to MCP?

Install dependencies with pip install -r requirements.txt and the MCP CLI with pip install mcp[cli]. Run the server using mcp dev server.py (starts the MCP Inspector proxy on port 6277) or python server.py (runs the FastMCP server directly on port 8050). Then launch a client script: python client_stdio.py for stdio transport or python client_sse.py for SSE transport.

Key features of Introduction to MCP

Provides a minimal calculator example (add, subtract, multiply, divide)
Supports both stdio and SSE transports
Includes a ready-to-run client for each transport
Uses FastMCP for server implementation
Offers a development mode with hot-reloading via mcp dev

Use cases of Introduction to MCP

Learning how to set up and run an MCP server and client
Testing basic calculator operations with different transport protocols
Debugging MCP interactions using the Inspector proxy in development mode
Understanding the difference between mcp dev and direct Python execution

常见问题

What transports are supported?

The server supports stdio (client launched as subprocess) and SSE (client connects via HTTP event stream).

How do I run the server on port 8050 as defined in server.py?

Execute `python server.py` directly. The `mcp dev` command runs the MCP Inspector on port 6277, not on the port defined in server.py.

What is the difference between `mcp dev server.py` and `python server.py`?

`mcp dev server.py` starts the MCP Inspector with a proxy server on port 6277 for development and debugging. `python server.py` runs your FastMCP server directly on the port specified in the code (8050).

What dependencies are required?

The project lists dependencies in `requirements.txt` and requires the `mcp` package (install with `pip install mcp[cli]`).
