- Uses the official MCP Python SDK.
- Provides a calculator tool (add) and a dynamic greeting resource.
- Employs FastMCP for server initialization and tool/resource decorators.
- Demonstrates testing with the MCP Inspector via mcp dev.
- Shows client integration with Claude Desktop via mcp install.
- Covers deployment topics: security, scalability, and monitoring.
The guide is used by following its sections: install the SDK with uv add "mcp[cli]" or pip install mcp, write a server using FastMCP, test with mcp dev server.py, and deploy with security and scalability considerations.
Quickstart Guide to Building an MCP Server in Python
Introduction
The Model Context Protocol (MCP) by Anthropic enables AI agents to interact with external tools, data sources, and services. This guide walks you through building an MCP server in Python using the official MCP Python SDK, integrating it with AI assistants, and deploying it for production use.1. Overview of the MCP Python SDK
The MCP Python SDK provides tools to build MCP servers and clients, facilitating seamless integration between Large Language Models (LLMs) and external data sources or tools. This SDK adheres to the full MCP specification, ensuring compatibility and standardization. (GitHub Repository)
2. Installation
To integrate MCP into your Python project, it's recommended to use uv, a Python package manager:
uv add "mcp[cli]"
Alternatively, if you're using pip:
pip install mcp
3. Quickstart: Building an MCP Server
Let's create a simple MCP server that offers a calculator tool and a personalized greeting resource:
```python
from mcp.server.fastmcp import FastMCP
