In this MCP tutorial, we build a custom server from scratch with FastMCP and connect it to an external API. You’ll learn how the Model Context Protocol works, how MCP servers expose tools to AI agents, and how to define tools with the Python SDK. We start with a minimal MCP server and then build a practical web-data tool that an AI agent can actually use. Along the way, we cover the three main MCP types (tools, resources, and prompts) and explain why each part matters. The tutorial also walks through connecting the server to Claude Desktop, testing it, and troubleshooting some of the common issues you may encounter when building an MCP server. If you're looking to build an MCP server from scratch, this guide is your quick starting point to creating custom tools for Claude and any other AI agents. 📚 *MENTIONED RESOURCES* ✏️ Node.js download: https://nodejs.org/en/download ✏️ Claude Code docs: https://code.claude.com/docs/en/ ✏️ Oxylabs MCP Server on GitHub: https://oxy.yt/7EJV ✏️ Oxylabs Agent Skills on GitHub: https://oxy.yt/pEKa ✏️ MCP docs: https://modelcontextprotocol.io/docs/develop/build-server 🎥 *RELATED VIDEOS* 👉 What Is an MCP Server: https://oxy.yt/NELd 👉 Vibe Coding with Claude Code: https://oxy.yt/UEZ7 🔧 *OUR SCRAPING SOLUTIONS* Web Scraper API: 👉 https://oxy.yt/5EDc Residential Proxies: 👉 https://oxy.yt/CEFp ISP Proxies: 👉 https://oxy.yt/zEGo Datacenter Proxies: 👉 https://oxy.yt/tEHO ⏱️ *TIMESTAMPS* 00:00 – Intro 00:38 – What is an MCP server? 01:35 – Prerequisites 02:04 – Build an MCP server 03:16 – Code review 04:58 – MCP inspector test 06:05 – Claude Code demo 07:08 – Connect MCP to Claude Desktop 08:52 – Common pitfall 09:16 – Local vs Hosted MCP 10:02 – Alternatives for scraping 11:35 – Next steps 💬 *CONNECT WITH US* Website: https://oxylabs.io LinkedIn: https://www.linkedin.com/company/oxylabs-io X: https://x.com/Oxylabs_io Support: [email protected] #MCP #AIagents #ModelContextProtocol
