MCP Full Course Masterclass 2026: Build and Deploy MCP Server From Scratch - Model Context Protocol

Build one MCP server from scratch and take it all the way to a free public deployment, in 30 lessons. This is the complete MCP Masterclass in one video: four modules, one server called Scribe, and every step shown on my own machine. 🎓 Want to learn Claude Code with me, live? Join the Claude Code Builder cohort on Maven → https://maven.com/genaiunplugged/claude-code-builder By the end you have a Python MCP server that reads and edits a Google Doc, asks you before every write, remembers your rules between chats, posts a draft to Substack, and runs on a web address instead of a pipe, so Claude Desktop on any machine can use it. 🎯 What You'll Learn - Module 1, lessons 1 to 10: what MCP is and why it exists, host, client and server, tools, resources and prompts, and Scribe's first read-only tool inside Claude Desktop - Module 2, lessons 11 to 15: the 5 steps that add any tool, edit_doc as the first write, resources and a prompt - Module 3, lessons 16 to 23: the guard (a fence and a question before every write), 3 attacks and 4 refusals, memory.json with remember and recall, an assignment and its 5-line solution - Module 4, lessons 24 to 30: Substack as a second service, draft to published end to end, Streamable HTTP, a free deployment on Render, the custom connector in Claude Desktop, the three limits of free hosting, the registry pointer 🧰 What You Need - Python 3.12 and a code editor. Claude Desktop and Claude Code (the same server works in both) - A Google Drive folder and a service-account key, built in Module 1 - Lesson pages, the code and a checkpoint zip per module, so you can join at any module: https://www.genaiunplugged.com/courses/mcp/ 🗺️ Where the Map Ends By lesson 30 all 16 boxes on the course map are lit. Scribe has 7 tools, 2 resources, 1 prompt, a guard, a memory and a web address. 📺 CHAPTERS: 0:00 Lesson 1: The demo before the build 3:54 Lesson 2: What MCP actually is 8:36 Lesson 3: The setup that stops the next lessons from breaking 12:56 Lesson 4: 6 steps, 4 traps: connecting your Drive to MCP 19:46 Lesson 5: Why your working script fails one app later 25:17 Lesson 6: Why MCP exists: M times N becomes M plus N 30:35 Lesson 7: Host, client and server in plain English 34:46 Lesson 8: Tools, resources and prompts 38:59 Lesson 9: MCP vs API vs CLI - Difference 46:07 Lesson 10: Module 1 recap 50:40 Lesson 11: Why the official Google Drive server cannot fix one typo 56:23 Lesson 12: Write your first MCP server: one tool that edits a Drive draft 1:03:53 Lesson 13: 6 tests for your MCP server, and the one that fails 1:09:45 Lesson 14: Stop retyping your editing job: resources and prompts 1:15:54 Lesson 15: The hole in the map is gone: module 2 in five points 1:18:43 Lesson 16: The quiet mistake: what a server that can write can do to you 1:23:31 Lesson 17: Build the guard: a fence, and a question before the write 1:32:20 Lesson 18: Try to break your own MCP server: 3 attacks, 4 refusals 1:36:24 Lesson 19: Why every chat starts at zero 1:39:11 Lesson 20: Give your MCP server a memory 1:42:57 Lesson 21: Assignment: a tool that finds a past decision 1:45:15 Lesson 22: Solution: the find_note tool in 5 lines 1:48:08 Lesson 23: Safe to trust: module 3 in five points 1:50:52 Lesson 24: The last manual step: why your finished draft still goes nowhere 1:55:59 Lesson 25: Add your Substack MCP server: a second service in the same 5 steps 2:04:46 Lesson 26: Substack Draft to published, end to end: Scribe sends it, you press Publish 2:09:23 Lesson 27: Off the laptop: the pipe and the web address 2:15:19 Lesson 28: Deploy your MCP server for free, plus the one-minute registry pointer 2:21:53 Lesson 29: Shipped: module 4 in five points 2:24:58 Lesson 30: What you have, what breaks next, and where to go 🔗 RESOURCES Model Context Protocol official site and docs → https://modelcontextprotocol.io Official MCP Python SDK on GitHub → https://github.com/modelcontextprotocol/python-sdk Claude Desktop download → https://claude.ai/download Render docs → https://render.com/docs 📥 Helpful Links: 🌐 Subscribe to GenAI Unplugged Substack → https://genaiunplugged.substack.com/ 🛠️ My AI Systems store → https://store.genaiunplugged.com/ 📚 All my courses → https://genaiunplugged.com/ 🙌 A like is what tells YouTube to show this to the next person looking for the same build.
