How to Authenticate Your MCP Server (And Finally Control Who Pays for Access) + n8n community node

Tired of struggling with MCP Server Authentication while building remote AI tools, Python projects, or connecting n8n workflows? You’re not alone—a lot of us want to secure our MCP servers (especially FastAPI MCP Server setups) but run into roadblocks with authentication, API keys, or Bearer tokens. *Chapters* 0:00 Intro 0:18 Overview 01:12 Python MCP Server + FastAPI wrapper 04:00 Adding Authentication 05:20 Mock User Database 05:57 Run server locally 06:40 Test with MCP Inspector 08:17 Host on Render.com 09:03 Connect with n8n 11:17 Bonus: Fix n8n community bug 13:19 Outro In this video, I break down exactly how to build an authenticated API with your FastAPI MCP Server, plus tips on using authentication middleware, API Key Authentication, and Bearer Token Authentication. You’ll see how this unlocks real control—set up proper access, connect your N8n MCP client, and even start to monetize your MCP Server instead of leaving it open to freeloaders. This isn’t just a generic MCP Authentication Tutorial—it’s a straight walk-through to making your MCP API secure, whether you’re deploying on Render, using Python FastAPI Docker, or fixing n8n-MCP bugs. If you’re ready to move beyond the basics and actually put a lock on your cloud-hosted MCP Server, hit play and let’s get you set up the right way.
