Completed the course Model Context Protocol: Advanced Topics, covering production-level MCP server patterns and communication mechanisms.

Course takeaways:

• Implementing sampling so MCP servers can request AI model calls through clients
• Building real-time progress and logging notification systems for long-running operations
• Roots-based file access control for secure directory permission management
• Stdio vs. StreamableHTTP transport mechanisms and when to use each
• Production scaling strategies - stateless HTTP for horizontal scaling with load balancers
