The Production Security Gap
When deploying a Remote Multi-Channel Protocol (MCP) server—especially those built on frameworks like FastMCP (inspired by FastAPI)—most tutorials focus solely on functionality: "Use the MCP SDK, set the transport to HTTP, and access your server via http://yourserver:port."
While this is fine for local development or internal testing, it leaves a significant, critical gap for production environments: security.
Exposing an HTTP port directly to the internet is a major security risk. Without a Secure Sockets Layer (SSL/TLS), all data—including potentially sensitive authentication tokens, session data, and application payloads—is transmitted in plain text. For any public-facing or authenticated service, this is completely unacceptable.
The question then becomes: How do we easily secure a remote FastMCP server with SSL?
The simplest MCP server looks like this:
from fastmcp import FastMCP, Context
