MCP Mastery: Build, Secure, and Ship Model Context Protocol Servers track
Module 05 of 8~16 minPro

Securing MCP Servers: Permissions, Least-Privilege, and Sandboxing

The spine of the course. The confused-deputy and prompt-injection threat model, permission-approval workflows, least-privilege tool scoping, sandboxing shell and file access, auth, and the OpenClaw and DOCKER-USER hardening lessons. What you should never give a server access to.


§  You will learn
  • Articulate the MCP threat model: why a server is both a confused deputy and a prompt-injection surface, and what that means for tool design.
  • Apply least-privilege scoping to tools, file access, and shell access so a compromised prompt cannot do maximum damage.
  • Secure remote MCP servers with bearer-token auth, a reverse proxy, allowlists, and host-level firewall rules that catch Docker-exposed ports.
  • Design permission-approval workflows that survive restarts and stay usable for always-on agents.
