MCP Security Fundamentals Course

This MCP security course by Dan Barona (AI Security University) covers how AI agents connect to external systems and how to secure them using the OWASP MCP Top 10 and the "lethal trifecta" framework 0:22.
Key Takeaways:
• MCP lets anyone attach "skills" to AI models (GitHub, Slack, Stripe), with 10,000+ public servers since Anthropic's 2024 launch—and anyone can create an MCP for any service 8:58
• The Postmark incident showed one BCC line in a community-built MCP silently copied every user email—use vendor-built MCPs first 2:20
• The "lethal trifecta" (private data + untrusted content + external comms) makes agents unconditionally vulnerable; remove one leg to break the attack 23:11
• OWASP MCP Top 10 covers token mismanagement, scope creep, tool poisoning, supply chain, injection, intent subversion, auth, audit logging, shadow servers, oversharing—each with real incidents and fixes like vaulting secrets, JIT tokens, signed schemas, and tenant isolation tests 30:52
• The course closes with a six-pillar security bar, ten "Monday morning" actions, and frameworks (EU AI Act, NIST AI RMF, ISO 42001) 2:01
Core lesson: break the trifecta—remove one leg and the attack class cannot complete 2:01.
