Security in MCP is complicated. Not because the framework is overly complex, but because security in AI systems involves challenges that traditional web applications don't face.
Think about it: when an AI agent uses MCP to access resources and execute tools, it's not just making API calls; it's potentially accessing sensitive data, performing actions with real-world consequences, and making decisions that affect users and systems. The security implications are significant.

Figure 5.4 – MCP security approaches
MCP approaches security through multiple layers, which I think is the right approach. At a minimum, implementations should secure the transport layer (e.g., TLS for encrypted HTTP) and implement robust authentication, authorization, and audit logging. Authentication and authorization are deliberately left up to implementers: for HTTP-based transports, the official authorization specification builds on...
