AI infrastructure is evolving rapidly. MCP (Model Context Protocol) standardizes how agents access tools and data. Workload identity (SPIFFE) gives agents cryptographic credentials. OPA policies control what agents can access. This module connects RAG engineering with infrastructure security.
MCP: Model Context Protocol
MCP provides a standard protocol for AI agents to access external tools, data sources, and resources. Instead of building custom integrations for each tool, agents speak MCP to any MCP-compatible server.
AI Agent Identity
In production, AI agents need identity just like microservices. Who is this agent? What is it allowed to access? SPIFFE provides cryptographic identity for agents. OPA policies control access per agent role.
Building Future-Proof AI Infrastructure
- Separation of concerns: Retrieval, generation, and tool execution as separate services
- Identity-first: Every agent and service has cryptographic identity
- Observable: Every request traced, every token counted, every access audited
- Secure by default: mTLS between services, OPA at decision points
