## Executive Summary
Learn how to secure multi-agent AI systems with cryptographic identity using Keyfactor EJBCA and AWS services.

## Why It Matters (Strategic Analysis)
The Model Context Protocol's lack of built-in authentication creates severe vulnerability vectors in enterprise multi-agent workflows accessing production tool servers. Integrating X.509 PKI with real-time OCSP validation establishes identity-bound execution, enforcing explicit delegation and cryptographic proof-of-possession across transport-agnostic LLM tool calls.
