Security is the backbone of MCP adoption. This guide covers the full security stack—from OAuth 2.1 authentication and fine-grained scopes to securing inter-agent communication protocols like Agent2Agent and Agent Connect.
Deploying Model Context Protocol servers successfully requires architecting for microservice-grade resilience, security, and scalability. From selecting the right transport to instrumenting observability and ensuring OAuth 2.1 compliance, MCP runtime design turns an open protocol into a production-ready foundation for connected AI agents and enterprise automation.
