MCP security: Implementing robust authentication and authorization

The Model Context Protocol (MCP) is increasingly relevant in today’s agentic AI ecosystem because it standardizes how AI agents access tools, data sources, and external systems. As agents move from passive chatbots to autonomous actors capable of planning and executing tasks, MCP provides a structured, interoperable interface layer that enables tool invocation with enhanced security, controlled access to external systems, and more consistent policy enforcement across heterogeneous environments.. In essence, MCP forms the connective tissue between LLM-driven reasoning and real-world system ex
