Understand the core differences between Machine Client Protocol (MCP) authentication and traditional human authentication, and why agent-first systems need new access models.

Learn the difference between Machine Client Protocol (MCP) and AI agents — and how MCP provides the access and security layer that agents need to function safely.

Explore how Machine Client Protocol (MCP) authenticates agents, validates delegation, and secures machine-to-machine communication.

Learn what an MCP Gateway is, how it fits into the Machine Client Protocol stack, and how it simplifies secure agent access to APIs.

Understand the difference between MCP servers and MCP clients — and how they work together to enable secure access for AI agents and automated systems.

Learn what Machine Client Protocol (MCP) is, why it's suddenly everywhere, and what it means for the future of AI agents, APIs, and secure access.

Understand the difference between Machine Client Protocol (MCP) and Large Language Models (LLMs) — and how they interact in AI-powered systems.

Understand how Machine Client Protocol (MCP) differs from traditional APIs — and why it matters for agent-based access, identity, and control.
