Model Context Protocol (MCP): Standardizing Interoperability for Agentic AI Systems

The Model Context Protocol (MCP) is an open, vendor-neutral interoperability standard designed to standardize connections between large language models (LLMs) and external data sources, tools, and runtime environments for agentic AI systems. It eliminates the need for custom, one-off integrations between individual LLMs and third-party services, reducing engineering overhead for enterprise agent deployments. MCP operates as a universal translation layer, allowing agent harnesses to access external context, execute tool calls, and interact with runtime environments without bespoke configuration for each model or service pairing. MCP emerged in response to a fragmented landscape of LLM gateway and orchestration tools, which often required significant custom engineering to align with enterprise data governance requirements and existing workflow infrastructure. By providing a shared, open specification for context and tool integration, MCP reduces vendor lock-in for organizations building scalable agentic workflows, and aligns with broader industry efforts to standardize agent interoperability. It sits alongside other orchestration tools, but focuses specifically on context and tool connectivity rather than full workflow routing or model management.
