Model Context Protocol (MCP).

Learn what Model Context Protocol (MCP) means in modern AI and large language models.

Part of speechnoun

An open standard introduced by Anthropic in 2024 for connecting AI assistants to data sources, tools, and applications through a uniform interface.

MCP standardizes the wiring between AI models and the outside world. Instead of every AI app inventing its own tool-calling format, MCP defines a common protocol any model can use to discover and invoke tools. By 2026 it's been adopted by Anthropic's Claude, OpenAI, Google, and most major agent platforms.

For marketers, MCP matters because it's what makes AI agents practical at scale. An agent that can speak MCP can plug into your CRM, analytics, CMS, and ad platforms without custom integration work.
