The Model Context Protocol (MCP) lets AI agents call external tools and data sources. Created by Anthropic in November 2024, now an open standard with 97M+ monthly SDK installs and growing infrastructure across multiple registries.
MCP standardizes how AI agents discover and call external capabilities — file systems, databases, APIs, custom tools. It's the "USB-C for agents": one protocol, many providers. Both Anthropic Claude and an expanding set of agent frameworks (LangChain, AutoGPT, custom builds) consume MCP servers.
