Anthropic introduced the Model Context Protocol (MCP) with Claude 4 in May 2025 as an open connector framework for linking Claude to external tools, services, and data sources.

Summary

In May 2025, Anthropic shipped an open, standardized protocol alongside Claude 4 that serves as the universal adapter layer for plugging the model into outside tools, APIs, and data sources. This matters because it means the system can rely on MCP as the canonical, non-proprietary way Claude talks to the outside world, rather than assuming a tangle of one-off, vendor-specific integrations.
