The Model Context Protocol is open-sourced
Anthropic · · Protocol
Anthropic published MCP, an open standard and reference servers for connecting assistants to data sources and tools through one protocol instead of bespoke integrations.
Why it matters
The integration layer the agent era had been missing. Within a year it was adopted across competing labs and tools, making it the rare piece of AI infrastructure that became a shared standard rather than a moat.
This is LLM World's historical reading, not a claim by Anthropic. The facts above and the sources below are what it rests on.

Anthropic's own announcement, dated Nov 25, 2024 on the page. Typed product_launch for lack of a better value in the schema — MCP is a protocol and reference implementation, not a product; 'architecture' was the alternative and reads as model architecture in this dataset. No archived capture recorded; one should be added.
