OpenAI, Anthropic, and Block Are Teaming Up to Make AI Agents Play Nice

The three companies are also transferring ownership of some widely used agentic technologies over to the foundation. This includes Anthropic’s Model Context Protocol (MCP), which allows agents to connect and interact; OpenAI’s Agents.md, which lets programs and websites specify rules for coding agents; and Goose, a framework for building agents developed by Block. These technologies were already free to use, but through the new foundation it will be possible for others to contribute to their development.

“MCP is used by many companies, but there are others [who don’t use it],” says Nick Cooper, who leads work on the protocol at OpenAI. Cooper says that making MCP an open standard should encourage developers and companies to embrace it and build systems that integrate agentic AI. “That open interoperability—that open standard—really means that companies can talk across providers, and across agentic systems.”
