   • 2025 December 10, Hayden Field, “AI companies want a new internet — and they think they’ve found the key. MCP has already taken the industry by storm, and now Anthropic is giving it away”, in The Verge‎:

     MCP, or Model Context Protocol, began as a passion project from two Anthropic employees, but since its creation in mid-2024, it’s been widely adopted by companies like OpenAI, Google, Microsoft, and Cursor. There are even hints that Apple will use MCP in its forthcoming AI-enabled version of Siri. There have been competitors to MCP, but so far it’s been a standards war without any real battle — MCP has quickly taken over the industry. And now it’s official: This week, Anthropic is donating MCP to the Linux Foundation — and joining OpenAI, Google, Microsoft, AWS, Block, Bloomberg, and Cloudflare in establishing a new fund called the Agentic AI Foundation (AAIF), whose goal is to “advance open-source agentic AI.” The donation, and assigning a neutral body to govern MCP, will likely help supercharge its growth. It’s also a move that should change up how AI systems operate as we know it. For AI companies, MCP is the new standard for how these systems should access apps, tools, and information — and by extension, how people use the internet. […] MCP essentially tells AI models which external tools, data sources, and workflows they’re able to access, then allows them to connect and perform tasks. […] If you’re familiar with how computers generally worked before AI, this might all sound like a bunch of APIs — and you might recall that web apps and services opening their APIs to one another was the underpinning of the Web 2.0 era, and eventually the enormously lucrative explosion of mobile apps in the app store era. Moving users (and their money) from apps and websites to AI agents is one of the few ways AI companies can even begin to pay off their enormous investments. But AI agents need new kinds of APIs, and MCP seems like the standard those APIs will take. […] MCP started as a pet project by two Anthropic engineers, David Soria Parra and Justin Spahr-Summers. The initial goal wasn’t to build an industry-wide standard. The pair simply wanted Anthropic’s staff base to use Claude more in everyday work. […] Other Anthropic employees, it turned out, agreed with them. […] Krieger says that initially, his “dream case” for MCP was getting just one other frontier lab to adopt it. But widespread adoption came fast. On March 19th, Microsoft announced it would support MCP in its Copilot Studio. One week later, OpenAI CEO Sam Altman posted that “people love MCP and we are excited to add support across our products.” […] Anthropic isn’t the only company handing over something to the Linux Foundation. Block is donating Goose, its open-source AI agent, and OpenAI is donating Agents.md, which describes codebases to agents. Put the donations from Block, OpenAI, and Anthropic together, and the story is “about more than just MCP,” says Jackie Brosamer, head of data and AI at Block. “Protocols are essentially ways for systems to talk to each other, and that’s the most important thing to standardize.” […] Jim Zemlin, CEO of the Linux Foundation — the largest organization for open source and standards in the world — has been in the industry for more than two decades and has personally overseen the creation or expansion of a handful of new standards and platforms. But even he has been shocked by MCP’s grassroots growth. “I’ve never seen anything like this,” Zemlin tells The Verge. “I can barely keep up with the number of inbound calls from organizations who want to be a part of this. Usually I’m trying to convince someone, or scratching and clawing. This is really the reverse.” Josh Blyskal, who leads strategy and research for AEO (think: essentially SEO for AI) at Profound, believes MCP will “absolutely become a standard, especially in commerce,” and he says in a year, the way AI companies currently scrape websites will look “antiquated.”
