SAN FRANCISCO, Dec. 9, 2025 – The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced the formation of the Agentic AI Foundation (AAIF), and founding contributions of three leading projects driving innovation in open source AI; Anthropic’s Model Context Protocol (MCP), Block’s goose, and OpenAI’s AGENTS.md.
The advent of agentic AI represents a new era of autonomous decision making and coordination across AI systems that will transform and revolutionize entire industries. The AAIF provides a neutral, open foundation to ensure this critical capability evolves transparently, collaboratively, and in ways that advance the adoption of leading open source AI projects. Its inaugural projects, AGENTS.md, goose and MCP, lay the groundwork for a shared ecosystem of tools, standards, and community-driven innovation.
"We are seeing AI enter a new phase, as conversational systems shift to autonomous agents that can work together. Within just one year, MCP, AGENTS.md and goose have become essential tools for developers building this new class of agentic technologies," said Jim Zemlin, Executive Director of the Linux Foundation. "Bringing these projects together under the AAIF ensures they can grow with the transparency and stability that only open governance provides. The Linux Foundation is proud to serve as the neutral home where they will continue to build AI infrastructure the world will rely on."
MCP
The launch of the AAIF comes just one year after the release of MCP by Anthropic, provider of advanced AI systems grounded in safety research, including Claude and the Claude Developer Platform. MCP has rapidly become the universal standard protocol for connecting AI models to tools, data and applications, with more than 10,000 published MCP servers now covering everything from developer tools to Fortune 500 deployments. The protocol has been adopted by Claude, Cursor, Microsoft Copilot, Gemini, VS Code, ChatGPT and other popular AI platforms, as developers and enterprises gravitate toward its simple integration method, security controls, and faster deployment.
"MCP started as an internal project to solve a problem our own teams were facing. When we open sourced it in November 2024, we hoped other developers would find it as useful as we did,” said Mike Krieger, Chief Product Officer at Anthropic. “A year later, it's become the industry standard for connecting AI systems to data and tools, used by developers building with the most popular agentic coding tools and enterprises deploying on AWS, Google Cloud, and Azure. Donating MCP to the Linux Foundation as part of the AAIF ensures it stays open, neutral, and community-driven as it becomes critical infrastructure for AI. We remain committed to supporting and advancing MCP, and with the Linux Foundation's decades of experience stewarding the projects that power the internet, this is just the beginning."
goose
Released in early 2025, goose is an open source, local-first AI agent framework that combines language models, extensible tools, and standardized MCP-based integration to provide a structured, reliable, and trusted environment for building and executing agentic workflows. Developed and contributed by Block, the company behind Square, Cash App, Afterpay, TIDAL and a growing ecosystem of bitcoin projects, goose provides the practical infrastructure needed to advance agentic AI safely and consistently.
“We're at a critical moment for AI. The technology that will define the next decade, that promises to be the biggest engine of economic growth since the Internet, can either remain closed and proprietary for the benefit of few, or be driven by open standards, open protocols, and open access for the benefit of all,” said Manik Surtani, Head of Open Source at Block. “By establishing the AAIF, Block and this group of industry leaders are taking a stand for openness. goose was our first step; establishing the AAIF and contributing goose to it ensures that agentic AI remains shaped by the community and driven by merit. Together, we're building the infrastructure for an AI future that benefits everyone."
AGENTS.md
Released by OpenAI in August 2025, AGENTS.md is a simple, universal standard that gives AI coding agents a consistent source of project-specific guidance needed to operate reliably across different repositories and toolchains. This markdown-based convention makes agent behavior far more predictable across diverse repositories and build systems. AGENTS.md has already been adopted by more than 60,000 open source projects and agent frameworks including Amp, Codex, Cursor, Devin, Factory, Gemini CLI, GitHub Copilot, Jules and VS Code among others. OpenAI was an early adopter of MCP and has contributed ACP, Codex CLI, and the Agents SDK and Apps SDK to support the open agentic ecosystem, building on shared, interoperable protocols.
“For AI agents to reach their full potential, developers and enterprises need trustworthy infrastructure and accessible tools to build on. By co-founding the AAIF and donating AGENTS.md, we’re helping establish open, transparent practices that make AI agent development more predictable, interoperable, and safe,” said Nick Cooper, Member of the Technical Staff at OpenAI. “OpenAI has long believed that shared, community-driven protocols are essential to a healthy agentic ecosystem, which is why we’ve open sourced key building blocks like the Codex CLI, the Agents SDK, and now AGENTS.md. We’re proud to work alongside our co-founders to advance a more open and trustworthy future for agentic AI.”
Platinum members of the AAIF include Amazon Web Services, Anthropic, Block, Bloomberg, Cloudflare, Google, Microsoft and OpenAI. Gold members of the AAIF include Adyen, Arcade.dev, Cisco, Datadog, Docker, Ericsson, IBM, JetBrains, Okta, Oracle, Runlayer, Salesforce, SAP, Shopify, Snowflake, Temporal, Tetrate, and Twilio Inc.

“Open standards and protocols like MCP are essential to enabling a thriving developer ecosystem for building agents – they ensure anyone can build agents, across platforms, without the fear of vendor lock-in. Since the introduction of MCP we’ve been collaborating closely with Anthropic to be among one of the first in the industry to support remote MCP. We’ve seen an explosion of remote MCP servers, many of them built on and deployed to Cloudflare over the past year. Joining the Agentic AI Foundation will enable Cloudflare to continue our work to support standards and push the ecosystem forward with new ideas like Code Mode.”
– Dane Knecht, Chief Technology Officer, Cloudflare
"Google has championed open source for decades because we know that for new technology to get widely adopted, we need shared standards. That’s why we’re backing the Agentic AI Foundation. We want to help build a system where developers can trust that whatever they build in this new domain is interoperable. By collaborating on neutral ground, we can make sure this technology grows in a way that helps developers and – most importantly – people. It’s all about keeping innovation open and giving the community real choices."
– Richard Seroter, Chief Evangelist and Head of Open Source Programs, Google Cloud
“For the agentic future to become a reality, we have to build it together, and we have to build it in the open. The AAIF will give industry and developers a shared and transparent path to evolve the agentic AI ecosystem. Microsoft remains committed to supporting this journey to create an open, interoperable and reliable foundation for everyone building and using agents.”
– Chris DiBona, VP, Office of the Chief Technology Officer, Microsoft
