Anthropic donates Model Context Protocol to the Linux Foundation

Anthropic donated the Model Context Protocol to the newly formed Agentic AI Foundation under the Linux Foundation on December 9, 2025. MCP provides a standardized way for AI models to connect to external tools, databases, and data sources. It has been described as the 'USB-C for AI' because it creates a universal connector that works across different AI systems.

Three competing companies co-founded the Agentic AI Foundation: Anthropic, Block (formerly Square), and OpenAI. Despite battling for market share in AI, these rivals agreed to collaborate on shared infrastructure—following a historical pattern where competitors cooperate on standards while fighting over products, much like how rival browser makers jointly developed web standards.

Google, Microsoft, AWS, Cloudflare, and Bloomberg joined as platinum members, paying membership fees and gaining governance rights within the foundation. This breadth of corporate backing signals industry consensus that a shared standard benefits everyone—but also raises questions about whether the largest donors wield disproportionate influence over technical decisions.

Three founding projects anchor the foundation: MCP (Model Context Protocol) from Anthropic, goose (an open-source AI agent framework) from Block, and AGENTS.md (a specification for describing AI agent capabilities) from OpenAI. Each project addresses a different layer of the agentic AI infrastructure stack.

By the time of donation, MCP had already achieved massive adoption: more than 10,000 public MCP servers, 97 million SDK downloads per month, and over 75 connectors enabling AI systems to interact with tools and services ranging from developer platforms to Fortune 500 enterprise deployments.

Donating MCP to the Linux Foundation means no single company controls the standard. Governance follows the Linux Foundation's established processes—multiple stakeholder input, transparent decision-making, and community oversight—the same model that governs Linux, Kubernetes, and Node.js.

Founded in 2000, the Linux Foundation is a nonprofit organization that hosts many of the world's most critical open-source projects. Its governance model balances the interests of large corporate members with the broader open-source community, though critics note that corporate funding inevitably shapes priorities.
