Governance

MCP’s current spec release came out in November 2025. We haven’t cut a new version since, but the project hasn’t stood still. Over the past year MCP has moved well past its origins as a way to wire up local tools. It now runs in production at companies large and small, powers agent workflows, and is shaped by a growing community through Working Groups, Spec Enhancement Proposals (SEPs), and a formal governance process. None of that is news, but it’s the foundation we’re building on. ...

When MCP first launched in November of 2024, quite a few of its users relied on local environments, connecting clients to servers over STDIO. As MCP became the go-to standard for LLM integrations, community needs evolved, leading to the build-out of infrastructure around remote servers. There’s now growing demand for distributed deployments that can operate at scale. The Streamable HTTP transport was a significant step forward, enabling remote MCP deployments and unlocking new use cases. However, as enterprise deployments scale to millions of daily requests, early adopters have encountered practical challenges that make it difficult to leverage existing infrastructure patterns. The friction of stateful connections has become a bottleneck for managed services and load balancing. ...

Today marks a major milestone for the Model Context Protocol. Anthropic is donating MCP to the Agentic AI Foundation, a directed fund under the Linux Foundation. MCP will become a founding project of the newly created foundation. In one year, MCP has become one of the fastest-growing and widely-adopted open-source projects in AI: Over 97 million monthly SDK downloads, 10,000 active servers and first-class client support across major AI platforms like ChatGPT, Claude, Cursor, Gemini, Microsoft Copilot, Visual Studio Code and many more. ...

We’re updating how Specification Enhancement Proposals (SEPs) are submitted and managed. Starting today, SEPs will be created as pull requests to the seps/ directory instead of GitHub issues. Why the Change? When we introduced SEPs in July, we chose GitHub Issues as our starting point. Issues are familiar to developers, low-friction, and got us up and running quickly. But as more proposals have come through the process, we’ve identified some key pain points: ...

Since its open source release in November of 2024, the Model Context Protocol project has grown faster than we could have ever imagined. That’s a wonderful problem to have, but with growth come growing pains. Our existing processes, which worked well for a small team, have started to show their limits. Today, we’re taking a big step to ensure MCP can continue to grow and thrive. We’re introducing a formal governance model designed to bring clarity to the development process while preserving the collaborative, open source spirit that has made MCP successful. ...
