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. ...

Today, MCP turns one year old. You can check out the original announcement blog post if you don’t believe us. It’s hard to imagine that a little open-source experiment, a protocol to provide context to models, became the de-facto standard for this very scenario in less than twelve months. But not only do we hit the first anniversary milestone today - we’re also releasing a brand-new MCP specification version. Before we get to the details of what’s new, let’s do a bit of a retrospective. ...

The MCP Bundle format (MCPB) is now part of the Model Context Protocol project. This distribution format simplifies how developers package and share local MCP servers, enabling users to install them across any compatible client, including the Claude desktop app, Claude Code, and MCP for Windows. What are MCP Bundles? MCP Bundles are ZIP archives containing a local MCP server and a manifest.json that describes the server and its capabilities. The format is similar to Chrome extensions (.crx) or VS Code extensions (.vsix), enabling end users to install local MCP servers with a single click. ...

Many of us are still exploring the nooks and crannies of MCP and learning how to best use the building blocks of the protocol to enhance agents and applications. Some features, like Prompts, are frequently implemented and used within the MCP ecosystem. Others may appear a bit more obscure but have a lot of influence on how well an agent can interact with an MCP server. Server instructions fall in the latter category. ...
