We just published a near-term development roadmap for the model context protocol (MCP)Some highlights:- Remote support (and auth!)- Reference implementations- Better package management- Agent support pic.twitter.com/SflJi1RapH— Alex Albert (@alexalbert__) January 2, 2025
Explosive MCP Adoption in 2 Years
Den Delimarsky, lead maintainer of the Model Context Protocol and Claude Code engineer at Anthropic, delivers a keynote on MCP's two-year journey from a basic protocol with two SDKs to the industry standard powering half a billion downloads per month. - **MCP's Origin Story** - Launched in November 2024 with a spec, two transports (STDIO and HTTP), two SDKs (Python and TypeScript), and a handful of clients including Claude Desktop - **Five Spec Releases** - Every revision was driven by community input, improving security, adding OAuth support, and simplifying the developer experience for building MCP clients and servers - **The March 2025 Inflection Point** - A 14-day window when major industry players publicly backed MCP, signaling enterprise adoption beyond the early enthusiast community - **MCP 2.0 Release** - The biggest spec update since launch, removing sessions for stateless deployment on AWS Lambda and Cloudflare Workers, and introducing the extensions framework - **Extensions Framework** - MCP Apps, Tasks, and Enterprise managed apps can now be tested as extensions before being added to the core specification - **Explosive Growth** - SDK downloads grew 13x year-over-year, reaching 500 million per month and 3.06 billion cumulative across Python, TypeScript, and C# alone - **Registry Scale** - The open-source MCP server registry surpassed 20,000 entries, a 45x increase since its September launch - **10 Official SDKs** - From the original two, MCP now supports Go (Google), C# (Microsoft), Kotlin (JetBrains), Swift, Rust, and more, each sponsored by major platform companies - **Community Momentum** - 184,000 GitHub stars, 2,500+ unique committers, 736 PRs merged and 600+ issues solved last month alone Whether you are building your first MCP server or scaling agent infrastructure across your organization, this keynote lays out exactly where the protocol stands and where it is heading.
