The rate at which MCP support rolled out in the major vendor APIs is pretty astonishing: OpenAI added it May 21st, Anthropic launched theirs May 22nd and now Mistral have launched theirs on May 27th!My notes on the new Mistral announcement here: https://t.co/hmc0OfjFWQ— Simon Willison (@simonw) May 27, 2025

Yesterday @AnthropicAI announced the official MCP registry API at @aiDotEngineer 🎉This is fantastic news for us because we’ve wanted *the* source of truth. We made https://t.co/DQJVFx2J8P on day 1 to fill that gap for the community.Here’s what the API means for MCP and us... pic.twitter.com/tKDnbZqoV2— OpenTools (@opentools_) February 23, 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.

MCP-apps support is coming soon to @code Really excited about this - IDE as agentic SDLC C&C center - devs can stay focused even more inside their work and bring pieces of it to their IDE like JIRA/linear tickets and other tools right in the IDETnx @ConnorPeet pic.twitter.com/3fVpzRKjor— Oren Melamed (@OrenMe) January 5, 2026
The Creators of Model Context Protocol

MCP is mostly nonsense, but there are good effects:1. Tricks management to green-light engineering efforts on APIs and OAuth DCR (Dynamic Client Registration)2. Tricks LLM clients to integrate with everyone, ie an open-ecosystem, not walled gardens3. (Just discovered this…— Steve Krouse (@stevekrouse) November 12, 2025

MCP is a good protocol and it's rapidly becoming an open standard for the AI agentic era. We're excited to announce that we'll be supporting it for our Gemini models and SDK. Look forward to developing it further with the MCP team and others in the industry https://t.co/RAJH8J5zbB— Demis Hassabis (@demishassabis) April 9, 2025

.@AnthropicAI will support stateless remote MCP servers with “just HTTP” as transport.We’re quite excited about this! So we gave a “lightning talk” at an MCP meetup hosted by @paulgb @CloudflareDev yesterday. pic.twitter.com/ooZHus81cg— OpenTools (@opentools_) March 19, 2025

Recently, Anthropic https://t.co/v9hnbaLCmG and Cloudflare https://t.co/JBb6SexF8N released two blog posts that discuss a more efficient way for agents to interact with MCP servers, called Code Mode.There are three key issues when agents interact with MCP servers traditionally:… pic.twitter.com/hfUocpe6kV— Pietro (@pietrozullo) November 20, 2025
