Model Context Protocol

One of the defining qualities of MCP has always been its ecosystem - clients and servers built to interop with each other. As the protocol grew, we saw a clear opportunity to keep the core stable while also providing avenues for extensibility. This is where MCP Extensions come in. 🧩 MCP just got more modular. Extensions let us plug optional capabilities into the protocol - auth, UI, or industry-specific logic - without bloating the core spec. 🔐 Enterprise-ready from day one. Official extensions already cover OAuth client credentials, centralized enterprise auth, and MCP Apps for interactive UI elements right inside conversations. 🧪 Got an idea? There's a path for that. Experimental extensions let MCP Working Groups prototype and iterate before going through the formal approval process to become official. 🤝 Built to play nice. Clients and servers negotiate extension support during initialization, with graceful fallbacks so nothing breaks if one side doesn't support a feature. You can learn more about what extensions are and how they work in our official docs: https://lnkd.in/gQWy9grF #mcp #modelcontextprotocol #ai #artificialintelligence #oss #opensource #devex #developerexperience #extensions

The fastest way to get started with MCP Apps is by going to the official extension repository on GitHub! That's where you will get pointers to everything you need to build your first app (and make that as easy of a process as possible). ✨ Pointers to quickstarts and API docs for your (and your agent's) reading pleasure 🚀 A handy agent skill that will help you build the app in no time 🏗️ More than a handful of samples to show you what's possible out-of-the-box Check it out ⮡ https://lnkd.in/ggdME37k And of course, if you have any feedback - open an issue! #mcp #modelcontextprotocol #ai #artificialintelligence #apps #mcpapps #ui #ux #webdev #engineering #tech #devex #agents

Just a couple of weeks ago we launched MCP Apps - the open extension to the protocol that enables anyone's MCP server to also provide rich UI to clients they're connected from 🖼️ If you're curious about building your own MCP Apps, we have a handy guide that will help you get started in no time 🤯 Worry not, because if you want to get started even quicker, there's an agent skill available as well - just plug it into your agent of choice and the app scaffolding will be built for you ✨ Read ⮡ https://lnkd.in/ddab5dka #mcp #modelcontextprotocol #ai #artificialintelligence #apps #mcpapps #ui #ux #webdev #engineering #tech #devex #agents

Starting today, you can embed interactivity into your MCP experiences with the help of the first official extension - MCP Apps 🎉 Build on the foundations of the work of MCP-UI and OpenAI Apps SDK, you now have a shared way to go beyond text and build fully-featured (and fully-functional) UIs that can be rendered in MCP clients supporting the extension - all on top of existing MCP primitives 🤩 We're also excited to see how MCP Apps light up across the ecosystem, with future client support from OpenAI, Block, Microsoft, JetBrains, Amazon Web Services (AWS), and Google DeepMind.

MCP is starting the year with an update to the Core Maintainers roster. First of all, we'd like to thank Inna Harper and Basil Hosmer, who will be stepping away from the Core Maintainer team to focus on other projects. Inna and Basil have been with MCP since its early days and their contributions made the protocol what it is today. They helped with some of the key architectural decisions as well as drove the design and delivery of our official SDKs. Their work is reflected in all major spec releases and we're incredibly grateful for their contributions. We'd also like to welcome three new members to the Core Maintainer group, who will help steer MCP, in addition to the existing crew: - Peter Alexander, Member of Technical Staff at Anthropic - Caitie McCaffrey, Software Engineer & Tech Lead at Microsoft - Kurtis Van Gent, Senior Staff Software Engineer at Google We're excited to continue working together to help shape the future of MCP and collaborate with our (extremely broad) community of developers, early adopters, and advocates! https://lnkd.in/gxfEEQ8e #modelcontextprotocol #mcp #ai #artificialintelligence #oss #engineering

It's officially the first anniversary of Model Context Protocol 🎉 Thank YOU for helping us craft the protocol for the past year - all those contributions to the spec, documentation, samples, servers, developer tooling, and clients allowed the protocol to become what it is today. We simply could not have done this without you 🥰 And what better birthday thing we can do than release a brand-new version of the MCP specification - 2025-11-25 is now live! This specification introduces: 🔒 Client ID Metadata Documents (CIMD) for authorization, superseding Dynamic Client Registation (DCR). ⏳ Experimental support for Tasks, enabling tracking durable requests with polling and deferred result retrieval. 💬 Support for URL mode elicitations, giving servers the flexibility to provide URLs where users can complete authorization or any other interactive transaction. 🧩 Enhance authorization flows with incremental scope consent. 🔌 Extensions, allowing us to quickly ship and validate protocol changes without breaking the core spec. There's so much more that we're excited about - read about it in our announcement blog post: https://lnkd.in/gWDQU6wJ #mcp #modelcontextprotocol #ai #artificialintelligence #opensource #oss
