Anthropic is donating the Model Context Protocol to the Agentic AI Foundation, a directed fund under the Linux Foundation. In one year, MCP has become a foundational protocol for agentic AI. Joining AAIF ensures MCP remains open and community-driven. www.anthropic.com/news/donatin...

I am so stoked to see what Benjamin, Austin, David and @steveklabnik.com going to build. I just love source control problems so much and really looking forward to a company shaking it up.

MCP Spec 2025-11-25 Release Candidate: Upcoming additions are Tasks, enabling long running operations, and Client ID Metadata replacing Dynamic Client Registration as well as lots of small ergonomics. Take a look and give us feedback in our discord and issues. modelcontextprotocol.io/specificatio...

Another disappointment this year …

We need a central registry for all MCP servers. So we build a central registry API. See the announcement at blog.modelcontextprotocol.io/posts/2025-0.... It is importing that we want a central place but also want the ecosystem to offer curated, or private registries on top. That’s what you can do

Very funny how Labour is just a far right party now.

I sat down with Theo and @alexalbert.bsky.social to talk about MCP at @anthropic.com HQ. If you want to hear tidbits about the history, what's next for MCP, or just want to watch me awkwardly moving back and forth on the chair trying to hold a conversation, here is the video:

Thanks to Shopify, MCP now has an official Ruby SDK. It's still early and a few pieces are missing, but go check it out: rubygems.org/gems/mcp.

Spring AI 1.0.0-RC1 and MCP Java SDK 0.10.0 just released! 🚀 Check release notes: - Spring AI: spring.io/blog/2025/05/13/spring-ai-1-0-0-RC1-released - MCP Java SDK: github.com/modelcontextprotocol/java-sdk/releases/tag/v0.10.0 #SpringAI #MCP

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust. In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

VSCode is on the bleeding edge of MCP development. So great to see the most popular editor being amazing MCP adopters

Wanna to make an MCP server for your API but you have a gazillion endpoints?! Check out this layering approach used to create the Square MCP. With only 3 MCP tools, we expose 30+ APIs and 200+ endpoints! 🤯 engineering.block.xyz/blog/build-m...

New in 1.98: Model Context Protocol (MCP) 🔌 Connect Raycast AI to external systems and data sources 💬 @-mention MCP servers in AI Chat, and everywhere else 🧭 Discover MCP servers with our new registry extension Full changelog 👉 raycast.com/changelog/1...

So hyped to try this. I have tried all the editors, and as much as I like cursor and windsurf, Zed still is the one I am coming back to the most. So looking forward to trying this.

Okay I am slacking on BlueSky, and need to spent more time here. Anyway, super stoked that remote mcp servers are now a thing in Claude.AI. It's something we have hoped to build forever and I am so stoked what the team has built there: www.anthropic.com/news/integra...

Model Context Protocol might be the answer to debug your vibecoded masterpiece. I dive deeper with @cloudflare.social, a custom #opentelemetry collector written in Rust, and @cursor.com.web.brid.gy : fiberplane.com/blog/hono-ot...

Today marks one year at Anthropic. I couldn’t be happier. It’s such an amazing place and so many great people to learn from.

Want to use C# to build an MCP server or an AI application that connects to MCP servers? Then you should check out the new MCP C# SDK. Read all about it in my new blog post: devblogs.microsoft.com/blog/microso... #dotnet #mcp

📣 This just in... The *open source* and official GitHub MCP Server is here 🤩 github.blog/changelog/20...

We finally have an official C# SDK for MCP. This one is sponsored by Microsoft! devblogs.microsoft.com/blog/microso...

I have been playing around with the new C# MCP SDK allowing you to easily create servers and clients in minutes. It is fantastic! github.com/modelcontext... #mcp #mcpserver #csharp #dotnet

With all the MCP hype, we went ahead and built an MCP server for Playwright. Ours is snapshot-based, which makes it faster and more reliable! You can opt into the visual mode too. Have fun! 🚀 #Playwright #MCP github.com/microsoft/pl...

What the fuck is happening..,

As founder of #MCP Java SDK and co-lead for #SpringAI, bringing these technologies together has been exciting. I'm grateful to @jetbrains.com for the highlight! Big thanks to the Spring community and @thedsp.bsky.social for the amazing support! Can't wait to see what developers build! 🚀

Claude Sonnet 3.7 with Claude Code has been a great help pairing with me on MCP SDK work. So stoked to see what people will build with it. www.anthropic.com/news/claude-...

Community contributions are 🔥 During a past livestream, Aaron Goldsmith, Infra Ops Eng @ Cash App, showed a team of Goose AI agents collabing in real time to create a website. Our community loved it so much, community member Cliff Hall was inspired to iterate and create a GooseTeam MCP server! 🤯

Okay this is looong I wanted to really break it down to make it understandable + actionable New blog post on extending AI chat with Model Context Protocol, and why it matters interconnected.org/home/2025/02...

Step 1 of Claude buying my Steam games: Recommendations asciinema.org/a/mWLGGT29pR...

If MCP protocol from Anthropic succeed, it will democratize the connector market, and the ones who claimed that they have "100+s" connectors will loose their moat. Everyone will get access to everything. Can't wait for its server support with Auth!

The Model Context Protocol (MCP) fundamentally changes what's possible. Rather than being limited to predefined integrations, teams can extend capabilities through custom tools: >Internal monitoring integration >Security scanning workflows >Documentation automation

🎉We are pleased to announce that the Java MCP SDK developed by Spring AI is becoming the official MCP Java SDK!🎉 spring.io/blog/2025/02... As the MCP core team, we are happy to have an SDK for Java that feels like Java and fits perfectly into the wider Java ecosystem such as Spring AI.

Join me at Amsterdam JUG for "From LLMs to Agents: Transforming Applications with MCP and Spring AI": meetup.com/amsterdam-ja... We'll talk about how the Model Context Protocol (MCP) facilitates the AI agent development. Live coding with #SpringAI & #MCP

How I debug MCP STDIO servers:

FWIW we Rust folks should be a little more forthcoming in saying that the load is not zero—but also that that's fine, the benefits are worth it. I'm worried saying zero load burns credibility

Cursor now supports the Model Context Protocol (MCP). Get ready to see some cool stuff!

Anthropic's MCP standard is getting a lot of buzz, and rightfully so. I cannot overstate how much this unlocks for AI tools! Check out my latest blog post to learn more. block.github.io/goose/blog/2...

Take a look at Goose. It’s exciting what block has built and best, you can tap into the hundreds of available MCP servers with it

Our newest project is taking flight: meet codename goose! 🪶 Today, we launched an open source on-machine AI Agent. It’s modular, works with your preferred LLM, and integrates seamlessly with developer tools and other software via MCP. Developers, check it out! block.github.io/goose/blog/2...

Oh man, I sometimes wish I could just give a tiny gimps into all the ongoing cool stuff that <unnamed> companies work on MCP related stuff. Next few months going to be wild.

Claude Converses With Neo4j Via MCP 😀 As Anthropic published a new Model Context Protocol (MCP) for LLMs like Claude to communicate with external data sources, Michael started implementing a #Neo4j MCP server to see what that would look like- the results are interesting! bit.ly/401RBRZ

After learning about Model Context Protocol (MCP), a way to expose external software to LLMs, I decided to experiment with it! 🧪 You can read all about it on my latest blog post: tomcools.be/post/2025-ja... Thanks @maxandersen.xam.dk for the explainer on how to do this in #quarkus. #java #camel

Oh my, I know quite a bit about systems, and REALLY should know better, but here we go. I lost my mastodon database and had no backups. Quite embarrassing, but there we go.

If you have considered adding MCP support to your interfaces and frameworks but chose not to yet, tell me why!

I am looking for passionate software engineers who have experience in maintaining Open Source projects, and want to work on Model Context Protocol for a few months. You would have a strong track record of open source contribution, care about AI safety and know TS and/or Python

So this just happened. I have to say, I am proud of what we have built and the reception we have gotten. Tobi is an inspiring technologist and him being positive about MCP means a lot. Let's go

Huge news for people who like building MCP servers! Extremely grateful to @thedsp.bsky.social for his gracious assistance in bringing FastMCP into the official SDK.

This is a big one: Python MCP SDK 1.2.0 is out! The best part? It contains the widely used FastMCP library as part of the SDK. Don't worry, the old code still works and there is no need to update, but writing new servers is much easier. Check out the release notes: github.com/modelcontext...

Excellent, a new major release of axum. Time to get real confused by compiler errors.

Atuin is amazing and I install in every system I can. What @ellie.wtf has created is true delight.

Atuin v18.4 is out now! Including `atuin wrapped`, your year in shell history 🐢 thanks @daveeddy.com for the suggestion!
