iiinova — where your digital self keeps evolving

Lastly, we're already working on FastMCP 3.1 with a new take on MCP Apps. I think it might be a bigger deal than 3.0.

GitHub - PrefectHQ/fastmcp: 🚀 The fast, Pythonic way to build MCP servers and clients.

FastMCP is downloaded over a million times a day. We regret that some of you are about to be surprised by an unexpected upgrade. If it causes any issue, we're sorry. The upgrade guides will help, and if something's broken, please open an issue: github.com/prefecthq/fa...

Upgrading from FastMCP 2 - FastMCP

You already know this was our biggest release ever, but during its month-long beta, FastMCP 3 attracted 21 first-time contributors and over 100K opt-in installs. The paint is still wet on the overhauled docs and upgrade guides (just ask your LLM!) gofastmcp.com/getting-star...

Most of the work went into rearchitecting the framework to be production-ready for where MCP is going in 2026. But if we did our job right, you shouldn't be able to tell. You'll just notice everything works *better*. www.jlowin.dev/blog/fastmcp...

FastMCP 3.0 is GA

FastMCP 3.0 is out! I don't even know how to fit it in a post... 🔌 Build servers from directories, APIs, remote servers — anything 🎭 Per-session context & progressive disclosure 🖥️ Full CLI: list, call, generate clients 🔐 Versioning, granular auth, OTEL ⚡️ DX galore

New Episode of chatting with Prefect's Builders - @jlowin.dev chats with with @aaazzam.bsky.social about FastMCP's path from weekend project to the most popular open source thing we've built. Also: why "automation" is a better word than "orchestration." Hope you get outside today. Link below.

Actually Colin has a MCP-to-skill template. Probably needs some work

Oh no! Would love to learn from your experience. Tool transforms started life in 2.0 as part of Bill Easton’s campaign for sanity so this is a bit of a formalization of that

Migration instructions for upgrading between FastMCP versions

There's A LOT here, but we've tried extremely hard to keep breaking changes minimal. Most users will not need to change their code at all. You can read the full upgrade guide here: gofastmcp.com/development/... Happy (context) engineering!

And by popular demand, we’ve polished the developer experience: ⚡ Servers support hot reload during development ⚡ Decorators now return callable functions (finally!) ⚡ Automatic threadpools for sync tools

The new architecture lets us ship a massive number of features: 🎁 Custom providers like filesystems and remote APIs ✨ Per-component authorization 🏷️ Component versioning 🧠 And even skills over MCP...! Read the comprehensive feature guide here: www.jlowin.dev/blog/fastmcp...

We're moving past "tool servers." Source from anywhere. Compose and transform freely. Personalize per-user. Track state across sessions. Control access. Run long operations. Version your APIs. Observe everything. We call this the context era: www.jlowin.dev/blog/fastmcp-3

Move fast and make things.

FastMCP 3.0 is here! This is our largest and most ambitious release ever. We've re-architected the framework to support the next generation of MCP applications. It's time to move fast and make things. 🧵

Kudos again to the @prefect.io crew on doing documentation right for the AI era. I love everything about this -- mcp server, llms.txt and copy as markdown shortcut behavior

$The FastMCP documentation is available in multiple LLM-friendly formats: MCP Server The FastMCP docs are accessible via MCP! The server URL is https://gofastmcp.com/mcp. In fact, you can use FastMCP to search the FastMCP docs: Copy import asyncio from fastmcp import Client async def main(): async with Client("https://gofastmcp.com/mcp") as client: result = await client.call_tool( name="SearchFastMcp", arguments={"query": "deploy a FastMCP server"} ) print(result) asyncio.run(main()) Plain Text Formats The docs are also available in llms.txt format: llms.txt - A sitemap listing all documentation pages llms-full.txt - The entire documentation in one file (may exceed context windows) Any page can be accessed as markdown by appending .md to the URL. For example, this page becomes https://gofastmcp.com/getting-started/welcome.md. You can also copy any page as markdown by pressing “Cmd+C” (or “Ctrl+C” on Windows) on your keyboard.$

This is the most compelling argument I've seen thus far for MCP.

In a recent post, @chris.blue argues that MCP is an unnecessary and temporary kludge on the decline and facing an uncertain future. IMO it standardizes how agents have stateful, identity-aware conversations. aaazzam.substack.com/p/the-apolog...

As an open-source maintainer, one of the hardest things is saying "no" to well-designed features that are simply not a good fit. With LLMs able to generate volumes of code without context, the maintainer's role as a thoughtful curator has never been more important. www.jlowin.dev/blog/oss-mai...
