Ethan Rosenthal (@ethanrosenthal.com) , Senior ML Engineer at Runway spent ten years watching every ML project follow the same path: script, CLI, config file, Turing-complete YAML nightmare. He built Confingy to solve that problem.

Tip: if you use a package from GitHub heavily, you can subscribe to find out about new releases (but not get overwhelmed by other notifs).
I just did that for FastMCP since their releases are always chock full of new features.
(Also I love their punny release titles)
Jeremiah Lowin is the founder and CEO of @prefect.io, and Adam Azzam is the VP of Product. They join Gregor Vand to discuss fastmcp, its origin story, core framework pillars, and FastMCP 3.0 architecture.

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.

New podcast episode on MCP apps and what we're learning as this unfolds.
The interesting question is where this goes next. We're recording these knowing things will shift and that's the point. Figure it out in public, see what sticks.

π‘ Agent Skills: Direct instructions on how and when an agent should use specific tools.
π±ππππ πππ π²ππππππππππππ’: The core Pythonic API remains the same. This rebuild adds the infrastructure required for dynamic environments without breaking your current v2 servers.
𧩠Composite Apps: Combine tools from data, platform, and product teams into one authorized interface without collisions.
π Context Optimization: New features for search, curation, and progressive disclosure to keep agent context windows clean.
π Provider Architecture: A unified system that replaces duplicated code across features for flexible, dynamic server building.
π€ Dynamic Scoping: Servers can now show different tools to different users from a single endpoint.
FastMCP 3.0 Beta is live π with a rebuild of the foundation.
The foundation is rebuilt to move beyond simple tool scripts and into composable AI infrastructure.

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.

Py AI DC brought out a phenomenal crowd last night, proof that the DC Python community is building the future of AI one meetup at a time.
That's why we couldn't resist showing them Prefect βββββββ. This community got the first look before we let it loose on the world next week.

Travis Hoppe β’ Acting Chief AI Officer @ the CDC rounds out our guest speakers for our sold out Py AI DC.
March 10 in SF: Py AI Conference is the big one. Only 300 spots to hear top-tier Python + AI speakers. The kind of lineup you book flights for. Both links in comments below.
The Py AI series is all about short talks, honest demos and real conversation. No one's selling you anything - just ideas you can take back to your project next day.
Banjo Obayomi β’ @banjtheman.bsky.social β’ Senior Specialist Solutions Architect GenAI @ AWS joins us for Py AI DC.
Co-hosted with @pydantic.dev, Py AI is where people building with Python and AI actually talk about what they're working on.
SF, NYC, London. Now it's DC's turn.
Roni Kobrosly, Ph.D. β’ Director of Data Science @ Capital One kicks things off.
More details dropping soon. RSVP in the comments.
We're having conversations with the team about building Prefect. Whatever comes up.
This time with Engineers Nate Nowack (@zzstoatzz) and Alex Streed (@desertaxle). Designing for coding agents, the Prefect MCP server and the Pydantic AI integration. www.youtube.com/watch?v=qTT1...
Open source is core to how we build. FastMCP has been part of MCP's growth from the beginning, now downloaded over a million times a week!
We're joining the AAIF because the future of agentic AI should be open, trusted, and built by the community that uses it.
The AAIF, a directed fund under the Linux Foundation, was established by Anthropic, Block, OpenAI, Google, Microsoft, AWS, Cloudflare, and Bloomberg. Today, Anthropic announced they're donating the Model Context Protocol (MCP) to the foundation.
Prefect is proud to be a founding member of the newly established Agentic AI Foundation!
