C is for Context. And that's not good enough for most people. "Context" gets confusing fast. Context window, context engineering, model context, server context... one word doing a dozen jobs. So we gave it a whole episode. @jlowin.dev and Radhika pull the meanings apart, one at a time. Link Below.

The DAG is dead. Long live the DAG. Same name, new job. The old workflow graph cared about how work got done. @jlowin.dev take at PyData London: graph the outcome. Stop auditing the loop and audit what falls out of it. Full keynote talk from PyData London below ⤵️
Running MCP with no gateway? Crazy. Running across the Grand Canyon and back? Somehow less crazy?! Fokke Dekker and Zach Angell talk Prefect Horizon, our enterprise MCP gateway, on Prefect's annual morning run before all-hands. Get a secure MCP server URL, free. Link Below →
We're in a new season of the FastMCP Pod and we're calling it Summer School. Everyone says "MCP gateway." Almost no one means the same thing by it. So we're going back to class. Jeremiah Lowin @jlowin.dev and Radhika Gulati get into what it actually is. Full Class recording in the comments ⤵️
Millions of people wake up and trust their WHOOP recovery score. WHOOP runs 5000+ jobs a day on terabytes of data. Prefect keeps it reliable. Carlos Peralta and Peter Belanger (WHOOP) played a round with the Prefect team to talk about what "data-driven" really takes. youtu.be/aSNjlOdiE6Q?...

Founder + CEO of Prefect. Creator of FastMCP (25k stars on GitHub). Father of four. Jeremiah Lowin @jlowin.dev also ships more code than most full time engineers. Radhika took him on a walk to ask HOW? Episode 4 of our walk-and-talks with the team building Prefect. www.youtube.com/watch?v=Axqu...
Jeremiah Lowin runs 5 Claudes at once. Here's the system behind it.

New headshots from the Prefect team, dropping today. Scientists call it the Pre-effect: a glow-up that kicks in once you join. Cause: immediate exposure to workflow automation. Effect? Undeniable.

We are taking the wheel... of your dbt DAG. In the demo below, see how the new Prefect dbt Orchestrator reads your project and runs it model-by-model. Demo and resources in the 🧵 www.youtube.com/watch?v=zH9l...

Friends don't let friends re-run unchanged SQL. It’s Day 2 of launch week and today we're launching the Prefect dbt Orchestrator. Every model, seed, test, and snapshot runs as a Prefect task. Caching, per-node retries, and the same alerting your other Prefect work uses.
Does running a Python function on Kubernetes just by adding @kubernetes on top of it sound too good to be true? Not to worry, we have a demo. Infrastructure Decorator resources in the 🧵 www.youtube.com/watch?v=Xyv8...

"Ramp moves fast. We need partners who do the same." Ryne Carbone and the team at Ramp moved 200 flows from Metaflow to Prefect in just 90 days. By the end of the quarter, they were managing 350+ flows with 70 active contributors. 🚀 www.youtube.com/watch?v=c0Jg...

We are taking @ to the next level. Day 1 of Launch Week is here, and we’re kicking things off with Infrastructure Decorators. Assign infrastructure directly in code, so each workflow runs on the compute it actually needs.

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. @jlowin.dev @aaazzam.bsky.social softwareengineeringdaily.com/2026/04/07/f...

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. Link below.
FastMCP 3.0 Beta is live 🚀 with a rebuild of the foundation. The foundation is rebuilt to move beyond simple tool scripts and into composable AI infrastructure. youtu.be/oN1xliDNWnQ?... 𝙼𝚊𝚓𝚘𝚛 𝚄𝚙𝚍𝚊𝚝𝚎𝚜 👇

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 ███████. This community got the first look before we let it loose on the world next week.
FastMCP v3 is coming. Jeremiah gives a sneak peek in this week's office hours, watch our latest podcast episode on YouTube below. Also: Py AI Conf Co-Hosted with @pydantic.dev March 10th, SF Guido van Rossum | @gvanrossum.bsky.social Sebastian Ramirez | @tiangolo.com Check it out at pyai.events

Travis Hoppe • 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 • @banjtheman.bsky.social • 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. • 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...

Prefect is proud to be a founding member of the newly established Agentic AI Foundation!
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...
