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.

Introducing Prefab 🎨 A generative UI framework for building MCP Apps, data dashboards, or whatever you (or your agent) want. In Python. (Really.) 100+ shadcn components. Real React. No JavaScript required. And built right into FastMCP 3.2. prefab.prefect.io

Every single complaint I’ve seen about MCP is either people thinking the only possible use case is developers using it to augment Cursor (30%) or the result of using the most lazily built MCP servers known to man (70%) and deciding that it’s the protocol’s problem. @jlowin.dev also wrote about this

imo @jlowin.dev is doing god's work with FastMCP 3, making it super easy to unshittify MCP servers damn, should have a skill for unshittifying MCP 🤔

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.

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. 🧵

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

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...

How does a CLI command to transfer resources between backends relate to Kahn's algorithm and topological sorting? How can the looming threat of an LLM character takedown keep us accountable? These are questions that can only be answered in one place: dev-log.prefect.io

I can't emphasize this👇 too much. Our job is not to build the most sparkly "innovative" pie-in-the-sky "unicorn" idea. Maybe one in 10,000 of those take off, and I'm being conservative. Instead, address the pain. 1/3

The tragedy of venture capital: you raise it by pitching the smartest, most innovative ideas you can imagine. But you win customers by solving their dumbest, most annoying problems. That misalignment kills so many startups. So glad Prefect is now funded by the people who actually use it.
