straight from dbt summit 2026: we asked our floor reps what customers wanted to talk to them about. watch what they heard about ai agents, data freshness, and mcp servers last week in vegas.

It’s almost time for dbt Summit 2026, and we’ve got Prefect, Dagster, and FastMCP people all in one booth. Find us for demos, conversations about orchestrating dbt, data assets, MCP, and a****** workflows. + some customizable swag Link in comments for more. *The a-word is agentic, obviously.

"I'm something of an admin myself." On the latest episode of FastMCP Pod, Jeremiah Lowin walks through MCP authentication / authorization and how FastMCP actually checks you out. Full episode in the comments below ⤵️

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?...

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)

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.
