MCP Night: Agent Mode — Not Just Another Tech Event

The theme of WorkOS’s latest MCP Night was Agent Mode — a familiar one for me, given we’re an AI-First company at Postman with a product by the same name: Agent Mode.

I’ve been attending MCP Night and the WorkOS suite of events since June 2025. These events mark real moments in a fast-moving industry — bringing together developers who are actively pushing the boundaries of what’s possible with AI. The last MCP Night was the Holiday Edition, where members of the Agentic AI Foundation discussed the “why” behind its formation, announced just the day before. Last week’s MCP Night: Agent Mode picked up where that left off, putting a spotlight on what can no longer be ignored: we are now building for agents as consumers, we are building at a mind-bending pace, and humans are inevitably moving up the stack.

It’s a theme that runs through the broader ecosystem — and close to home: two Postman companies, Fern and Astro AI, are building exactly this kind of agent-callable infrastructure. Fern generates agent-first SDKs and CLI tooling directly from API specs; Astro AI handles the deployment and operational layer for running agents in production.

Speaking of close to home — as swyx put it, roughly 80% of the world’s agents and AI engineering happens within 3 square miles of San Francisco. MCP Night is a core part of that — giving voice to the ideas, dilemmas, and energy of the people building it.

Big News: The Launch of auth.md

Michael Grinich, founder of WorkOS, opened with a keynote that set up everything that followed.

“Software has changed more in the last four months than in the past four years. No longer are we writing code by hand, no longer are we debugging things by hand. We are Masters of the Prompt.”

With agents taking on more decision-making, he announced auth.md — a new WorkOS product that gives agents a standardized way to register for services on behalf of users. It’s a small thing with big implications.

 

Lightning Demos: Love Them

One of the best parts of any MCP Night are the lightning demos from community members obsessed with finding out what’s at the edge. I was especially excited when Rys demoed his product, executor — a tool/source discovery and execution layer for agent-callable tools. The demo used PostHog, a company who will be demoing at the upcoming Postman Developer Agents and APIs meetup at Capital Factory in Austin on June 30th. Watch his demo here.

The Panel

The panel brought together a strong mix of perspectives on what technical leaders expect as agents become real decision-makers in business:

• Brendan Irvine-Broque, Sr. Director of Product, Cloudflare
• Claire Vo, Founder, ChatPRD
• David Cramer, Co-Founder & CPO, Sentry
• Michael Grinich, Founder, WorkOS

The entire conversation is worth checking out, but I give an extra stamp of approval on Claire Vo speaking up for the women who are running purchases for the household, and speaking to the value of allowing agents to purchase for us, to reduce admin overhead. I highly recommend watching the entirety of the panel here.

The After Party

The afterparty offered the well loved chess element, food, drinks, and comfortable opportunities to connect with others in the developer community. I definitely come for the content, and stay for the people, and the pork buns. Watch my short below for a view into the MCP Night after party experience.
