Abstract
AI agents are only as strong as the infrastructure beneath them. In this talk, we’ll walk through the architecture behind Browserbase’s model context protocol (MCP), built to support stateful browser automation at scale. From concurrency models to session isolation, this talk dives into what it actually takes to run parallel agents in production, and what we learned the hard way. Expect live demos, real-world lessons, and infra blueprints you can steal.
Main Takeaways:
- Infra-first thinking is crucial for agent-based web automation.
- MCPs are not just tools, they’re runtime environments with real constraints.
- Attendees will leave with:
- Concrete patterns for scaling headless browser fleets.
- Security tips for managing cookies and sessions safely.
- Infra cost models and deployment blueprints.
- Hard-won lessons from production-scale orchestration.
Interview:
What is the focus of your work these days?
We’re building a stateful, concurrency-safe browser infrastructure for AI agents. Our focus is making multi-agent orchestration reliable, secure, and scalable—without abstracting away the parts developers actually need to control, like context and memory.
What is the motivation behind your talk?
Everyone’s excited about agents but very few talks get into the gritty, technical realities of running browser-based agents at scale. We wanted to share the behind-the-scenes of how infrastructure decisions shape performance, reliability, and developer experience. If you’re building agents that touch the web, this is the stuff no one’s documenting yet—but should be.
Who is the target audience for this session?
Chief Innovation Officers, Engineering Leads, AI Engineers, Technical Leads, etc.

Founder @Browserbase, previously Director of Self-Service & Engineering Manager @Mux, Co-Founder & CTO @Stream Club, Technical Lead @Twilio Inc.
Paul Klein IV is a San‐Francisco‐based serial entrepreneur and engineer. After honing his chops at Twilio during its IPO and founding Stream Club—a live‐streaming platform acquired by Mux in 2021. In 2024 he launched Browserbase to give developers and AI agents fast, reliable, multi‐region headless‐browser infrastructure. In its first 16 months, Klein raised over $67 million (from investors like Notable Capital, Kleiner Perkins, CRV, and Okta Ventures). He views Browserbase as the “last‐mile” interface between large language models and the web, enabling end‐to‐end workflow automation far beyond traditional scraping.
