Your AI Can Read the Web. Now It Can Use It.
Agent Browser runs a local automation engine that exposes 14 powerful MCP tools to any connected AI agent. Ask Claude to research a topic, fill out a form, log into a site, or extract clean content from a page — it handles the browser directly while you stay in the conversation.
Here’s What Claude Had to Say About Agent Browser
We asked Claude to stress test Agent Browser with no guidance. It ran 100+ operations across 10+ domains — navigation, JS execution, multi-tab orchestration, session persistence, even an infinite loop — with zero crashes.
“It’s a genuinely production-ready browser automation platform.” — Claude Sonnet 4.6

Why Agent Browser
Full Programmatic Multi-Tab Control
The first AI agent browser with automatic tab registration, provenance tracking, and agent-callable tab switching via MCP. Your AI knows which tab spawned which — and can navigate between them on demand.
Native Mac Menu Bar AI Browser
The first native Mac menu bar app that packages a full AI agent browser — with GUI, session management, and MCP — in one click. No terminal, no config files, no docker. Just launch and go.
Works With What You Already Use

Everything Your AI Needs to Control the Web
Not a scraper. A real browser engine with full scripting power.
Dual-Mode Operation
Headless Shell for speed and silence, or Real Chrome for sites that need fingerprint authenticity. Toggle with one call.
Session Persistence
Save and restore cookies and localStorage by name. Your AI stays authenticated across conversations — tested with 169 cookies, 3 origins.
Multi-Tab Awareness
Open, track, and switch between tabs. Full provenance tracking shows which tab spawned which — agents never lose context.
Clean Content Extraction
Fetch any URL as clean markdown — up to 67% fewer tokens than raw HTML. Optional Firecrawl integration for even cleaner results.
Host-Based Execution
Runs on your actual machine — real network access, real browser fingerprints, and access to sites that block sandboxed cloud browsers.
Real-Time Dashboard
Live run monitor at localhost:3210 with action logs, screenshots, and status. See every step your AI takes and why.
ARIA-Mode Snapshots
Token-efficient accessibility tree snapshots help agents find the right elements without processing full HTML.
100% Local & Private
All browser traffic, session data, and screenshots stay on your machine. No credentials sent to the cloud. No third-party browser control service.
Error Resilience
Invalid URLs, DNS failures, bad selectors, JS exceptions, even infinite loops — all caught gracefully with structured error messages. The browser always recovers.

How It Works
Four steps to browser automation.
Start from Menu Bar
One click starts all three services — MCP server, browser engine, and dashboard.
Auto-Connect
The MCP server connects to Claude Desktop or Cursor via stdio. One-click setup — no manual JSON editing.
AI Takes Control
Claude calls tools like navigate, snapshot, and act to control the browser directly.
Watch Everything
Screenshots, action logs, and results are stored locally and viewable in the real-time dashboard.
