Browser

This is web automation that actually understands AI token constraints. The big win here is the element ref system: instead of dumping entire DOM trees into context, you get @e1, @e2 style references from accessibility snapshots, cutting context by 93%. You open a page, run snapshot with the -i flag for interactive elements only, then click @e2 or fill @e3 directly. It's built on agent-browser and exposes everything through MCP tools with the browser/ prefix. The session system lets you run parallel browser instances, which is neat for swarm patterns. If you're tired of context bloat from traditional Playwright or Puppeteer wrappers, this is the more surgical approach.
