Drive Browserbase cloud browser sessions via the browse CLI when local automation is blocked. Use when a site throws CAPTCHAs (reCAPTCHA, hCaptcha, Turnstile), bot-detection walls, Cloudflare interstitials, HTTP 403/429, or geo blocks - or when the user asks for Browserbase, residential proxies, Browserbase Identity, Verified browsers, automatic CAPTCHA solving, or persistent cloud login via Browserbase contexts.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Browser Automation (Browserbase Remote) Drive Browserbase cloud browser sessions with the browse CLI. This skill is remote-only: every session runs in Browserbase's cloud with Identity, Verified browsers, automatic CAPTCHA solving, residential proxies, and persistent contexts. For local browser automation - localhost, dev flows, your own Chrome profile - use the `agent-browser` skill instead. ## When to Escalate Here This is the documented escalation path from `agent-browser`. Switch a run to a Browserbase session when the local browser hits: - CAPTCHAs: reCAPTCHA, hCaptcha, Turnstile - Bot-detection pages: "Checking your browser...", Cloudflare interstitials - HTTP 403/429, or empty pages on sites that should have content - Geo blocks that need residential proxies (201 countries, geo-targeting) - Sites that require a Verified browser via Browserbase Identity - Auth that must persist across sessions in the cloud (Browserbase contexts) - The user asks for it Don't escalate for simple sites (docs, wikis, public APIs) or localhost - stay on `agent-browser`. ## Setup check Before running any browser commands, verify the CLI is available: ```bash …

How to install
mdr add vanducng/skills/browser@sha256:09d8a9d95f777ae2The line at the top of this page pins the label git:20260911.9e58ef3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
