Drive a real browser from an Frontier FDE for prototype validation, web research, HTML output verification, and accessibility audits. Use when an agent needs to render JavaScript, click/type/screenshot a page, run an axe-core a11y audit, or read a JS-rendered page. Backed by Microsoft's Playwright MCP server (transport decided in ADR-342). Local-first, opt-in install.
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 > **When to load**: An Frontier FDE needs to render a page in a real browser, interact with it, capture a screenshot, run an accessibility audit, or read JavaScript-rendered content. Most commonly: UX Designer validating prototypes, Consulting Research reading SPAs, Engineer doing quick end-to-end smoke checks. > **DEFAULT test surface for UI-bearing changes**: Per the always-on rule in > `.github/instructions/project-conventions.instructions.md`, the agent browser > is the DEFAULT testing surface whenever a change renders UI or HTML. The > expected pass: render the running build, capture a snapshot/screenshot per > primary route, run an axe-core a11y scan, and drive at least one scripted > interaction per primary user task. Fall back to non-browser testing only when > no UI surface exists or the Playwright MCP server is unavailable -- and report > the missing prerequisite rather than silently skipping. ## When NOT to load - Static HTTP fetches (use the agent's normal fetch tool). - Bulk crawling, scraping behind auth, or anything outside the Frontier security profile's URL allowlist (see Anti-Patterns). …

How to install
mdr add jnpiyush/agentx/browser-automation@sha256:f4d5c48a365623e4The line at the top of this page pins the label git:20260923.68c041e, 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.
