Drive a real browser from the shell with Playwright CLI - open pages, click, fill forms, read the DOM, screenshot, inspect console and network. Use whenever a task needs a live browser (reproduce a UI bug, verify a frontend change, check a page renders, log into a site, scrape a page) AND no browser MCP tools are available (no mcp__playwright__*, no mcp__claude-in-chrome__*). Also use when explicitly asked to "use the browser-cli skill".
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 without MCP `playwright-cli` is a stateful browser driver you call as ordinary shell commands. One browser session stays alive **between** commands, so you drive it one step at a time and read the page after each step — the same loop a browser MCP gives you, but over Bash. ## 0. Make sure the CLI exists ```bash playwright-cli --version || npm install -g @playwright/cli@latest ``` ## 1. The core loop ```bash playwright-cli open http://localhost:4200 # starts the browser + navigates playwright-cli snapshot # read the page, get element refs (e12, f1e56, ...) playwright-cli click e15 # act, using a ref from the snapshot playwright-cli close # always close when done ``` Every command prints the page URL, title, and a fresh **snapshot** — an accessibility tree where each element carries a `[ref=...]`. **Refs are how you target elements.** Take a `snapshot` first; never guess a ref. Snapshots are written to `$PLAYWRIGHT_MCP_OUTPUT_DIR/page-<timestamp>.yml` — this repo pins that to `/tmp/playwright-cli` in `.claude/settings.json` so the scratch files never land in the working tree.

How to install
mdr add victorrentea/petclinic/browser-cli@sha256:c63b5ab30d10c12cThe line at the top of this page pins the label git:20260812.926728b, 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.
