This skill should be used when the user explicitly asks to "bootstrap CDP on Linux", "start Chromium on a headless box", "set up Xvfb for CDP", or "expose a CDP port in this sandbox". Launches Playwright-bundled Chromium under Xvfb with --remote-debugging-port so any CDP client can attach to a headed browser. Linux-only; user-invoked only.
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
# cdp-bootstrap Bring up a headed (Xvfb-backed) Chromium with a CDP port on a headless-Linux sandbox. This is the Linux path: the desktop browser routes (Claude in Chrome extension, codex's bundled chrome plugin) need a real desktop Chrome, and this skill is what stands in for one. Lifecycle is **start-only** — teardown and restart are the user's responsibility. ## Scope **WILL** - Start an Xvfb virtual display, then launch Playwright-bundled Chromium on top of it with `--remote-debugging-port` - Poll `/json/version` until reachable - Print the curl verification commands as the next step **WILL NOT** - Defeat the headed policy with `--headless=new` (no real visibility) - Stop or restart Xvfb / Chromium (use `pkill -f` manually) - Run on macOS (use the native launch in `references/cdp-endpoints.md`) - Install missing packages — if `xvfb` or chromium are absent, abort with a hint ## Execution ```bash bash .claude/skills/cdp-bootstrap/scripts/bootstrap.sh bash .claude/skills/cdp-bootstrap/scripts/bootstrap.sh --port 9333 --display 100 bash .claude/skills/cdp-bootstrap/scripts/bootstrap.sh --chrome /opt/google/chrome/chrome …

How to install
mdr add jongwony/cc-plugin/cdp-bootstrap@sha256:9a948edc6bce2947The line at the top of this page pins the label git:20261004.9dadfdb, 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.
