Drive the Chrome the user is actually using (default profile, already-logged-in session) over the Chrome DevTools Protocol to perform web *actions* — clicking, liking/saving, commenting, filling forms, uploading files, submitting. Operates in background tabs so it never steals the user's focus, uses real mouse and keyboard events, and hands control back to the human whenever credentials, 2FA, CAPTCHA or payment confirmation are involved. Use when a task needs browser interaction…
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
# chrome-sidecar *A Chrome skill for AI agents: operate the user's real Chrome — in background tabs, with real input events, and with a handoff when a credential is required.* ## What it does Drives **the Chrome the user is already using**: same window, same profile directory, same logged-in sessions. It does not copy the profile, does not launch a separate debugging instance, and does not ask the user to change how they browse. **Use it when:** ① a task needs browser action (click / fill / upload / submit), or the user's existing login state avoids a re-login or 2FA wall; ② the user explicitly asks for CDP. The user does not have to say "CDP" — that is an implementation detail of this scope. **Do not use it for:** plain "look at / read this public page" requests. Those should use a normal page fetch or a throwaway Playwright instance — there is no reason to open a debugging port on someone's real browser to read a public page. ## Three rules that govern everything 1. **Never steal the foreground.** The user may be working in the same Chrome. New tabs are always created `background`. All interaction goes through CDP. **Never call `bringToFront` …

How to install
mdr add lcy362/chrome-sidecar/chrome-sidecar@sha256:57960fc25014ea74The line at the top of this page pins the label v1.0.0, 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.
