Use Chrome DevTools MCP to control and inspect a live Chrome instance for network, console, performance, rendering, and Deep debugging. Pairs with playwright-cli (deterministic interaction/E2E) — complements, not duplicates.
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 DevTools Control and inspect a **live Chrome** browser via the official `ChromeDevTools/chrome-devtools-mcp` (`chrome-devtools-mcp`, Apache-2.0) MCP server. Gives your coding agent the full power of Chrome DevTools for **runtime debugging, network inspection, performance analysis, and rendering diagnostics** — while `playwright-cli` remains the primary tool for deterministic interaction and E2E validation. > **Complementarity:** `playwright-cli` → deterministic `locator/snapshot/assert` workflows, multi-tab, traces, screenshots. `chrome-devtools` → network + console + performance traces + rendering diagnostics + Puppeteer-based reliable automation via DevTools. **Do not** re-implement Playwright flows via DevTools JSON-RPC; pick the right provider per capability (see decision table). ## When to use which provider | Need | Use `playwright-cli` | Use `chrome-devtools` | Either | |------|----------------------|-----------------------|--------| | Click / fill / navigate deterministically | ✅ locators, `snapshot` → stable `eN` refs, fixtures | — | | …

How to install
mdr add ulises-jeremias/agent-toolkit/chrome-devtools@sha256:81a9dbb9ba16bb36The line at the top of this page pins the label git:20260831.856ee57, 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.
