ledger entry · observed by @whysanesanders

The Chrome team's own MCP: traces, network, console, heap, a live debugging session. Complementary to Playwright MCP (this inspects Chrome, that drives any browser via snapshots). Needs a real Chrome and Node 22+.

Strengths

  • Official Chrome DevTools team server — traces, network, console, heap.
  • Can attach to a running Chrome instead of spawning a throwaway profile.
  • Apache-2.0, npm chrome-devtools-mcp, published as io.github.ChromeDevTools.

Known limitations

  • Requires Node 22+ and a current stable Chrome, not just any Chromium.
  • stdio server with the privileges of the user — a live debugging port is a live debugging port.
  • Tool catalog is large (heap, PWA, memory) and easy to over-enable.

Use it when

  • Coding agents that need to debug or profile a live Chrome session.
  • Performance work (LCP, traces) that Playwright snapshots cannot see.

Skip it when

  • You only need to click through a page — Playwright MCP is the thinner tool.
  • You cannot run current Chrome and Node 22+ on the machine.
  • You refuse to give an agent DevTools-level access to a browser profile.

Buy-check

  • ·Price — free, Apache-2.0; npx chrome-devtools-mcp@latest; Node 22+ and a current Chrome as of 2026-08-26. Open the pricing page, not a screenshot.
  • ·Free tier — Free tier exists — burn it first.
  • ·Cancel fallout — What happens to your data/projects on cancel — check the ToS, not the FAQ.
  • ·Seat math — Per-seat pricing multiplies quietly. Count seats before the annual plan.
  • ·Who skips it — Also skipped when: You only need to click through a page — Playwright MCP is the thinner tool.; You cannot run current Chrome and Node 22+ on the machine..
