Chrome DevTools MCP BB

Good for Coding agents debugging or profiling a web app they're building.

Ahead on

  • Reliability, 83 against 57
  • Agent ergonomics, 83 against 76
  • Payments & pricing, 60 against 32
  • Maintenance & community, 93 against 85
  • Transparency & trust, 81 against 72

Also in its favour

  • Agent-ready, a grade of BB or better
  • No key needed to call it

Watch for

Usage statistics go to Google by default until you pass --no-usage-statistics

Skyvern B

Good for Agents that must finish a multi-step job on sites with logins, 2FA and forms, where stored credentials, saved workflows and cached scripts matter more than raw browser time.

Also in its favour

  • A hosted endpoint, with nothing to install
  • Free to start without a card

Watch for

Every API key and OAuth token has full organisation authority. The docs state there are no read-only, per-endpoint or per-resource keys

Verdicts

Chrome DevTools MCP

Performance traces, network inspection, heap snapshots and Lighthouse audits in one server. Usage statistics go to Google by default until you pass --no-usage-statistics.

Skyvern

The hosted MCP server annotates every tool as read-only or destructive and can advertise a 29 or 32-tool subset in place of 114, and the API has a written six-month deprecation policy. Every key and OAuth token carries full organisation authority, with no read-only or scoped credential, and no request rate limits are documented.

Before you call either

Chrome DevTools MCP

  1. Pass pageId on every page tool. Call list_pages first to get it
  2. Start with --slim for plain browsing, or turn off categories you don't need
  3. Run with --isolated for untrusted sites. The default profile persists between runs
  4. Use filePath on large outputs such as traces and snapshots to keep them out of context
  5. Add --no-usage-statistics if the operator hasn't agreed to Google telemetry

Skyvern

  1. Connect to https://api.skyvern.com/mcp/x/lean or /x/operate, or send X-Skyvern-Scope, so the client loads 32 or 29 tools. The scope filters the list and does not limit permissions
  2. Use a separate Skyvern organisation for each blast radius. Any key or OAuth token can read and write stored credentials and delete workflows
  3. Never pass passwords to skyvern_act or skyvern_type. Store them as credentials and call skyvern_login
  4. Set max_steps on tasks, or x-max-steps-override on agent runs, to cap credits. A run that reaches the cap ends as timed_out
  5. On 503 from POST /v1/run/agents, wait Retry-After seconds. No run was created, so resubmitting is safe
