chrome-devtools

chrome-devtools is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from CesiumGS/cesiumjs-skills. Its token cost is not measured, scanned A, original, Apache-2.0.

A connection that lets an agent inspect and control a live Chrome browser through Chrome DevTools. Chrome DevTools is the browser's built-in toolkit for checking pages, errors, requests, and performance.

In plain words
What is it for?
Use it to inspect performance traces, network activity, and console messages, or automate a locally running Chrome instance.
Why use it?
It lets the agent investigate what is happening in a running browser instead of relying only on source code or static files.

Security

Grade A, and why

chrome-devtools scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
