chrome-devtools

chrome-devtools is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from thangchung/agent-engineering-experiment. Its token cost is not measured, scanned A, a copy of chrome-devtools, MIT.

A local connection between the coding agent and a running Chrome browser, using Chrome's developer interface. It exposes performance traces, network activity, and console output.

In plain words
What is it for?
Use it to inspect browser performance, review network requests, and read console messages while diagnosing a web application.
Why use it?
It lets the agent inspect what a web page and browser are doing instead of relying only on source code or descriptions. This helps investigate slow pages, failed requests, and browser errors.

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 6d 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.

Origin

This is a copy

100% identical to chrome-devtools — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
