chrome-devtools

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

A connection that lets an agent use Chrome DevTools, the browser’s built-in tools for inspecting and debugging web pages. It starts a local server named chrome-devtools.

In plain words
What is it for?
Connecting an agent to Chrome DevTools for web-page inspection and debugging.
Why use it?
It gives the agent access to browser inspection and debugging through a standard connection instead of requiring those tools to be built into the agent.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 3d 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 — 0 lines 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.

This page is one entry in a file that holds 7. Installing the file brings all of them; each is measured and scanned on its own page.

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.
