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.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00067 | $0.01353 |
| Opus 5 | $0.00034 | $0.00677 |
| Sonnet 5 | $0.00013 | $0.00271 |
| Haiku 4.5 | $0.00007 | $0.00135 |
Grade A, and why
chrome-devtools-mcp 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.
🌐 Chrome DevTools MCP
Google's official Chrome DevTools MCP server — gives AI agents full control of a live Chrome browser via Puppeteer and the Chrome DevTools Protocol.
Features
- Input automation — click, drag, fill forms, hover, press keys, upload files, handle dialogs
- Navigation — open/close/switch pages, wait for elements/network idle
- Screenshots & snapshots — capture page state visually and as DOM
- Performance traces — record and analyze Chrome performance traces with insights
- Network inspection — list/inspect network requests and responses
- Console debugging — read console messages with source-mapped stack traces
- Device emulation — emulate mobile devices, resize viewport
- Form automation — fill multiple form fields at once
Requirements
- Node.js v20.19+ (already available in OpenClaw)
- Chrome/Chromium browser
Quick Start
Install & verify
npx -y chrome-devtools-mcp@latest --help
Start the MCP server
# Standard (launches Chrome automatically)
npx -y chrome-devtools-mcp@latest
# Headless mode (for servers)
npx -y chrome-devtools-mcp@latest --headless
# Connect to existing Chrome (must be started with --remote-debugging-port=9222)
npx -y chrome-devtools-mcp@latest --browser-url=http://127.0.0.1:9222
# Disable telemetry
npx -y chrome-devtools-mcp@latest --no-usage-statistics --no-performance-crux
OpenClaw MCP Integration
Add to your openclaw.json under MCP servers:
{
"mcp": {
"servers": {
"chrome-devtools": {
"command": "npx",
"args": ["-y", "chrome-devtools-mcp@latest", "--headless", "--no-usage-statistics"]
}
}
}
}
Or use the setup script:
python3 {baseDir}/scripts/setup_chrome_mcp.py setup
python3 {baseDir}/scripts/setup_chrome_mcp.py status
python3 {baseDir}/scripts/setup_chrome_mcp.py test

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

chrome-devtools-mcp is a skill published in the GitHub repository leecyno1/boutique-skills (5 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 1,353 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
