Credits : Based on Mario Zechner's article What if you don't need MCP?, adapted from Factory.ai.
Setup
Before first use, install dependencies:
npm install --prefix skills/browser
Start Chrome
./skills/browser/scripts/start.js # Fresh profile
./skills/browser/scripts/start.js --profile # Copy your profile (cookies, logins)
Start Chrome on :9222 with remote debugging.
Navigate
./skills/browser/scripts/nav.js https://example.com
./skills/browser/scripts/nav.js https://example.com --new
Navigate current tab or open new tab.
Evaluate JavaScript
./skills/browser/scripts/eval.js 'document.title'
./skills/browser/scripts/eval.js 'document.querySelectorAll("a").length'
Execute JavaScript in active tab (async context).
IMPORTANT : The code must be a single expression or use IIFE for multiple statements:
- Single expression:
'document.title'
- Multiple statements:
'(() => { const x = 1; return x + 1; })()'
- Avoid newlines in the code string - keep it on one line
Screenshot
./skills/browser/scripts/screenshot.js
Screenshot current viewport, returns temp file path.
Pick Elements
./skills/browser/scripts/pick.js "Click the submit button"
Interactive element picker. Click to select, Cmd/Ctrl+Click for multi-select, Enter to finish.
Workflow
- Start Chrome with
start.js --profile to mirror your authenticated state.
- Drive navigation via
nav.js https://target.app or open secondary tabs with --new.
- Inspect the DOM using
eval.js for quick counts, attribute checks, or extracting JSON payloads.
- Capture artifacts with
screenshot.js for visual proof or pick.js when you need precise selectors or text snapshots.
Usage Notes
- Start Chrome first before using other tools
- The
--profile flag syncs your actual Chrome profile so you're logged in everywhere
- JavaScript evaluation runs in an async context in the page
- Pick tool allows you to visually select DOM elements by clicking on them
