Use My Browser

Control the user's REAL Chrome browser via Tampermonkey injection. Trigger when user says "use my browser", "open in my browser", "check this page for me", or needs to access login-required content. Reuses all login sessions. Does NOT steal the mouse cursor. Requires: openclaw-tmwd plugin + Tampermonkey userscript in Chrome.

Operate the user's real Chrome browser through Tampermonkey script injection. The agent runs JavaScript directly in the page context — sharing all cookies, sessions, and login state.

Setup

bash

openclaw plugins install openclaw-tmwd --registry https://registry.npmjs.org

Then install the Tampermonkey userscript in Chrome. Green indicator at bottom-right = connected.

Tools

Tool	Purpose
tmwd_status	Check connection, list connected tabs
tmwd_switch	Switch to tab matching URL pattern
tmwd_navigate	Navigate current tab to URL
tmwd_newtab	Open new tab
tmwd_text	Get visible text of current page
tmwd_elements	List interactive elements (buttons, links, inputs)
tmwd_scan	Get simplified HTML
tmwd_exec	Execute JavaScript in page context

Workflow

Read a page

text

tmwd_status()                          # Verify connection
tmwd_switch(pattern="github.com")      # Switch to target tab
tmwd_text(max_chars=5000)              # Get page content

Navigate to URL

text

tmwd_navigate(url="https://example.com")
tmwd_text()

Click / fill / interact

text

tmwd_exec(code="document.querySelector('#submit').click()")

tmwd_exec(code="var e=document.querySelector('#email'); e.value='[e-mail]'; e.dispatchEvent(new Event('input',{bubbles:true}))")

Extract data

text

tmwd_exec(code="return document.querySelector('.content').innerText")

tmwd_exec(code="return Array.from(document.querySelectorAll('h2')).map(e=>e.textContent)")

Read table data

text

tmwd_exec(code="var rows=document.querySelectorAll('table tr'); var d=[]; rows.forEach(function(r){var c=[]; r.querySelectorAll('td,th').forEach(function(e){c.push(e.innerText.trim())}); if(c.length) d.push(c)}); return d")

Click by text match

text

tmwd_exec(code="var btns=document.querySelectorAll('button'); for(var i=0;i<btns.length;i++){if(btns[i].innerText.includes('Submit')){btns[i].click();break}}")

Fill form with multiple fields

text

tmwd_exec(code="var f={'#username':'admin','#email':'[e-mail]'}; Object.keys(f).forEach(function(s){var e=document.querySelector(s); e.value=f[s]; e.dispatchEvent(new Event('input',{bubbles:true}))})")

JS Patterns Quick Reference

Action	Code
Click button	document.querySelector('button.submit').click()
Fill input	var e=document.querySelector('#input'); e.value='x'; e.dispatchEvent(new Event('input',{bubbles:true}))
Select dropdown	var s=document.querySelector('select'); s.value='opt1'; s.dispatchEvent(new Event('change',{bubbles:true}))
Check checkbox	var c=document.querySelector('[type=checkbox]'); c.checked=true; c.dispatchEvent(new Event('change',{bubbles:true}))
Scroll to bottom	window.scrollTo(0, document.body.scrollHeight)
Scroll to element	document.querySelector('#target').scrollIntoView()
Wait for element	return !!document.querySelector('.loaded')
Get current URL	return location.href
Go back	history.back()

CSP Fallback

Some sites (X/Twitter, banking sites) block eval() via Content Security Policy. When tmwd_exec returns csp_blocked: true, fall back to the built-in browser tool:

text

1. browser(action="open", profile="openclaw", url="<same-url>")
2. browser(action="snapshot", targetId=<targetId>)

Built-in browser uses CDP which bypasses CSP, but runs in a separate instance (no user login state — login once, profile is persisted).

Rule: always try tmwd first, fall back only on failure.

Troubleshooting

Problem	Fix
"No connected tabs"	Check green indicator in Chrome bottom-right
Red indicator	Refresh the page, userscript auto-reconnects
el.click() no effect	Try el.dispatchEvent(new MouseEvent('click',{bubbles:true}))
CSP blocks eval	Use tmwd_text (no eval needed) or fall back to built-in browser

Notes

• All JS runs in page context — shares cookies, localStorage, login state
• el.click() is DOM-level, does not move the mouse cursor
• Cross-origin iframes cannot be accessed (same-origin policy)
• If page refreshes, the userscript auto-reconnects with the same sessionId
• Use return in JS to send values back; without return there is no output
• For React/Vue apps, always use dispatchEvent after setting values — direct .value= alone won't trigger framework reactivity
