Your agent gets stuck on a login. It hands you the tab.
Claude Code, Codex or any agent driving a Chromium browser: when it hits a password, 2FA code, captcha or approval, it calls ask_human and sends you a one-time link. You see its browser tab, finish the step from your phone, and it carries on.

Why not a cloud browser
Works where your agent runs
Your Mac, a server, Docker or a CI box: the agent shares its own browser tab. No cloud browser, no profile migration.
End-to-end encrypted
Frames and your keystrokes are encrypted with a key that lives only in the link. Our servers relay bytes they cannot read.
The session stays with the agent
You log in once in the agent's browser; cookies stay there. The agent continues in the same tab and never sees your password.
How it works
Create an agent token in the dashboard and add the ShowMyTab MCP server to your agent with one command.
When the agent is blocked it calls ask_human. You get a message with a one-time link, valid 10 minutes, that opens only for members of your account.
You see the tab on your phone: watch, take control, finish the step, press Done. The agent's wait_for_human returns and it continues.
Install in Claude Code
claude mcp add showmytab -e SHOWMYTAB_TOKEN=smt_agent_… -e SHOWMYTAB_CDP=http://127.0.0.1:9222 -- npx -y https://showmytab.com/agent/showmytab-agent.tgz mcp
{
"mcpServers": {
"showmytab": {
"command": "npx",
"args": [
"-y",
"https://showmytab.com/agent/showmytab-agent.tgz",
"mcp"
],
"env": {
"SHOWMYTAB_TOKEN": "smt_agent_…",
"SHOWMYTAB_CDP": "http://127.0.0.1:9222"
}
}
}
}Works with any MCP client (Codex, Cursor, custom agents). The CLI has ask and watch commands too.
Instruction for your agent
If a website asks for a password, 2FA code, captcha or an approval, never ask me to type it in chat. Call the ShowMyTab ask_human tool, send me the message it returns, then call wait_for_human and continue.
Frequently asked questions
Which agents are supported?
Any agent that drives a Chromium browser through the DevTools protocol: Claude Code, Codex, Playwright, Puppeteer or Browser Use scripts. The MCP server exposes ask_human and wait_for_human; the CLI covers the rest.
Can the agent see my password?
No. You type into a live view; keystrokes travel encrypted to the agent's browser and land in the page. The agent only learns that the step is done.
Who can open the link?
Only signed-in members of the account that owns the agent token, and only the first person who opens it. Links expire after 10 minutes; a handoff lasts at most 30 minutes.
Can I just watch what the agent is doing?
Yes. The dashboard shows which agents are online and lets you watch their tabs live, view-only. The agent can also open a watch-only link with control: false.
What does it cost?
Agent handoff is in closed beta. Ask for access at [email protected]; pricing is announced with general availability.
