Send Jenny a status without leaving your work

Jenny wants to know where the launch is before her 3pm. The answer is in your commits and your checklist. So you ask Claude Code.

Jenny wants a status before her 3pm. Write a short update on the launch and send it to her on WhatsApp with Daiku.
  1. 1Claude Code reads your latest work and writes a short update.
  2. 2It opens WhatsApp in your Daiku browser, finds Jenny and types the update.
  3. 3Daiku asks you before it sends.
  4. 4You read it and approve with Face ID. Jenny has it a moment later.

Daiku wants to send a message on web.whatsapp.com.

Claude Code asked for this.

Approve?

What goes out

Hi Jenny, quick launch status: Checkout and payments are live in staging. iOS build is in App Store review. 2 small bugs left, both in progress. On track for Thursday.

Approvals are a safety net, not a guarantee. Check the details before you approve.

What you see on your phone before it sends.

Add Daiku to the tool you use

Each one signs in the same way: a Daiku window opens in your browser, and you allow it with your passkey.

Claude Code

Run this in your terminal.

claude mcp add --transport http daiku https://daiku.ai/mcp

Then type this in Claude Code, pick Daiku and sign in.

/mcp

Codex

Run this in your terminal.

codex mcp add daiku --url https://daiku.ai/mcp

Then sign in.

codex mcp login daiku

Cursor

Add this to ~/.cursor/mcp.json.

{
  "mcpServers": {
    "daiku": {
      "url": "https://daiku.ai/mcp"
    }
  }
}

Save it, then connect Daiku in Cursor's settings and sign in.

Gemini CLI

Run this in your terminal.

gemini mcp add --transport http daiku https://daiku.ai/mcp

Then type this in Gemini CLI to sign in.

/mcp auth daiku

Close your laptop, and your logins stay

Your Daiku browser runs in the cloud, not on your laptop. It sleeps when no one needs it and wakes, still logged in, the next time an AI does. Pick up later in Claude Code, or ask Claude on your phone.

You still approve on your phone

When Claude Code wants to send, post, pay, buy or delete, your phone lights up. You approve with Face ID or Touch ID. Claude Code can make Daiku stricter, but never looser.

What Claude Code can do in your browser

  • Read docs behind a login

    Your team's wiki, a partner's portal, a paid course.

  • Check a dashboard

    Sign-ups, sales or errors, read straight from the page.

  • Click through your staging site

    Behind your company sign-in, the way a person would.

  • Download reports and files

    Exports, invoices and statements, ready to read.

Log in once, and stay logged in

The first time Claude Code needs a site, it gives you a link to your browser. Log in the way you always do, then tap Hand back. Daiku keeps you logged in.

  • Your passwords never go through Claude Code.
  • Saved a password or a code in your vault? Daiku types it into that site, and only that site, without handing it to Claude Code.
  • Sites see you log in from a country you pick, so nothing looks new to them.
  • bahn.deSigned in
  • amazon.deSigned in
  • lufthansa.comSigned in
  • web.whatsapp.comSigned in
Your sites stay logged in, in your own browser.

For developers

Daiku is a remote MCP server. Add it by this address in any app that can add one.

Daiku's address
https://daiku.ai/mcp
  • Your app signs in through a Daiku window, with your passkey. You allow each app once.
  • Each person gets their own Chrome in the cloud, shared only with their AI apps. Several apps can use it at once, each in its own tabs.
  • Text from pages comes back marked as page content, not as instructions.
  • Sends, payments and deletes wait for your passkey. Your app can't approve for itself.
  • Every action lands in your log, with the app that asked for it.

Another app? If it can add a remote MCP server by its address, paste Daiku's link and sign in when it asks.

Questions

Is this for testing my own app?

Not really. Tools that drive a browser on your own computer are great for testing your app as you build it. Daiku is for your real sites, logged in as you, with your yes before anything is sent or paid.

Does it use my own Chrome?

No. Claude Code gets a Chrome of its own, in the cloud. Nothing runs on your computer, and your own browser stays yours.

Does my laptop need to stay on?

Not for your logins. Your Daiku browser sleeps when no one needs it and wakes when an AI does, still logged in. Claude on your phone can use it while your laptop is shut.

Does Claude Code see my passwords?

No. Claude Code gives you a link to your browser, you log in yourself, and you hand it back. Passwords and codes in your vault are typed into the site without being handed to Claude Code.

Does it work with Codex, Cursor and Gemini CLI?

Yes. Add the same link to each, as shown above. They share one browser and your logins, and your log shows which one did what.

What if Daiku is already in Claude?

Claude Code can use the Daiku you added in Claude. Adding it with the command too gets Claude Code the newest Daiku each time it starts. If Daiku shows up twice, turn one of them off.
