How to let an agent use your own logged-in browser with Bladebro

Point the agent at your real Chromium-family browser with your profile and logins.

Authorization notice. Bladebro is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Credentials. The agent acts inside your logged-in profile and can reach your accounts, so confirm each sensitive action before it runs.

Who it is forA user who needs an agent to act inside a site they are already logged into in their own browser.

The problemA fresh automated browser has no logins, so the agent cannot reach pages that need your account.

The outcomeThe agent works in your own browser profile, with your logins and display, and reports each action it takes.

What you need first

  • Node.js 14 or newer for the npm install
  • Chrome or Chromium installed on the machine
  • An MCP-capable AI agent or client to connect to the bladebro mcp server

Steps

  1. Run npm install -g bladebro.
  2. Run bladebro rb on to switch the browser surfaces to your own Chromium-family browser.
  3. Run bladebro mcp and connect the server to your AI agent.
  4. Ask the agent to open the target site and perform the task, then confirm the result on screen.

Prompt for your agent

Use the bladebro MCP server in real-browser mode to open <site URL> and complete <task>. Return a summary of each action and the final page state. Verify that the account shown is the one you intended before any change is saved.

Caveat. Real-browser mode turns off the page-injection layer, so it relies on your own real environment rather than the stealth patches.
