Agent Browser MCP Server

See what your agent sees. Self-hosted Chrome for AI agents. Your agent drives one real browser session - and you can watch it happen, and step in. It runs locally over stdio via the published package.

People who work with browser automation, chrome and computer use and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Agent Browser

before you install - you'll need

SESSION_ID

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add aetherai3-agent-browser -- npx -y aether-browser

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "aetherai3-agent-browser": {
      "command": "npx",
      "args": [
        "-y",
        "aether-browser"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
