aipex-browser

A browser-control skill that lets an agent operate Chrome through an AIPex extension, including navigating pages, clicking, typing, and capturing screenshots.

In plain words
What is it for?
Filling forms, following multi-step web workflows, extracting or downloading page content, managing tabs, and checking accessibility or user experience.
Why use it?
It removes the need to carry out repetitive browser steps by hand during web tasks and browser-based testing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aipex-browser scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AIPex Browser Control

AIPex is a Chrome extension that exposes 30+ browser automation tools over the Model Context Protocol (MCP). Once connected, the agent can control any Chrome tab using natural language — clicking, typing, navigating, capturing screenshots, downloading content, and more.

Architecture:

Agent (MCP client) ──stdio──▶ aipex-mcp-bridge ──WebSocket──▶ AIPex Chrome Extension ──▶ Browser APIs

When to Use This Skill

Use this skill when the user wants to:

  • Navigate to URLs, click links, fill forms, or interact with any web page
  • Automate multi-step browser workflows
  • Extract or download data from web pages
  • Capture screenshots of browser tabs
  • Manage multiple tabs across browser windows
  • Perform browser-assisted testing (accessibility, UX, regression)

Prerequisites

  • AIPex Chrome extension installed (available on the Chrome Web Store or via developer build)
  • Node.js >= 18 installed on the local machine

The user is assumed to have AIPex installed. The agent only needs to complete the two connection steps below.


Step 1: Register the MCP Server

Add the following to the agent's MCP configuration. No manual installation is needed — npx downloads and runs aipex-mcp-bridge automatically.

Cursor (.cursor/mcp.json)

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Claude Code (CLI)

claude mcp add aipex-browser -- npx -y aipex-mcp-bridge

VS Code Copilot (.vscode/mcp.json)

{
  "servers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Windsurf (mcp_config.json)

{
  "mcpServers": {
    "aipex-browser": {
      "command": "npx",
      "args": ["-y", "aipex-mcp-bridge"]
    }
  }
}

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
