AIPex is an open-source browser automation agent that operates inside the browser a user already uses, controlling pages, tabs, and other browser functions locally. It is intended for people who want browser automation without migrating to another browser, with agents connecting through MCP, skills, or its browser command-line interface. The catalogue skills and instructions extend or operate AIPex's local browser runtime.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.01845 |
| Opus 5.5 | $0.00024 | $0.00738 |
| Sonnet 5.5 | $0.00012 | $0.00369 |
| Haiku 4.5 | $0.00006 | $0.00185 |
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 1mo 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.

The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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)

"args": ["-y", "aipex-mcp-bridge"]
}
}

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

aipex-browser is a skill published in the GitHub repository AIPexStudio/AIPex (1,269 stars, last pushed 1mo ago), licensed MIT. It adds 61 tokens to every session and 1,845 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
