@proxies-sx/browser-mcp

MCP server for browser.proxies.sx — AI-native antidetect browser with Identity Bundles and auto-allocated mobile proxy.

What It Does

Control a cloud antidetect browser (Camoufox) through the Model Context Protocol. Every session includes a real 4G/5G mobile proxy — no setup, no accounts, just pay with USDC.

11 tools for complete browser automation:

Identity Bundles (v1.1.0)

Save and restore complete browser identity across sessions:

• Cookies — All session cookies, encrypted at rest
• localStorage — App state, tokens, preferences
• Fingerprint — OS, screen resolution, locale, timezone
• Proxy device binding — Same physical modem (IMEI pinning) for consistent IP range

Day 1: Create session → Login to Twitter → browser_save → get profile_id
Day 30: browser_create with profile_id → Same fingerprint, same proxy device, cookies restored

Profiles persist until deleted. Auto-cleanup after 30 days of inactivity.
