Vibe Browser MCP lets AI agents control your real logged-in Chrome session via an open-source package, with 25+ tools and multi-agent relay support.

AI Summary

  • •Vibe Browser MCP exposes your existing Chrome browser—with all logged-in sessions, extensions, and cookies intact—directly to AI agents as an MCP (Model Context Protocol) server, with no separate browser instance or debug port required.
  • •The package includes 25+ tools across navigation, interaction, Google Workspace integration (Gmail and Calendar), credential management, and sub-agent orchestration; agents can run locally on your machine or connect remotely via a public relay server (relay.vibebrowser.app) using UUID authentication.
  • •The npm package (@vibebrowser/mcp) is open source; the browser extension is not. Set-up takes under 2 minutes and works with Vibe AI, Anthropic Claude Max, GitHub Copilot, and bring-your-own-key providers.
