Secure Local MCP Server for Sharing Chrome Sessions with AI Agents

Secure Local MCP Server for Sharing Chrome Sessions with AI Agents

Overview

browser-context-gateway is an open-source project designed to run a local MCP (Multi-Context Proxy) server on your desktop (e.g., Windows). It securely accesses your active Chrome web sessions — with explicit user approval — and exposes them to browser AI agents running locally or within your private network.

This approach enables AI agents to execute tasks using your actual browser context (cookies, sessions, tabs) without exposing your credentials remotely or granting full account control. It’s a privacy-first, secure alternative to directly sharing your user/pass or remote controlling agents that handle sensitive browsing data.

Why browser-context-gateway?

  • User-Centric Security: Your Chrome session data never leaves your device without your consent.
  • No Credential Sharing: Agents interact through your browser context, so you never share passwords or tokens.
  • Local Control: The MCP server runs locally on your machine, reducing attack surface and dependency on cloud services.
  • Extensible: Designed to serve multiple AI agents in your "beehive" ecosystem — empowering automation while respecting privacy.

How It Works

  1. You start the browser-context-gateway MCP server on your desktop.
  2. It detects and accesses your active Chrome web session data with your explicit approval.
  3. The server exposes an API/interface that AI agents can connect to and execute browser tasks on your behalf.
  4. AI agents perform actions (e.g., web scraping, form submission, navigation) securely within your authorized Chrome context.
  5. You retain full control — sessions are shared only with approved agents and can be revoked anytime.
