# Gemini Cookie Sync Extension Chrome extension that automatically syncs Gemini cookies to the MCP server. ## Installation 1. Open Chrome and go to `chrome://extensions/` 2. Enable **Developer mode** (toggle in top right) 3. Click **Load unpacked** 4. Select this `chrome-extension` folder 5. Login to [gemini.google.com](https://gemini.google.com) ## How it works ``` ┌─────────────────┐ ┌─────────────────┐ ┌─────────────────┐ │ Chrome │ │ Extension │ │ MCP Server │ │ (Gemini) │────▶│ (port 52525) │────▶│ (gemini-chat) │ │ │ │ │ │ │ │ Has cookies │ │ Serves cookies │ │ Fetches cookies│ └─────────────────┘ └─────────────────┘ └─────────────────┘ ``` 1. Extension monitors cookies from `gemini.google.com` 2. Runs a local HTTP server on `http://127.0.0.1:52525` 3. MCP server fetches cookies via `GET /cookies` 4. Cookies auto-refresh when they change ## Usage After installing: 1. Click the extension icon to see current cookie status 2. Green = cookies available 3. Red = need to login to Gemini ## API The extension exposes a simple HTTP endpoint: ``` GET http://127.0.0.1:52525/cookies ``` Response: ```json { "success": true, "cookies": { "__Secure-1PSID": "g.a...", "__Secure-1PSIDTS": "sidts-..." } } ``` ## Troubleshooting **Extension not loading cookies:** - Make sure you're logged into gemini.google.com - Try refreshing the Gemini page - Check Chrome DevTools console for errors **Port 52525 in use:** - Another instance may be running - Check Task Manager for orphan Chrome processes
