🔐 Session Management & Authentication

Session Modes

The MCP supports 5 different session management modes:

Configuration Options

🌐 Browserbase (Recommended for Smithery)

Perfect for remote deployments and cloud hosting:

SESSION_MODE=browserbase
BROWSERBASE_API_KEY=bb_live_g3i-b4WPFh__E3cErKE5rO-jWds  # Your API key
BROWSERBASE_PROJECT_ID=d718e85f-be7b-497d-9123-b1bbf798f1bb  # Your project ID
BROWSERBASE_SESSION_ID=                    # Optional: use existing session

🍪 Cookie Authentication (Best for Manual Setup)

Extract cookies from your browser and set them as environment variable:

SESSION_MODE=cookies
GOOGLE_AUTH_COOKIES="session_id=abc123; domain=.google.com; auth_token=xyz789; domain=.google.com"
COOKIES_PATH=~/.jules-mcp/cookies.json     # File to save/load cookies

🌍 Chrome Profile (Local Development)

Use your existing Chrome profile:

SESSION_MODE=chrome-profile
CHROME_USER_DATA_DIR=/Users/yourname/Library/Application Support/Google/Chrome/Default

💾 Persistent Browser Data

Save browser data to a specific directory:

SESSION_MODE=persistent
CHROME_USER_DATA_DIR=~/.jules-mcp/browser-data  # Custom browser data directory

How to Get Google Authentication Cookies

1. Log in to Jules: Visit https://jules.google.com and log in

2. Open Developer Tools: Press F12 or Cmd+Option+I

3. Go to Application/Storage tab

4. Find Cookies: Look for .google.com cookies

5. Copy Important Cookies: Look for cookies like:

   • session_id or sessionid

   • auth_token or authuser

   • SID, HSID, SSID

   • SAPISID, APISID

Format for environment variable:

GOOGLE_AUTH_COOKIES="cookie1=value1; domain=.google.com; cookie2=value2; domain=.google.com"

Environment Configuration

Create a .env file or set environment variables:

# Browser Configuration
HEADLESS=true              # Run browser in headless mode
TIMEOUT=30000              # Browser timeout in milliseconds
DEBUG=false                # Enable debug mode with screenshots

# Session Management
SESSION_MODE=browserbase   # fresh | chrome-profile | cookies | persistent | browserbase

# Browserbase Configuration (for remote/cloud deployments)
BROWSERBASE_API_KEY=your_api_key
BROWSERBASE_PROJECT_ID=your_project_id
BROWSERBASE_SESSION_ID=optional_existing_session

# Cookie Authentication
GOOGLE_AUTH_COOKIES="session_id=abc; domain=.google.com"
COOKIES_PATH=~/.jules-mcp/cookies.json

# Chrome Profile (local development)
CHROME_USER_DATA_DIR=/path/to/chrome/profile

4. Access Remotely: Use your deployed MCP from any Claude Code instance

Benefits of Smithery + Browserbase

• ✅ No Local Browser: Runs entirely in the cloud

• ✅ Persistent Sessions: Maintain Google authentication across deployments

• ✅ Global Access: Use from anywhere with internet connection

• ✅ Auto-scaling: Handles multiple concurrent requests

• ✅ Zero Setup: No local dependencies or configuration needed

Troubleshooting

Common Issues

1. Browser Automation Fails

   • Ensure you have proper access to jules.google.com

   • Check if you're logged into your Google account

   • Try running with HEADLESS=false to see what's happening

2. Task Creation Fails

   • Verify repository names are correct (owner/repo-name format)

   • Ensure you have access to the specified repositories

   • Check that branches exist

3. Permission Errors

   • Make sure you have write access to the data storage path

   • Verify repository permissions in GitHub

Debug Mode

Enable debug mode for troubleshooting:

DEBUG=true HEADLESS=false npm start

This will:

• Show browser interactions visually

• Take screenshots on errors

• Provide detailed logging
