+# Google Drive Integration
+
+Connect your Google Drive to agentic sessions so Claude can read and write files in your Drive.
+
+## What It Does
+
+Once connected, Claude can:
+- List files and folders in your Google Drive
+- Read file contents
+- Create new files
+- Update existing files
+- Search your Drive
+
+## How to Use
+
+### 1. Connect Google Drive to a Session
+
+1. Open or create an agentic session
+2. In the left sidebar, expand **"MCP Integrations"**
+3. Click **"Connect"** on the Google Drive card
+4. Authorize in the popup window
+5. Close the popup when you see "Authorization Successful"
+
+### 2. Use Drive in Your Prompts
+
+Once connected, you can ask Claude things like:
+
+- "List the files in my Google Drive"
+- "Read the contents of 'meeting-notes.txt' from my Drive"
+- "Create a new document in my Drive called 'project-summary.md' with this content..."
+- "Find all PDFs in my Drive from last month"
+
+### 3. Disconnect (Optional)
+
+Credentials are automatically removed when the session ends. To disconnect earlier, click "Disconnect" in the MCP Integrations accordion.
+
+## First-Time Setup (Admin)
+
+Administrators need to configure Google OAuth credentials once:
+
+1. Create a Google Cloud project and OAuth 2.0 credentials
+2. Set authorized redirect URI to: `https://your-vteam-backend/oauth2callback`
+3. Create a Kubernetes Secret in the operator namespace:
+
+```bash
+kubectl create secret generic google-workflow-app-secret \
+  --from-literal=GOOGLE_OAUTH_CLIENT_ID='your-client-id' \
+  --from-literal=GOOGLE_OAUTH_CLIENT_SECRET='your-client-secret'
+```
+
+## Security & Privacy
+
+- **Session-scoped**: Credentials only exist for the current session
+- **Automatic cleanup**: Credentials deleted when session ends
+- **No sharing**: Your credentials never accessible to other users or sessions
+- **You control access**: You must explicitly connect for each session
+
+## Troubleshooting
+
+**"Connect" button doesn't work**
+- Check that popup blockers aren't blocking the OAuth window
+
+**Claude says it can't access Drive**
+- Verify you see "Connected" status in MCP Integrations accordion
+- Try disconnecting and reconnecting
+- Check the session logs for errors
+
+**"Invalid scopes" error**
+- You may need to re-authorize with updated permissions
+- Click "Disconnect" then "Connect" again
