## Setup

### Step 1: Google Cloud Project Setup

1. Go to https://console.cloud.google.com
2. Create a new project (e.g., "Google Drive MCP")
3. Enable these APIs:
   - Google Drive API
   - Google Docs API
   - Google Sheets API
   - Google Slides API
4. Go to OAuth consent screen → configure as External
5. Create OAuth 2.0 credentials:
   - Type: **Desktop app**
   - Download JSON → rename to `gcp-oauth.keys.json`

### Step 2: Configure MCP Client

#### Claude Desktop Configuration
```json
{
  "mcpServers": {
    "google-drive": {
      "command": "npx",
      "args": ["@piotr-agier/google-drive-mcp"],
      "env": {
        "GOOGLE_DRIVE_OAUTH_CREDENTIALS": "/path/to/gcp-oauth.keys.json"
      }
    }
  }
}
```

#### Claude Code Configuration
```bash
claude mcp add-json google-drive '{
  "command": "npx",
  "args": ["@piotr-agier/google-drive-mcp"],
  "env": {
    "GOOGLE_DRIVE_OAUTH_CREDENTIALS": "/path/to/gcp-oauth.keys.json"
  }
}'
```

### Step 3: Authenticate
On first run, a browser window opens for OAuth. Sign in with your Google account and grant permissions. The token is stored securely at `~/.config/google-drive-mcp/tokens.json`.

### Alternative: Official Reference Server

```json
{
  "mcpServers": {
    "gdrive": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-gdrive"],
      "env": {
        "CLIENT_ID": "your-oauth-client-id",
        "CLIENT_SECRET": "your-oauth-client-secret",
        "GDRIVE_CREDS_DIR": "/path/to/credentials"
      }
    }
  }
}
```

## Workflow Patterns

### Pattern 1: Meeting Notes Creator
Use AI to create formatted meeting notes in Google Docs.

```
Prompt: "Create a Google Doc called 'Product Sync - Feb 10, 2026' in the /Meetings folder.
Structure it with:
- Attendees: Alice, Bob, Charlie
- Agenda items
- Discussion notes (I'll dictate)
- Action items with owners
Make the headings bold and properly formatted."
```

Tools flow: `search` (find Meetings folder) → `createGoogleDoc` → `formatGoogleDocParagraph`

### Pattern 2: Spreadsheet Data Entry
Use AI to update project trackers in Google Sheets.

```
Prompt: "Open our 'Sprint Tracker' spreadsheet.
Add a new row for each of these completed tasks:
- Auth redesign (Alice, 5 story points, Done)
- API rate limiting (Bob, 3 story points, Done)
- Dashboard charts (Charlie, 8 story points, In Review)
Calculate the total story points in a sum formula."
```

Tools flow: `search` → `getGoogleSheetContent` → `updateGoogleSheet`

### Pattern 3: File Organization
Use AI to organize files across Drive folders.

```
Prompt: "Search my Drive for all files with 'Q4 2025' in the name.
Create a new folder called 'Q4 2025 Archive' under /Reports.
Move all matching files into that folder."
```

Tools flow: `search` → `createFolder` → `moveItem` (×n)

### Pattern 4: Presentation Builder
Use AI to create slide decks from data.

```
Prompt: "Read the data from our 'Monthly Metrics' spreadsheet.
Create a Google Slides presentation called 'January Performance Review' with:
- Title slide
- Revenue overview (from the spreadsheet data)
- Top 5 products chart data
- Key takeaways
- Next steps"
```

Tools flow: `search` → `getGoogleSheetContent` → `createGoogleSlides`

### Pattern 5: Document Search & Summary
Use AI to find and synthesize information across multiple docs.

```
Prompt: "Search my Drive for documents about 'onboarding process'.
Read the top 3 results and create a new doc called 'Onboarding Summary'
that combines the key steps from all documents into one guide."
```

Tools flow: `search` → `getGoogleDocContent` (×3) → `createGoogleDoc`

### Pattern 6: Report Generation from Sheets
Use AI to generate formatted reports from spreadsheet data.

```
Prompt: "Read our 'Sales Data' spreadsheet for January.
Create a Google Doc report with:
- Executive summary with total revenue
- Top 10 deals table
- Regional breakdown
- Comparison to December
Format it professionally with headings and bold key figures."
```

Tools flow: `getGoogleSheetContent` → `createGoogleDoc` → `formatGoogleDocText`

## Troubleshooting

| Problem | Cause | Solution |
|---------|-------|----------|
| OAuth browser not opening | Running in Docker | Authenticate locally first, then mount tokens |
| "Access denied" | App not verified | Add your email as test user in OAuth consent |
| "API not enabled" | Missing API activation | Enable Drive/Docs/Sheets/Slides APIs in Cloud Console |
| Token expired | 7-day expiry for test apps | Re-authenticate; publish app for longer tokens |
| Can't access shared drives | Missing scope | Add `drive` scope (not just `drive.file`) |
| File not found | Using name instead of ID | Search first to get the file ID, then operate |
| Formatting not applied | Wrong index positions | Use `getGoogleDocContent` to get exact text indices |
| Permission denied to file | OAuth scope limited | Check `drive.file` vs `drive` scope |

## Security Best Practices

1. **Minimum Scopes**: Use `drive.file` scope if you only need access to files the app creates
2. **Token Security**: Tokens stored at `~/.config/google-drive-mcp/tokens.json` with 0600 permissions
3. **Never Commit Credentials**: Add `gcp-oauth.keys.json` and `tokens.json` to `.gitignore`
4. **OAuth App Review**: For production use, submit app for Google verification
5. **Test User Limit**: Testing mode limits to 100 test users
6. **Read-Only Option**: Use `drive.readonly` scope for exploration-only access
7. **Environment Variables**: Store credential paths in env vars, not config files
