## Executive Summary
This MCP server provides comprehensive Google Sheets integration for the AgenticLedger platform. All tools have been tested with real Google Sheets API calls and are production-ready. The server uses TypeScript for type safety, Service Account authentication for security, and follows AgenticLedger's standardized response format.
### Key Features

- ✅ Batch operations for efficiency
- ✅ Chart creation and management
- ✅ Row/column insertion and deletion
- ✅ Metadata retrieval and sheet management
- ✅ Type-safe with Zod schema validation
- ✅ All parameters documented with `.describe()`
---
## Authentication Configuration
### Service Account Setup
**Required Files:**
- `service-account-key.json` - Downloaded from Google Cloud Console
- `.env` file with environment variables
**Environment Variables:**
```bash
GOOGLE_PROJECT_ID=your-project-id
GOOGLE_APPLICATION_CREDENTIALS=/absolute/path/to/service-account-key.json
```
**Alternative (JSON String):**
```bash
GOOGLE_SERVICE_ACCOUNT_KEY='{"type":"service_account","project_id":"...",...}'
```
### Access Token Parameter
All tools accept an `accessToken` parameter for AgenticLedger platform integration:
```typescript
{
accessToken: z.string().optional().describe('OAuth access token for authentication'),
// ... other parameters
}
```
**Note:** The server primarily uses Service Account authentication. The `accessToken` parameter is available for platform-level token management but is optional when using service account credentials.

### API Quotas
**Google Sheets API Limits:**
- Read requests: 100 per 100 seconds per user
- Write requests: 100 per 100 seconds per user
- Per-minute quota: 60,000 requests
**Recommendation:** Use batch operations for bulk updates to stay within limits.

## AgenticLedger Platform Integration
### MCP Configuration
Add to AgenticLedger MCP config:
```json
{
"mcpServers": {
"google-sheets": {
"command": "node",
"args": [
"/absolute/path/to/GoogleSheetsMCP/dist/index.js"
],
"env": {
"GOOGLE_PROJECT_ID": "your-project-id",
"GOOGLE_APPLICATION_CREDENTIALS": "/path/to/service-account-key.json"
}
}
}
}
```
### Token Management
The server supports both authentication methods:
1. **Service Account** (recommended): Persistent authentication via JSON key
2. **Access Token**: Platform-managed tokens via `accessToken` parameter
### Type Safety
All tools use Zod schemas with `.describe()` for parameter validation:
```typescript
const GetValuesSchema = z.object({
spreadsheetId: z.string().describe('The ID of the Google Sheets document'),
range: z.string().describe('A1 notation range (e.g., "Sheet1!A1:C10")'),
accessToken: z.string().optional().describe('OAuth access token')
});
```
This ensures AI agents receive clear parameter descriptions and type information.

## Security Considerations
### Credential Management
1. **Never commit credentials** to version control
2. **Use environment variables** for sensitive data
3. **Rotate service account keys** every 90 days
4. **Limit service account permissions** to minimum required
### Access Control
1. **Share spreadsheets explicitly** with service account email
2. **Use separate service accounts** for dev/staging/prod
3. **Monitor API usage** in Google Cloud Console
4. **Set up alerts** for unusual activity
### Rate Limiting
The server implements exponential backoff for API rate limit errors:
```typescript
// Automatic retry with backoff on 429 errors
if (error.code === 429) {
await sleep(Math.pow(2, retryCount) * 1000);
// Retry request
}
```

## Troubleshooting Guide
### Common Issues
#### 1. "Permission denied" errors
**Cause:** Service account not shared with spreadsheet
**Solution:** Share spreadsheet with service account email (`client_email` from JSON key)
#### 2. "Spreadsheet not found"
**Cause:** Invalid spreadsheet ID or no access
**Solution:** Verify ID from URL: `https://docs.google.com/spreadsheets/d/[ID]/edit`
#### 3. "Authentication failed"
**Cause:** Invalid credentials or API not enabled
**Solution:**
- Verify JSON key file path
- Enable Google Sheets API in Cloud Console
- Check `GOOGLE_PROJECT_ID` matches
#### 4. "Quota exceeded"
**Cause:** API rate limit reached
**Solution:**
- Use batch operations
- Implement exponential backoff
- Increase quotas in Cloud Console (if needed)
#### 5. Slow performance
**Cause:** Multiple sequential requests
**Solution:** Use batch operations:
- `sheets_batch_get_values` instead of multiple `sheets_get_values`
- `sheets_batch_update_values` instead of multiple `sheets_update_values`
---
## Best Practices
### 1. Use Batch Operations
```typescript
// ❌ Slow: 3 separate requests
await sheets_get_values({ range: "A1:A10" });
await sheets_get_values({ range: "B1:B10" });
await sheets_get_values({ range: "C1:C10" });
// ✅ Fast: 1 batch request
await sheets_batch_get_values({
ranges: ["A1:A10", "B1:B10", "C1:C10"]
});
```
### 2. Specify Exact Ranges
```typescript
// ❌ Inefficient: Reads entire column
range: "A:A"
// ✅ Efficient: Reads only needed rows
range: "A1:A100"
```
### 3. Use Appropriate Value Input Options
```typescript
// For formulas and smart parsing
valueInputOption: "USER_ENTERED"
// For raw string values
valueInputOption: "RAW"
```
### 4. Handle Empty Data
```typescript
// Always check for empty results
const { data } = await sheets_get_values({ range });
if (!data.values || data.values.length === 0) {
// Handle empty case
}
```
### 5. Implement Error Handling
```typescript
try {
const result = await sheets_update_values(params);
if (!result.success) {
console.error('Update failed:', result.error);
}
} catch (error) {
// Handle network errors, etc.
}
```
