Tools Available

1. get_keys - Get column headers from sheet
2. smart_add_data - Intelligently add data (import_json for empty sheets, create for existing)
3. read_sheet - Read data from sheet
4. import_json - Import JSON data to empty sheets

Usage Examples

Adding Meal Data

User: "Add chicken dinner (340 calories, 25g protein) to my calorie tracker: https://sheetdb.io/api/v1/your-id"

Claude will:
1. Call get_keys to check headers
2. Call smart_add_data with proper mapping
3. Either create headers (first time) or add to existing sheet

Reading Data

User: "Show me my last 5 meals"
Claude: [Uses read_sheet with limit=5]

Updating Entries

User: "Update yesterday's breakfast calories to 350"
Claude: [Uses update_row to find and modify the entry]

Configuration

The server expects SheetsDB endpoints in this format:

https://sheetdb.io/api/v1/YOUR_SHEET_ID

No additional configuration required - just provide the endpoint when using tools.

Security Notes

• Endpoints are validated to ensure they're legitimate SheetsDB URLs
• No API keys stored in the server (SheetsDB handles auth via URL)
• All requests go directly to SheetsDB's secure endpoints
