This MCP server gives AI direct access to your Toast POS system. Stop manually pulling reports, updating menu items, or tracking labor costs. Just tell Claude what you need, and it happens.

🎯 Toast-Specific Power Moves

Use Case	What It Does	Tools Used
"86" items instantly	Mark menu items out of stock across all terminals	`list_menu_items`, `update_menu_item`
Daily sales reconciliation	Pull all orders + payments for a business day	`list_orders`, `get_order`, `list_checks`
Labor cost analysis	Compare actual hours worked vs. scheduled shifts	`list_employees`, `get_labor`
Order investigation	Find specific orders by time/amount, void if needed	`list_orders`, `get_order`, `void_check`
Menu sync verification	Audit menu items against your master menu list	`list_menu_items`

🔗 The Real Power: Natural Language Restaurant Ops

Instead of clicking through Toast dashboards:

"Show me all orders from last night's dinner rush (5-9pm)"
"Mark the grilled salmon as 86'd"
"What's our total labor cost for this week?"
"Find the order with the $127 total from yesterday"
"Void check #4521 — customer never showed up"

📦 What's Inside

8 restaurant-focused API tools covering Toast's core POS functionality:

Orders: list_orders, get_order — Sales data, items, modifiers, payments
Checks: list_checks, void_check — Tab management and corrections
Menu: list_menu_items, update_menu_item — Inventory & 86'd items
Labor: list_employees, get_labor — Staff scheduling & time tracking

All with automatic OAuth2 authentication, proper error handling, and TypeScript types.

🚀 Quick Start

Option 1: Claude Desktop (Recommended)

Clone and build:

git clone https://github.com/BusyBee3333/Toast-MCP-2026-Complete.git
cd toast-mcp-2026-complete
npm install
npm run build

Get your Toast API credentials:
- Log into Toast Developer Portal
- Create a new integration (Restaurant Management API)
- Save your Client ID, Client Secret, and Restaurant GUID

Configure Claude Desktop:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "toast": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/toast-mcp-2026-complete/dist/index.js"],
      "env": {
        "TOAST_CLIENT_ID": "your-client-id",
        "TOAST_CLIENT_SECRET": "your-client-secret",
        "TOAST_RESTAURANT_GUID": "your-restaurant-guid"
      }
    }
  }
}

Restart Claude Desktop — you'll see 8 Toast tools appear in the MCP section

Option 2: Local Development

cp .env.example .env
# Edit .env with your Toast credentials
npm run dev

🔐 Authentication

Toast uses OAuth2 Client Credentials flow:

Go to Toast Developer Portal
Navigate to Integrations → Create Integration
Select Restaurant Management API scope
Copy your Client ID and Client Secret
Find your Restaurant GUID in Toast Web (Settings → Restaurant Info)

Required Scopes:

Orders (read)
Menus (read/write)
Labor (read)

API Docs: https://doc.toasttab.com/doc/devguide/apiOverview.html

The MCP server automatically handles token refresh (tokens expire after 1 hour).

🐛 Troubleshooting

"Toast auth error: 401"

Verify your Client ID and Client Secret are correct
Check that your integration has the required scopes enabled
Ensure your Restaurant GUID matches your actual restaurant

"Toast API error: 403 Forbidden"

Your API credentials don't have the necessary permissions
Check your integration's scope settings in the Toast Developer Portal

"Tools not appearing in Claude"

Restart Claude Desktop after updating claude_desktop_config.json
Verify the path is absolute (no ~ or relative paths)
Check that npm run build completed successfully
Look for the dist/index.js file

"Toast-Restaurant-External-ID header required"

Make sure TOAST_RESTAURANT_GUID is set in your environment
This is different from your Client ID — find it in Toast Web settings
