Kash — POS, Invoicing, CRM & Webshop

# Kash MCP Server — Official Integration > **Connect your Kash business to Claude, ChatGPT, and any MCP-compatible AI — and run your entire operation through natural conversation.** Kash has been a free, cloud-based point-of-sale solution since 2011, trusted by thousands of merchants across restaurants, retail, bakeries, florists, food trucks, and more. This MCP server is the official bridge between Kash and the new generation of AI assistants, turning every tool in your business into something you can simply talk to. --- ## What is Kash? Kash (kash.click) is a complete, free business management platform built for small and medium businesses. It goes far beyond a simple cash register: - **Point of Sale** — touchscreen-ready, works on any device (Android, iOS, Windows, Mac), online and offline - **Invoicing & Quotes** — generate PDF invoices, quotes, delivery notes, and expense reports in seconds - **CRM** — manage your full customer base with contact details, purchase history, loyalty points, credits, and custom fields - **Online Store / Webshop** — built-in e-commerce storefront synced with your catalog and inventory - **Inventory Management** — real-time stock tracking, alerts, supplier management, and buying prices - **Delivery Management** — table service, takeaway, drive-through, home delivery, relay points, and shipping - **Loyalty & Marketing** — loyalty cards, loyalty points, coupons, vouchers, referral programs, and marketing campaigns - **Payment Flexibility** — cash, card (SumUp, Yavin, Viva.com), PayPal, Lydia, GoCardless, direct debit, and even cryptocurrency - **Reporting & Analytics** — sales reports, revenue charts, export to CSV, accounting chapter mapping, and Pennylane integration - **Multi-user & Multi-cashbox** — manage staff access, roles, and multiple physical or virtual cashboxes All of this is **free** for small businesses, with no mandatory subscription. --- ## What Does This MCP Server Do? This server exposes the full Kash API as **35 MCP tools**, letting any compatible AI assistant — Claude, ChatGPT, n8n, or your own automation — interact with your Kash account through natural language. No more clicking through menus. Just talk. --- ## What You Can Do ### 🔐 Account & Authentication Get started without leaving the conversation. You can create a Kash account, find existing accounts linked to your email, and authenticate via a secure one-time password (OTP) sent to your inbox — all from within the chat. ``` "Create a Kash account for my restaurant" "Log me in with my email" "I received the OTP code: 847291" ``` ### 🧾 Sales & Orders Record sales in real time, attach them to tables or customers, apply payment methods, add comments, and handle delivery modes — all from a single sentence. ``` "Record a sale of 2 espressos and a croissant at table 5, paid by card" "Show me today's sales" "What orders are pending for delivery tonight?" "Give me the detail of order #1042" ``` ### 📦 Catalog Management Add, update, or remove items, departments, and VAT rates on the fly. Adjust prices, link variations, set stock levels, toggle visibility — without opening the back office. ``` "Add a new item called 'Seasonal Tart' at €4.50 in the Pastries department" "Update the price of the Margherita pizza to €12" "Create a new department called 'Summer Menu'" "Add a 10% VAT rate" ``` ### 👥 Customer Management (CRM) Maintain a full customer database. Add new customers, update contact details, manage addresses, company registration numbers, VAT numbers, blacklist status, and private notes. ``` "Add a new customer: John Smith, john@example.com, +33612345678" "Update the address for customer #204" "Show me all my customers" ``` ### 📊 Data & Reporting Retrieve any data from your shop instantly — products, departments, VAT rates, users, cashboxes, payment methods, delivery zones, discounts, tables, relay points, and more. ``` "List all my products" "What payment methods are configured?" "Show me this week's orders" "How many tables do I have?" ``` --- ## Example Conversations Here are real things you can ask once connected: > *"Show me today's sales"* > *"Record a sale of 2 coffees and 1 croissant at table 84"* > *"How is the business doing so far this year?"* > *"Can you analyse my sales history and give me recommendations?"* > *"Add a new seasonal item to my menu at €8.50"* > *"Which customers haven't ordered in the last 3 months?"* > *"Generate a cash register report for the week"* > *"How many orders have to be delivered tonight?"* > *"I need to add a new VAT rate of 5.5% for food items"* --- ## Available Tools (35) | Category | Tools | |---|---| | **Account** | `account_list`, `account_create` | | **Authentication** | `auth_request_otp`, `auth_login_with_otp`, `auth_logout` | | **Sales** | `sale_create`, `order_detail`, `data_list_orders` | | **Catalog — Items** | `plu_add`, `plu_edit`, `plu_delete`, `data_list_products` | | **Catalog — Departments** | `dept_add`, `dept_edit`, `dept_delete`, `data_list_departments`, `data_list_department_groups` | | **Catalog — VAT** | `vat_add`, `vat_edit`, `vat_delete`, `data_list_vats` | | **CRM** | `client_add`, `client_edit`, `client_delete`, `data_list_clients` | | **Data** | `data_list_users`, `data_list_tables`, `data_list_cashboxes`, `data_list_payments`, `data_list_discounts`, `data_list_variations`, `data_list_delivery_men`, `data_list_delivery_zones`, `data_list_relay_points` | | **Utility** | `ping` | --- ## Who Is This For? This MCP server is ideal for: - **Restaurant & café owners** who want to record orders, track tables, and analyse revenue through conversation - **Retail shop managers** who need to quickly update prices, add items, or check stock without navigating the back office - **Bakeries, florists, food trucks** and any local business that wants an AI assistant deeply connected to their daily operations - **Developers & agencies** building AI-powered workflows on top of a proven POS platform - **n8n / automation users** who want to trigger Kash actions from workflows --- ## Getting Started ### Option 1 — You already have a Kash account Simply connect via OAuth. The server will ask for your login email and send you a one-time password to verify your identity. Once authenticated, all 35 tools are immediately available. ### Option 2 — You don't have a Kash account yet No problem — just ask the AI to create one for you: > *"Create a Kash account for my bakery, my email is hello@mybakery.com"* The account is created instantly, the session is initialized automatically, and you're ready to go. Don't forget to validate your email via the link sent to your inbox. --- ## Technical Details - **Protocol**: MCP (Model Context Protocol) over HTTP Streamable - **Authentication**: OAuth 2.0 with PKCE (S256) — secure, no password required - **Hosted server**: `https://mcp.kash.click/mcp` - **Self-hosted option**: Available via `npx caisse-enregistreuse-mcp-server` or Docker - **Open source**: [github.com/paracetamol951/caisse-enregistreuse-mcp-server](https://github.com/paracetamol951/caisse-enregistreuse-mcp-server) - **License**: GPL v3 --- ## Links - 🌐 [kash.click](https://kash.click) — Kash website - 📖 [Documentation](https://kash.click/cash-register-software/) — Full help center - 🔧 [API Reference](https://kash.click/cash-register-software/mcp/) — MCP & API docs - 💻 [GitHub](https://github.com/paracetamol951/caisse-enregistreuse-mcp-server) — Source code - 🆓 [Register for free](https://kash.click/free-pos-software/) — Create your account
