Connects to Lightspeed X-Series retail POS systems. Muse can read products, inventory levels, sales reports, customers and staff; search by date, outlet or payment type; update prices and stock counts; and create or edit customer records.

Example request: "Show me my total sales for this week broken down by payment type and top products."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Lightspeed Retail X-Series to help me. It is a free service with an MCP server at https://lightspeed-x-series.usefulapi.io/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

- lightspeedxseries_get_outlet: One outlet by id. GET /outlets/{outlet_id}.
- lightspeedxseries_list_registers: List registers (tills): id, name, outlet_id, is_open, open/close times and invoice numbering. Paginate with next_after. GET /registers.
- lightspeedxseries_get_register_payments_summary: Payment totals by payment type for one register since it was opened (the end-of-day / cash-up view). GET /registers/{register_id}/payments_summary.

- lightspeedxseries_get_user_sale_totals: Sales totals for one staff user, as the vendor computes them (no date filter; use sales_summary for a period). GET /users/{user_id}/sale_totals.
- lightspeedxseries_list_products: List products (variants) in the catalog: id, family_id, sku, variant_name, prices (price_excluding_tax / price_including_tax), active flags, codes, suppliers, version. The product NAME lives on the product family: add includes=["families"] to get it. Paginate with next_after (sto
- lightspeedxseries_get_product: One product (variant) by id, with its prices, codes, suppliers and outlet taxes. GET /products/{product_id}.
- lightspeedxseries_search_products: Filter products by SKU, brand, supplier, tag, product type or variant parent. Uses offset paging: pass next_offset to continue (null = last page). GET /search?type=products.
- lightspeedxseries_get_inventory_levels: Stock on hand per product per outlet: product_id, location_id (= outlet id), current_inventory_level, reorder threshold/amount, quantity_to_procure, average cost, total cost, supplier.

Paginate wi
- lightspeedxseries_get_consignment: One consignment (stock order, transfer, stocktake or return) by id. GET /consignments/{consignment_id}.
- lightspeedxseries_list_consignment_products: The product lines of one consignment: product_id, SKU, ordered count, received quantity, cost. Paginate with next_after (stop when data is empty). GET /consignments/{consignment_id}/products.
- lightspeedxseries_list_sales: Sales in version order, oldest changes first: the way to sync everything that changed. It has NO date filter: for a period use search_sales or sales_summary. Each sale: id, date, invoice_number, state, customer_id, source (outlet, register, user), payments, line_items, totals. Pa
- lightspeedxseries_get_sale: One sale by id with its line items, payments, taxes and totals. GET /sales/{sale_id}.
- lightspeedxseries_search_sales: Find sales by date range (UTC), state, outlet, register, user, customer, payment type, product or invoice number. Uses offset paging: pass next_offset to continue (null = last page). Replies can be large: for totals over a period use sales_summary instead of paging through this. 
- lightspeedxseries_sales_summary: Totals for a period computed here from up to max_pages x page_size sales, so a report needs ONE tool call instead of dozens: sale count and net / tax / gross (tax-inclusive) totals, plus breakdowns by state, UTC day, outlet and payment type name, and the top products by quantity.

- lightspeedxseries_create_customer: WRITE: create a new customer. Give at least a first name, last name or company name. Check search_customers first so you do not create a duplicate. POST /customers.
- lightspeedxseries_update_customer: WRITE: change fields of an existing customer. Only the fields you pass change: the tool first reads the customer and sends the vendor its full record with your changes applied (the vendor's update is a full PUT). Cannot delete a customer or change balances. Lightspeed offers no p
- lightspeedxseries_update_product_prices: WRITE: set the selling price of one product (variant). Pass price_excluding_tax or price_including_tax as a decimal string such as "24.99" (set one; the store's tax setting decides which the till uses). Nothing else on the product changes. Read the product first and confirm the n
- lightspeedxseries_set_product_stock: WRITE: set the stock on hand (current_amount) and/or the reorder point and reorder amount of ONE product at ONE outlet. current_amount is the NEW TOTAL on hand, not a change: it overwrites the count, so sales made since you last read it are lost from the count. Read get_inventory
