Perplexity

Build complex reports using the MCP Server.

You can get a complete picture of current operations. Call tools like `list_orders` and `list_invoices` together to track revenue against sales volume. Need to check stock levels? Just run `search_inventory` to find details for specific items, or use `get_order` if you know the order number.

Manage supplier and product data instantly.

Keeping track of who supplies what is simple. You can call `list_vendors` to see all suppliers, or `list_formulas` to check recipes for production items. For a full list, use `list_inventory_items`. If you need item specifics, start with `get_inventory_item`.

Traceability across the supply chain.

When something goes wrong, you need to know where it was. Use `list_stock_lots` to track batches of products. This tool works alongside `list_locations` so you know exactly where those lots are stored. This helps close the loop between purchasing and sales records.
