Katana (legal entity Katana MRP OU, marketed since 2022 as "Katana Cloud Inventory" and from April 2026 as a "Modern Merchant Operating System") is a cloud manufacturing ERP / inventory management platform headquartered in Tallinn, Estonia with offices in Berlin and Austin.
Vertical: Enterprise/HR/ERP, specifically cloud MRP/inventory for SMB and lower-mid-market product businesses (typically $250K–$50M revenue, often Shopify-native DTC and wholesale brands). A brand owner connects Shopify, WooCommerce, BigCommerce, and/or Amazon to Katana so that every new sales order pulls inventory in real time.
Katana is one of the most recognized SMB cloud MRP brands and the default choice for Shopify-native makers needing manufacturing. Capterra, G2, and Software Advice list thousands of verified reviews; the Shopify App Store places Katana among the top inventory/manufacturing apps.
Yes, for any product brand running Katana, the platform is the system of record for nearly every operational dataset.
Founded in 2017 in Tallinn, Estonia by Kristjan Vilosius (CEO) and Priit Kaasik, originally branded "Katana MRP" then rebranded to "Katana Cloud Inventory" in 2022 and to a "Modern Merchant Operating System" positioning in April 2026 (Business Wire).
API access historically gated behind higher-priced plans, customers on Essential / lower tiers cannot use the API at all without upgrading, even though it is their own operational data. Bulk export to Google Sheets / CSV is restricted, pushing users toward API integrations or paid add-ons to get their own data out at scale. Full sourced list under Sources below.
Common alternatives include Cin7 (Core / Omni), Unleashed Software (Access Group), Fishbowl Inventory, MRPeasy, DEAR Systems / Cin7 Core, Oracle NetSuite. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Katana MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Katana doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
