Katana MCP server

What the model can do

Katana MRP manufacturing: sales orders with delivery, production and invoicing status, manufacturing orders with deadlines and costs, products and variants, current stock by location, and customers; can add and update customers, create, update, fulfil and delete sales orders, create, update and record production on manufacturing orders, raise, update and receive purchase orders, and create or update products and materials. The sync keeps sales order changes in memory.

Connect it

First connect Katana on Dashboard → Connections, then add Memtro to your client once. The Katana tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Katana connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Ask it like this

• › Which sales orders are waiting on production?
• › What is below its reorder point?
• › How many of SKU OAK-TBL-180 do we have at the Leeds warehouse?
• › Mark sales order SO-2214 as delivered.
• › Raise a purchase order to Globex Timber for 40 oak boards at the Leeds warehouse.

Questions

Is this an official Katana MCP server?

No. It is Memtro's MCP server with Memtro's Katana connector behind it: the connector reads Katana through its API with the credentials you connect on Dashboard → Connections, and Katana publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Katana?

Only when you ask, and only what it has been granted: add a customer to Katana; update a Katana customer; create a Katana sales order (reserves stock); update a Katana sales order, including marking it packed or delivered (moves stock); mark a Katana sales order packed or delivered with a fulfillment (moves stock); delete a Katana sales order (permanent); create a Katana manufacturing order; create a Katana manufacturing order for a sales order line; update a Katana manufacturing order, including completing it (moves stock); record production output on a Katana manufacturing order (moves stock); raise a Katana purchase order (the supplier is not emailed); update a Katana purchase order; receive items on a Katana purchase order (adds stock); create a Katana product; update or archive a Katana product; create a Katana material. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
