MCP server

Let your own AI tools read the ERP

The Tathven MCP server lets AI tools outside the ERP, such as Claude Code, Claude Desktop or any MCP client, read your organisation’s records through read-only tools. Nothing is reachable until an administrator switches it on, chooses the user the tools act as, and chooses which tools they see.

An add-on · off until an administrator switches it on

For teams that work in AI tools

For teams that already work in Claude or another AI tool, and want it to look things up in the ERP’s own records.

In the AI tool you already use

Claude Code, Claude Desktop or any other MCP client can look up sale orders, stock and reference data in your own ERP.

Separate from the assistant

It works on its own. It does not need the ERP’s built-in AI assistant, and the assistant does not need it.

Large results as a file

A large result comes back as a link to a saved file instead of inline text.

You decide what it can reach

An administrator controls it on one page: Admin › Settings › AI Assistant › MCP Server.

Off until you switch it on

An organisation is open to MCP clients only once an administrator turns it on. Turn it off and every client is cut off.

One user, chosen by you

Clients act as one IAM user you choose, best a dedicated one. Only that user’s access keys are accepted, and every look-up runs as that user.

Tool groups you switch on

Choose which groups clients may see: reference data, sales, stock. A client sees only the tools of the groups that are on. A group switched on for a user without its rights is not offered, and the page says so.

A key for each client

Issue one access key per client from the same page. The secret is shown once. Revoke a key to cut that one client off.

Changes within a minute

Switching off, changing the groups or revoking a key takes effect within about a minute, with no restart.

Security

Read-only

All 21 tools only read. None of them can change a record.

Only the groups its user may see

A tool group is offered only when the chosen user holds its rights: Sales needs Sale Orders, Stock needs Items and Stock Balance. Stock documents also follow that user’s own document rights.

The ERP checks every connection

Before it serves anything, the server asks the ERP whether your organisation is open to MCP, whether the key belongs to the chosen user, and which tool groups are on.

No passwords on the server

One server serves every organisation and holds no customer passwords. Each client brings its own organisation key and access key.

Keys you can rotate

Two keys can be active per user at a time, so you can issue a new key, move the client over and revoke the old one without a gap.

Never in the address

The credential travels in a header. A credential put in the address is ignored.

The tools

21 read-only tools in three groups.

Reference data

Units and branches, countries, currencies, departments and their roles, units of measure and dispatch modes.

Sales

Sale orders by code, customer, item, unit, date or status; an order with its lines; order statuses, what has shipped and what remains; order totals for a date range; subscriptions and coupons.

Stock

The item catalogue and each item’s record; balances by unit and department; purchase orders, goods receipts, goods issues and other stock documents, with their lines.

Connect in four steps

An owner or administrator does all four.

1. Create the user

Create a dedicated IAM user and grant it Read on what the tools should see: Sale Orders for sales; Items and Stock Balance for stock (plus Purchase Orders, Goods Receipts and Goods Issues for stock documents). A group whose rights the user lacks is not offered.

2. Switch it on

Under Admin › Settings › AI Assistant › MCP Server, open the organisation to MCP clients, choose that user and the tool groups, and save.

3. Issue a key

Name the key after the client, issue it and copy the secret. It is shown only once.

4. Connect the client

Paste the ready-made configuration from the page: a Claude Code command or a JSON config. The client sends one header, Authorization: Bearer <org-key>.<access-key-id>.<secret>.
