# Tools

The MCP server builds its tools from the [Open API](/developers/api/en): each endpoint group (business area) becomes a tool named `pos_<area>`. Areas with both read and write actions are split into two tools, the write tool ending in `_write`, so clients can allow each kind separately.

Each tool takes an `action` parameter that selects the operation, for example `pos_order` with `action: "list"` to list orders. The list below is generated from the current Open API, the same list your client receives.

## Looking up parameters

To keep the tool list small, clients only receive action names. Before calling an action, the AI calls `pos_describe` to get its full parameters and description:

```json
{ "tool": "pos_order", "action": "list" }
```

You never need to call `pos_describe` yourself; the AI does it when needed.
