# Read-only vs full

> Choose the right Tyms MCP endpoint for lookups versus bookkeeping.

| Need                                                             | Use                            |
| ---------------------------------------------------------------- | ------------------------------ |
| Ask questions, analyze books, pull reports                       | `https://mcp.usetyms.com`      |
| Bookkeep, create invoices/bills, post payments, manage inventory | `https://mcp.usetyms.com/full` |

## Read-only

Best when you want Claude or ChatGPT to:

* Answer questions about your books
* List invoices, bills, expenses, contacts, and inventory
* Run financial reports

The assistant **cannot** create, update, or delete records on this endpoint.

## Full (read + write)

Best when you intentionally want the assistant to:

* Create or update invoices, bills, expenses, income, journals, and more
* Record payments
* Manage inventory (sell / restock)
* Convert quotes and purchase orders
* Use Adam to create records from plain-language descriptions

<Warning>
  The **/full** endpoint can create, update, and delete real business data. Prefer read-only unless you need write access.
</Warning>

## Recommended pattern for teams

1. Start everyone on **read-only**.
2. Enable **/full** only for trusted workflows.
3. Keep tool confirmation / human approval on for destructive actions (delete, payment posting, conversions).

## Switching access

If you only see list/get tools, you are connected to the read-only endpoint. To get write tools, update the connector URL to `https://mcp.usetyms.com/full` and reconnect (complete OAuth again if your client requires it).
