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
The /full endpoint can create, update, and delete real business data. Prefer read-only unless you need write access.
Recommended pattern for teams
- Start everyone on read-only.
- Enable /full only for trusted workflows.
- 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).
