​
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.
  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.tyms.io/full and reconnect (complete OAuth again if your client requires it). See Endpoints and Capabilities.
