Altoviz for AI agents

Altoviz is a cloud billing and invoicing platform for small businesses, covering customers, products, quotes, and payments. Bookkeepers and business owners use it to issue invoices and track receivables. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

01 · USE CASES

What agents do in Altoviz.

01

Create and send a sale invoice

Create an invoice for a customer and download the PDF so it can be sent out.

02

Look up a customer before invoicing

Find an existing customer or contact by email to avoid creating a duplicate record.

03

Require approval before deleting an invoice

Deleting a sale invoice or customer record is destructive and should be confirmed before it runs.

02 · ACTIONS

67 Altoviz actions, graded by risk.

Every Altoviz action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

04 · AUTH AND DATA

How Altoviz connects.

Users add their Altoviz api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Altoviz connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Altoviz and Arc0, answered.

Q01

Can I use Altoviz with Claude, ChatGPT or Cursor?

Yes. Connect Altoviz to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Altoviz actions you allow.

Q02

How do users connect Altoviz?

Users add their Altoviz api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Altoviz actions can my agent take?

67 in total: 41 read, 16 write and 10 destructive, such as “create Contact”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Altoviz?

Yes. Actions like “delete Product” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Altoviz too?

Yes. The same Altoviz connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
