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.
What agents do in Altoviz.
Create and send a sale invoice
Create an invoice for a customer and download the PDF so it can be sent out.
Look up a customer before invoicing
Find an existing customer or contact by email to avoid creating a duplicate record.
Require approval before deleting an invoice
Deleting a sale invoice or customer record is destructive and should be confirmed before it runs.
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.

Altoviz in three steps.
- 01Your users connect AltovizThey add their Altoviz api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create Contact” can wait for the user, and “delete Product” can be denied outright.
- 03Any agent can actYour agent calls Altoviz through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('altoviz', { read: 'allow', write: 'ask', // create_contact destructive: 'deny', // delete_product }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
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 →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Altoviz from any agent.

Altoviz and Arc0, answered.
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.
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.
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.
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.
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.
