Proabono for AI agents
ProAbono is subscription management software that automates billing, invoicing, and customer lifecycle tasks. Finance teams use it to run recurring billing without manual invoicing. 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 Proabono.
Check a customer's subscription read-only
Look up a customer's active subscription and billing status before answering a support question.
Get an invoice
Retrieve an invoice for a customer to resend or reference in a support ticket.
Delete a customer with approval
Remove a customer record only after finance confirms all billing has been settled.
64 Proabono actions, graded by risk.
Every Proabono action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

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

Proabono and Arc0, answered.
Can I use Proabono with Claude, ChatGPT or Cursor?
Yes. Connect Proabono 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 Proabono actions you allow.
How do users connect Proabono?
Users add their Proabono username and password 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 Proabono actions can my agent take?
64 in total: 43 read, 15 write and 6 destructive, such as “create Feature”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in Proabono?
Yes. Actions like “delete Offer” 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 Proabono too?
Yes. The same Proabono connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Proabono into your agent.
Your users connect Proabono once, under your brand. Your agent gets 64 actions behind your policies, with every call on the record.
