BTCPay Server for AI agents
BTCPay Server is a self-hosted, open-source payment processor that lets a merchant accept Bitcoin directly, without a payment company sitting in between. 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 BTCPay Server.
Create a Bitcoin payment request
Generate a new payment request for an invoice, with the store and amount already attached.
Check pending payment requests
Pull the list of open payment requests for a store before following up with customers.
Confirm before canceling a payout
Confirm before canceling a pending store payout, since it cannot be reversed once approved.
16 BTCPay Server actions, graded by risk.
Every BTCPay Server action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

BTCPay Server in three steps.
- 01Your users connect BTCPay ServerThey add their BTCPay Server api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create BTCPay Server User” can wait for the user, and “cancel Store Payout” can be denied outright.
- 03Any agent can actYour agent calls BTCPay Server through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('btcpay_server', { read: 'allow', write: 'ask', // create_user destructive: 'deny', // delete_payout }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How BTCPay Server connects.
Users add their BTCPay Server 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 BTCPay Server 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

BTCPay Server and Arc0, answered.
Can I use BTCPay Server with Claude, ChatGPT or Cursor?
Yes. Connect BTCPay Server 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 BTCPay Server actions you allow.
How do users connect BTCPay Server?
Users add their BTCPay Server 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 BTCPay Server actions can my agent take?
16 in total: 8 read, 5 write and 3 destructive, such as “create BTCPay Server User”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in BTCPay Server?
Yes. Actions like “cancel Store Payout” 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 BTCPay Server too?
Yes. The same BTCPay Server connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
