Skyfire for AI agents

Skyfire issues tokens that let AI agents pay for services and verify their identity to sellers, giving agent-to-agent transactions a metering and settlement layer. 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 Skyfire.

01

Check wallet balance before paying

Check a buyer's wallet balance before issuing a payment token, so an agent doesn't attempt a charge it can't cover.

02

Create a scoped payment token

Create a KYA+PAY token limited to one purchase, so a seller can verify and charge only that transaction.

03

Review token charges after the fact

List the charges made against a token to audit what an agent actually spent on a buyer's behalf.

02 · ACTIONS

16 Skyfire actions, graded by risk.

Every Skyfire 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 Skyfire connects.

Users add their Skyfire 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 Skyfire 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

Skyfire and Arc0, answered.

Q01

Can I use Skyfire with Claude, ChatGPT or Cursor?

Yes. Connect Skyfire 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 Skyfire actions you allow.

Q02

How do users connect Skyfire?

Users add their Skyfire 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 Skyfire actions can my agent take?

16 in total: 10 read, 6 write and 0 destructive, such as “create Skyfire KYA Token”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Skyfire?

Yes. Allow read actions and deny writes in the Skyfire policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Skyfire too?

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