Keyzy for AI agents

Keyzy is a software licensing platform that issues, validates, and manages license keys and device activations for software vendors and independent developers selling paid products. 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 Keyzy.

01

Validate a customer license key

Check whether a license is active and within its activation limit before granting a customer access.

02

List active device activations

Pull the activations tied to a license so support can see which devices are currently registered.

03

Block license deletion without review

Hold a request to delete a license for approval, since it permanently revokes a customer's access.

02 · ACTIONS

14 Keyzy actions, graded by risk.

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

03 · HOW IT WORKS

Keyzy in three steps.

  1. 01Your users connect KeyzyThey add their Keyzy api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “update Activation” can wait for the user, and “delete License” can be denied outright.
  3. 03Any agent can actYour agent calls Keyzy through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('keyzy', {
  read: 'allow',
  write: 'ask',        // update_activation
  destructive: 'deny',  // delete_license
})

# Claude Code: the same connection, one URL

04 · AUTH AND DATA

How Keyzy connects.

Users add their Keyzy 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 Keyzy 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

Keyzy and Arc0, answered.

Q01

Can I use Keyzy with Claude, ChatGPT or Cursor?

Yes. Connect Keyzy 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 Keyzy actions you allow.

Q02

How do users connect Keyzy?

Users add their Keyzy 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 Keyzy actions can my agent take?

14 in total: 6 read, 6 write and 2 destructive, such as “update Activation”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Keyzy?

Yes. Actions like “delete License” 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 Keyzy too?

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