CertSeal for AI agents

CertSeal issues and manages verifiable digital certificates, letting an organization batch-generate credentials for things like course completions or event attendance. 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 CertSeal.

01

Issue a batch of certificates

Issue certificates to a batch of recipients once a course or event has wrapped up.

02

Look up a recipient's certificate

Look up a specific recipient's certificate to confirm it was issued correctly.

03

Confirm before deleting a recipient

Confirm before deleting a recipient record, since their issued certificates lose that reference.

02 · ACTIONS

21 CertSeal actions, graded by risk.

Every CertSeal 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

CertSeal in three steps.

  1. 01Your users connect CertSealThey add their CertSeal api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, writes like “create Batch” can wait for the user, and “delete Recipient” can be denied outright.
  3. 03Any agent can actYour agent calls CertSeal 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('certseal', {
  read: 'allow',
  write: 'ask',        // create_batch
  destructive: 'deny',  // delete_recipient
})

04 · AUTH AND DATA

How CertSeal connects.

Users add their CertSeal 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 CertSeal 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

CertSeal and Arc0, answered.

Q01

Can I use CertSeal with Claude, ChatGPT or Cursor?

Yes. Connect CertSeal 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 CertSeal actions you allow.

Q02

How do users connect CertSeal?

Users add their CertSeal 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 CertSeal actions can my agent take?

21 in total: 10 read, 9 write and 2 destructive, such as “create Batch”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in CertSeal?

Yes. Actions like “delete Recipient” 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 CertSeal too?

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