Agent Card Scanner Public beta

Meet the agent.
Read the evidence.

A clearer view of any A2A Agent Card. Check its signatures, understand its declarations, and know what needs attention.

No agent tasks invoked

Enter a public domain or an exact Agent Card URL. No setup on the agent required.

A fictional card, real inspection.
Inspection options

Advisory findings never fail this threshold.

Use only public keys. Supplied keys replace network key discovery.

What you get

A card is a starting point.
Make it an informed one.

01 / Inspect

See what is declared.

Read the card’s core fields and advertised settings, from interfaces to authentication declarations.

02 / Verify

Know what the signature proves.

Separate verified integrity, missing keys, unsigned cards, and signatures that need attention.

03 / Act

Take evidence with you.

Get concrete next steps. Download the JSON report or run the same policy in your terminal.

Static card inspection only. A valid signature does not establish operator identity or runtime safety. Understand the checks

For your workflow

Same evidence.
In your terminal.

Before a merge. After a deployment.
Whenever you need a second look.
