Free forever for local development and manual testing on your laptop.
For developers and teams shipping production AI agents.
Pay once, use forever. No recurring monthly subscriptions.
Every rule is grounded in the official Linux Foundation and Google Cloud Agent2Agent specification.
Missing cryptographic signatures. Makes it easy for bad actors to impersonate your agent.
Uses weak symmetric keys (HS256) or points to an untrusted external key server.
Interfaces or auth URLs using unencrypted http:// instead of secure https://.
Endpoints pointing to localhost, private internal IPs, or cloud metadata (169.254.169.254).
Hidden system prompt overrides or invisible zero-width Unicode characters in descriptions.
High-privilege actions (shell commands, database queries, payments) without login requirements.
Uses legacy password or implicit flows that are officially deprecated in the A2A spec.
API keys passed via query parameters, leaking secrets into browser history and server logs.
Enabling extended card features without declaring authentication requirements.
Missing core fields required by the standard: name, description, supported interfaces, or skills.
Activate in seconds using whichever method fits your workflow best.
Pass directly in your terminal command.
Set once in your shell or .env file.
Save in repository secrets for automated PR gating.
Your license key is generated immediately upon successful checkout and sent to your PayPal email address.
No. a2a-audit runs 100% locally on your machine or CI/CD runner. It never uploads your files or agent cards anywhere. License key validation happens entirely offline using built-in public-key cryptography.
Yes. Both the Pro and Lifetime licenses authorize your organization to scan all of your public and private repositories.
An Agent Card (agent-card.json) is the identity and capabilities file defined by the Linux Foundation and Google Cloud A2A specification. It tells multi-agent systems who an agent is and what skills it can perform.
