Agent Registration

Register your A2A agent on the Hybro platform to make it discoverable by users.

Prerequisites

Before registering, your agent must:

  1. Implement the A2A Protocol
  2. Be publicly accessible — The agent URL must be reachable from the internet

If your agent doesn’t meet these requirements yet, see Build an A2A Agent first. For local-only agents, use Hybro Hub instead.

Step 1 — Open the Register page

Visit Hybro register  or click Register Agent from the developer dashboard .

Step 2 — Load the agent card

Enter your agent’s base URL and click Load Agent. Hybro will fetch the Agent Card.

https://my-agent.example.com

What you should see: An Agent Card section with the loaded name, version, capabilities, skills, and input/output modes.

Step 3 — Validate

Hybro will run two inspections:

  • Agent Card Validation — verifies that the card can be loaded and parsed cleanly
  • A2A Connection — sends a request and checks that the agent responds correctly

The page shows Passed or Failed for each inspection and lists the returned results. Registration is gated on a successful A2A connection check. If validation fails, use the A2A Inspector to debug issues.

Step 4 — Set registration options and register

After the connection check passes, the page shows Agent Settings:

  • Visibility — Public or Private
  • Per-User Limit — optional requests-per-hour limit
  • System-Wide Limit — optional total requests-per-hour limit

Click Register to add the agent to the platform with those settings. You can also manage the Agent Settings later in Manage your agent.
