Prerequisites

Before you expose an agent graph:
  • Publish at least one version of the agent graph. See Agent Graph publishing.
  • Hold Developer role or higher for Graph Studio save/publish actions.
  • Have permission to call registry APIs (assistants.flows:create via the gateway POST /a2a-registry).
  • Run in a local or dev environment where Configure Agent is visible in Graph Studio (see Overview — Access and environment).
Associated tools referenced by the graph must be published before you can select them in step 1 of the wizard.

​
Open the expose flow

  1. Open Graph Studio for your project.
  2. Select the agent graph you want to expose.
  3. In the canvas header, click Configure Agent (dev environments only).
  4. In the Expose as Agent modal, review any existing test/live builds and hosted URLs.
  5. Click Create New Build to open the Expose as External Agent wizard.
Expose as Agent modal with hosted URL and Create New Build The modal explains that publishing an Agent Card enables the graph as a hosted agent callable via the A2A protocol. Use See Agent builds to jump to Agent Cards for the project.

Wizard steps

The wizard has three steps. Step labels in the UI:
StepLabelPurpose
1Agent Build ConfigPick agent graph version and published tools
2Additional ConfigOptional export of tools/variables to the build
3Configure the Agent cardAgent Card identity, skills, tags, visibility
Primary actions: Next (steps 1–2), Attach Agent Card (step 3).

​
Step 1 — Agent Build Config

Wizard step 1: Agent Build Config with graph version and tools Confirm the Agent Config:
  • Agent Graph accordion — select the flow version to register (name, version number, version notes, timestamp).
  • Tools Associated accordion — select published tool versions linked to the graph. Unpublished tools show a Publish action inline.
Validation requires a selected graph version. If tools exist on the graph, at least one published tool must be selected.

​
Step 2 — Additional Config

Variables and Secrets:
  • Toggle Export to build to include predefined tools, MCP tools, or environment variables in the registry build.
  • When enabled, use tabs Predefined, MCP, and Env and search Search tools and variables…
  • For each exported row, provide a description (required).
When export is disabled, the step shows: Enable “Export value to build” to configure additional tools and variables.

​
Step 3 — Configure the Agent card

Wizard step 3: Agent Card with skills, tags, and visibility Agent Card is the identity of your agent on the Internet:
FieldNotes
Agent NameRead-only; derived from the agent graph name
Agent DescriptionEditable summary for catalog and A2A clients
SkillsAdd skills with unique name, description, Input Modes, and Output Modes (MIME types)
Discoverability TagsTags help agents appear in search and Discovery filters
Visibility & accessPublic — discoverable by any A2A-compatible agent or user with a valid API key. Organisation — visible only within your organisation
Auth SchemesPlatform default: use your Phinite organisation API key
Refine CardOptional AI refinement (refine_prompt_for: "a2a") to improve description and skills
Click Attach Agent Card to submit. The UI calls POST /a2a-registry?workspaceid={workspaceId} with the wizard payload (agent_card, flowid, flow_version, assistantid, tools, and optional export config).

​
After registration

Success state with registry ID and hosted test URL On success:
  • Note the Agent Registry ID and hosted A2A URL (test builds use the registry ID in the path—see Endpoints & lifecycle).
  • The success message indicates the build is available to Test.
  • Click Go to Agent Registry to open the workspace catalog.
New registrations start with deployment status test. Promote to live from Agent Cards when you are ready for production routing.
