# Build export configuration

> Export tools, MCP, and env variables into builds and Agent Card versions.

When you **Build** or **Expose as A2A**, you can export additional **tools**, **MCP** connections, and **environment variables** into the immutable **Agent Build** snapshot. This ensures deployed agents and **Agent Card** versions carry the integrations external callers need.

<Note>
  Export is optional for standard channel and trigger deploys. Use it when A2A callers or registry **Browse** nodes need tool credentials bundled with the registration build.
</Note>

## Build wizard

1. Click **Build** in Graph Studio (the **Agent Graph** must be **Saved**).
2. Wait for validation and the **Build Agent** form.
3. Add a **Description**.
4. Confirm **AGENT GRAPH** version and **TOOLS** — publish any tool showing **Publish**.
5. Click **Create Build**.

## Export in Expose wizard

1. Start **Deploy** → **Deploy as A2A** (or expose flow from **Agent Builds**).
2. Complete **Agent Build Config** (Agent Graph + tools).
3. On the export step, enable **Export value for agent version**.
4. Use tabs **Predefined**, **MCP**, **Env** and search **Search tools and variables...**
5. For each exported row, provide a **description** (required).
6. Continue to the **Agent Card** step and submit.

## When to export

* External A2A callers need tool credentials bundled with the **Agent Card** version.
* Registry **Browse** nodes require `config_id` and satisfied tool/env on the registration build.
* A trigger or channel deploy must carry MCP connections not already on the **Agent Graph**.
