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.
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.
