Frequently asked questions
Can I see a preview of the card before sending it?
Yes! Use the preview_greeting_card tool with your message and artwork ID. Your agent will return a preview URL (usually a PDF) so you can verify everything looks perfect.
How do I find the correct artwork ID for a design?
Simply ask the agent to list_card_artwork. It will retrieve all the available designs from your account, including their titles and unique IDs or slugs.
Does the integration support international shipping?
Yes. When using the place_greeting_card_order action, you can specify the country code (e.g., 'UK', 'AU', 'US'). Cardly handles the local printing and postage automatically.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
