Frequently asked questions
How do I find my AMcards Access Token?
Log in to your account, navigate to Settings > API, and generate a new Access Token for your integration.
Can I include a gift with the card?
Yes! If your chosen template ID includes a gift (like brownies), the system will automatically process the high-fidelity gifting workflow.
How do I check if a card was delivered?
Use the get_card_sending_history tool to retrieve the high-fidelity status log of all your previous card shipments.
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.
