Frequently asked questions
How do I get a Mercado Pago Access Token?
Go to your Mercado Pago account, navigate to Developers > Your Integrations > Production Credentials (or Sandbox), and copy your Access Token. It starts with 'APP_USR-' for production.
Can I generate Pix payments?
Yes! Use the create_pix_payment action. It generates a Pix transaction and returns QR Code data that can be displayed for the payer to scan and pay instantly.
Can I issue refunds?
Yes! Use the refund_payment action with a payment_id. If you omit the amount, it performs a full refund. If you provide an amount, it performs a partial refund.
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.
