Frequently asked questions
Can the AI Agent process a direct credit card charge?
No, for security reasons and PCI compliance, the agent uses Payment Intents and Paylinks. The end user still securely completes the payment.
Does this MCP integration support partial refunds?
Yes, you can instruct the AI to refund a specific amount. If no amount is provided, the transaction is fully refunded.
Can I use the agent to mass-delete my customer base?
No, destructive mass operations are not exposed to the AI agent to prevent accidental data loss in your Blink Payment account.
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.
