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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Blink Payment MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
