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 LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
