Frequently asked questions
Can my agent help me debug why a payment failed?
Yes. Ask your agent to get payment actions for a specific ID. It returns a detailed trace of everything that happened at the gateway level, identifying exactly why an authorization fell through, from CVV checks to insufficient funds.
Is it safe to manage card instruments via the AI agent?
Absolutely. The server uses Checkout.com's native Vault logic. Sensitive PANs are wrapped safely, and your API keys are encrypted at rest. The agent only interacts with tokens or vaulted IDs, maintaining high security standards.
Can I test this in sandbox before going live?
Yes. Simply choose the 'Sandbox' environment during setup and use your sandbox secret key (sk_sbox_...). This allows you to simulate transactions and vaulting logic without processing real money.
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.
