Yes! Use the get_account tool and provide the Account Identifier. Your agent will retrieve the current balance and available funds for that specific funding account.
How do I find the correct ID (UTID) for a specific gift card brand?
Run the get_catalog query. The agent will retrieve the full list of available brands and items, each with its unique UTID required for placing orders.
Is it possible to track if a reward has been delivered?
Absolutely. Use the get_order tool and provide the Order ID. The agent will retrieve the status, delivery details, and even the credentials if the reward is ready.

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?
