Frequently Asked Questions
How does Mercury MCP help me track my company's cash flow? +
It gives you a real-time, aggregated view of your money. By connecting to all linked accounts and pulling data through list_transactions and get_balance, you can instantly see where the funds are coming from and going to.
Can I use Mercury MCP to check if clients paid their invoices? +
Yes. You can ask your agent for a report on outstanding payments by using list_invoices and list_customers, which tells you exactly who owes money and when it was due.
What kind of transactions can I review with Mercury MCP? +
You can review almost anything—from large vendor payments to small daily expenses. The tool pulls transaction history across all your accounts, letting you filter by date range or amount easily.
Is this better than just logging into the Mercury website? +
It's faster and more conversational. Instead of navigating menus to find a balance or a specific transaction group, you simply ask your agent, and it retrieves and formats the answer for you.
Does Mercury MCP help me manage payment details? +
Yes. You can check saved wire transfer and ACH recipient information using list_recipients before sending money out. This prevents costly errors from wrong bank details.
Can I view balances and recent transactions? +
Yes. You can query balances for all accounts and list recent incoming/outgoing transactions.
How does Mercury authentication work? +
Mercury uses a Bearer token (API Token) against api.mercury.com/api/v1. Tokens must be generated with read-only scopes.
Can I initiate money transfers via the API? +
The standard API token allows read-only access to balances and transactions for security reasons.
