## About Mercury MCP with LuumenAI

Ask about balances mid-incident or mid-close without opening the banking dashboard. Mercury MCP is Mercury's official server, in beta, and it is read-only: accounts, cards, statements, attachments, customers, and invoices come back as data, and mutations are blocked on Mercury's side. Luumen connects over DCR OAuth. Every call, including MERCURY_MCP_GET_ACCOUNTS, is classified as a write here, so expect an approval prompt by default; administrators can adjust that per tool.

## Example tools

Write and destructive (30 in total, approval required by default):

- `MERCURY_MCP_GET_ACCOUNT` — Get account by ID
- `MERCURY_MCP_GET_ACCOUNT_CARDS` — Retrieve all debit and credit cards associated with a specific account.
- `MERCURY_MCP_GET_ACCOUNTS` — Retrieve a paginated list of accounts.
- `MERCURY_MCP_GET_ACCOUNT_STATEMENTS` — Retrieve a paginated list of monthly statements for a specific account.
- `MERCURY_MCP_GET_ATTACHMENT` — Retrieve attachment details including download URL
- `MERCURY_MCP_GET_CURRENT_DATE` — Get the current date in the format.
- `MERCURY_MCP_GET_CUSTOMER` — Retrieve details of a specific customer by their ID
- `MERCURY_MCP_GET_INVOICE` — Retrieve details of an invoice by its ID
