What the Mercury MCP connector can do
Mercury's official MCP server (Beta) for read-only access to your Mercury business banking data — accounts, balances, transactions, cards, recipients, statements, and treasury. Cannot initiate transactions or modify account data; all mutations are blocked server-side.
