Mercury

About

Ask your agent about your runway, safely

Mercury bundles business checking, company cards, expense management, invoicing and bill pay at $0/mo, with paid tiers for advanced invoicing and a relationship manager. Its MCP server (in beta) gives AI tools read access to transactions, balances and recipients. Write actions are opt-in: an agent can draft payments and transfers, but a human must approve them in Mercury.
