Frequently asked questions
What is the Mercury MCP server?
It is a Model Context Protocol (MCP) server — a small piece of software that gives AI assistants like Claude a secure, governed connection to Mercury. Query business bank balances, transaction history, and account data in natural language, with OAuth sign-in and read-only access so the AI can analyse cash without moving money.
Is there an official Mercury MCP server?
Yes. The Mercury MCP server is an official integration, maintained by the vendor or the Model Context Protocol project, which makes it the safest default for business use. It is maintained by Mercury.
What can an AI assistant actually do with Mercury?
Through this server an assistant can work with banking, balances, transactions, cash analysis — reading from and acting on Mercury directly instead of you copy-pasting between windows. What you allow it to do is controlled by the permissions you grant.
How do I set this up for my business?
Technically-minded teams can connect an MCP server themselves; our plain-English guide to MCP explains how the pieces fit. Once it is running against real systems, the question becomes what catches it when it acts wrongly, which is what Crox's Safety Diagnostic looks at.

Already running this in production?
An agent with a live connection to your tools is a model that can act. Crox looks at what catches it when it acts wrongly: the layers around it, who can stop it, and where a near miss gets reported. Two days, one team, one model.
