}Frequently asked questions
What is the Convex 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 Convex. Introspect and query your apps deployed to Convex. Access real-time backend data, functions, and schema.
Is there an official Convex MCP server?
Yes. The Convex 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 Convex.
Is the Convex MCP server hosted, or do I run it myself?
It runs locally. Your AI client starts it on your own machine with npx, and it talks to the client over standard input and output rather than the network.
Do I need an API key for the Convex MCP server?
No. It runs on your machine with your own permissions, so there is no key to create.
What can an AI assistant actually do with Convex?
Through this server an assistant can work with backend, real-time data, functions, schema — reading from and acting on Convex 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?
The setup section above has copy-paste config for Claude Code, Claude Desktop, Cursor and VS Code. 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.
