Frequently asked questions
What is the JetBrains 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 JetBrains. Work on your code with JetBrains IDEs. Interact with your development environment, run actions, and navigate code.
Is there an official JetBrains MCP server?
Yes. The JetBrains 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 JetBrains.
What can an AI assistant actually do with JetBrains?
Through this server an assistant can work with ide, code navigation, refactoring, debugging — reading from and acting on JetBrains 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.
