About JetBrains

JetBrains MCP Proxy Server is an official open-source model context protocol (MCP) server that proxies requests from AI clients (such as Claude Desktop) to JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, Android Studio, etc.). It enables AI assistants to interact with code in JetBrains IDEs by forwarding MCP commands to the IDE's built-in MCP server plugin. The repository is now deprecated because the core functionality has been integrated directly into all IntelliJ-based IDEs since version 2025.2, which uses SSE and JVM-based proxy and no longer requires this NPM package. For older versions, users can install the MCP Server Plugin and configure the proxy via npx in VS Code or Claude Desktop. The server supports multiple IDE instances, custom host/port settings, and logging for debugging.

FAQ

What is the JetBrains MCP Proxy Server?
It is an official MCP server that proxies requests from AI clients (like Claude Desktop) to JetBrains IDEs, allowing AI to interact with code in the IDE.
Is this project still maintained?
No, the repository is deprecated. The core functionality has been integrated into all IntelliJ-based IDEs since version 2025.2, and the built-in feature no longer requires this NPM package.
What Node.js version is required?
Node.js version 18 or later is required because the package uses features not available in Node 16.
How do I use this with Claude Desktop?
Install the MCP Server Plugin from the JetBrains Marketplace, then add the configuration block to claude_desktop_config.json with command 'npx' and args '-y @jetbrains/mcp-proxy'. Ensure the JetBrains IDE is open before restarting Claude Desktop.
Can I connect to a specific JetBrains IDE instance?
Yes, you can set the environment variable IDE_PORT to the port of the IDE's built-in web server, or HOST to specify a different address.
