Jetbrains MCP Server

JetBrains IDE proxying for AI clients that is now officially deprecated.

Overview

This MCP server was designed to proxy requests between AI clients, such as Claude Desktop or VS Code, and running JetBrains IDEs. It relied on a specific IDE plugin to facilitate communication between the development environment and external AI assistants. However, this repository is no longer maintained. JetBrains has integrated native MCP support directly into all IntelliJ-based IDEs starting with version 2025.2, rendering this standalone NPM package obsolete.

Our verdict

This server carries a high risk rating with a security score of 42/100. Because the project is explicitly marked as deprecated and has not received a commit in over 200 days, users should avoid this package entirely. Instead of using this legacy proxy, developers should migrate to the built-in MCP functionality now included natively within modern IntelliJ-based IDEs.

Setup

Claude Desktop

{
  "mcpServers": {
    "mcp-jetbrains": {
      "args": [
        "-y",
        "@jetbrains/mcp-proxy"
      ],
      "command": "npx"
    }
  }
}

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.

No read-only mode — running this grants full read/write access.
No built-in authentication — anyone with access to this config can invoke every tool it exposes.

Frequently asked questions

›Is this project still being updated?

No, this repository is no longer maintained as the functionality has been integrated directly into IntelliJ-based IDEs since version 2025.2.

›What are the Node.js version requirements for this server?

The MCP proxy requires Node.js version 18 or later. It will not work on Node 16.

›How can I connect to a specific instance if I have multiple IDEs running?

You can specify a custom IDE port or host address by adding 'IDE_PORT' or 'HOST' environment variables to your MCP server configuration.

›Why is the plugin unable to detect my Node.js installation on macOS?

This often occurs when using nvm (Node Version Manager). You can resolve this by creating a symbolic link in '/usr/local/bin' that points to your nvm npx executable.

›How do I use this server with external clients or Docker containers?

You must enable 'Can accept external connections' in your IDE's debugger settings and configure the server using your machine's LAN IP address and the specific IDE port instead of host.docker.internal.

›Where should I report bugs for the built-in MCP functionality?

Please use the JetBrains YouTrack issue tracker for bugs or feature requests related to the MCP functionality now built into the IDE.
