Best When

You are on a JetBrains IDE older than 2025.2 and need MCP connectivity to an external AI client, or you need Docker container IDE access via the JVM proxy.

Avoid When

You are on JetBrains 2025.2 or newer — use the built-in MCP server instead. This package is officially deprecated.

Use Cases

  • • Connecting Claude Desktop to IntelliJ IDEA, PyCharm, or WebStorm for AI-assisted coding
  • • Routing MCP requests to a JetBrains IDE running inside a Docker container
  • • Multi-IDE setups where specific port routing is needed to target a particular IDE instance
  • • Legacy setups on JetBrains IDE versions prior to 2025.2

Not For

  • • JetBrains IDE 2025.2+ users (built-in MCP makes this package unnecessary)
  • • Non-JetBrains editors (VS Code, Neovim, Emacs, etc.)
  • • Users on Node.js 16 (requires Node 18+)
