Overview

What is JetBrains MCP Server Plugin?

JetBrains MCP Server Plugin was a plugin that provided the server-side implementation of the Model Context Protocol (MCP) for JetBrains IDEs, enabling integration between Large Language Models (LLMs) and the IDE. It has been deprecated; the core functionality is now built into all IntelliJ‑based IDEs starting with version 2025.2.

How to use JetBrains MCP Server Plugin?

The plugin required installation of the JetBrains MCP Proxy and a compatible JetBrains IDE (e.g., IntelliJ IDEA, WebStorm). Third‑party developers could implement custom MCP tools via the plugin’s extension point system, following the guidelines in the demo plugin. Because the plugin is deprecated, please refer to the official documentation for the built‑in MCP functionality.
