How to Set Up and Use JetBrains MCP Plugin
The JetBrains MCP Server Plugin was an official JetBrains plugin that enabled LLMs to interact with JetBrains IDEs (IntelliJ IDEA, WebStorm, PyCharm, etc.) via the Model Context Protocol. It exposed IDE capabilities—such as file navigation, code editing, and project inspection—as MCP tools callable by AI assistants. Note that this plugin is now deprecated: its functionality has been integrated directly into all IntelliJ-based IDEs starting with version 2025.2, so no separate plugin installation is required on modern versions.
Prerequisites
- A JetBrains IDE (IntelliJ IDEA, WebStorm, PyCharm, etc.) version 2024.x or earlier (for the plugin); 2025.2+ has built-in MCP support
- JetBrains MCP Proxy installed (github.com/JetBrains/mcpProxy) for older IDE versions
- An MCP-compatible AI client such as Claude Desktop
- Java/Kotlin development knowledge if implementing custom MCP tool extensions
Check your IDE version
If you are using IntelliJ-based IDEs version 2025.2 or later, MCP support is built in and no plugin is needed. Refer to the official JetBrains MCP documentation instead.
Install the MCP Proxy (for IDE versions before 2025.2)
For older IDE versions, clone and set up the JetBrains MCP Proxy, which routes MCP requests between AI clients and the IDE plugin.
git clone https://github.com/JetBrains/mcpProxy.git
cd mcpProxy
npm install
npm run buildInstall the plugin in your JetBrains IDE
In your JetBrains IDE, go to Settings > Plugins > Marketplace, search for 'MCP Server', and install the JetBrains MCP Server Plugin. Restart the IDE after installation.
Configure Claude Desktop to use the MCP Proxy
Add the MCP Proxy to your Claude Desktop configuration so Claude can communicate with your JetBrains IDE.
Verify the connection
Open your JetBrains IDE with a project, then ask Claude to perform an IDE action. The plugin exposes the project context to the LLM through the proxy.
JetBrains MCP Plugin Examples
Client configuration
Configure Claude Desktop to use the JetBrains MCP Proxy, which bridges Claude to your running JetBrains IDE instance.

With the JetBrains MCP plugin connected, use these prompts to interact with your IDE through Claude.
- "Open the file src/main/App.kt in the editor"
- "Show me all files in the current project"
- "What errors are currently shown in the Problems tab?"
- "Find all usages of the 'UserService' class in this project"
- "What is the current structure of the open file?"Troubleshooting JetBrains MCP Plugin
Plugin not working on JetBrains IDE 2025.2 or later
This plugin is deprecated and no longer maintained. IntelliJ-based IDEs 2025.2+ have native MCP support built in. See the official documentation at jetbrains.com/help/idea/mcp-server.html for setup instructions.
MCP Proxy cannot connect to the IDE
Ensure the JetBrains IDE is running with an open project before starting Claude Desktop. The plugin starts its local server when the IDE loads. Check that the proxy is connecting to the correct local port that the plugin advertises.
Custom tools not appearing in Claude
Custom tools are implemented via the plugin's extension point system. Refer to the demo plugin at github.com/MaXal/mcpExtensionPlugin for a working example. Tool names must be lowercase with optional underscores and follow the Response class conventions.
