The JetBrains MCP Proxy Server functions as a communication bridge between clients (like VS Code or Claude) and JetBrains IDEs, allowing them to interact with your IDE directly. This enables AI tools to access your code context, providing more relevant and accurate responses.
Use the one-click installation options:
Add the configuration to your VS Code User Settings (JSON):
Ctrl + Shift + P and type Preferences: Open User Settings (JSON){
"mcp": {
"servers": {
"jetbrains": {
"command": "npx",
"args": ["-y", "@jetbrains/mcp-proxy"]
}
}
}
}
Alternatively, you can add it to .vscode/mcp.json in your workspace:
{
"servers": {
"jetbrains": {
"command": "npx",
"args": ["-y", "@jetbrains/mcp-proxy"]
}
}
}
To use with Claude Desktop:
Find your config file:
~/Library/Application\ Support/Claude/claude_desktop_config.json%APPDATA%/Claude/claude_desktop_config.jsonAdd the following to your configuration:
{
"mcpServers": {
"jetbrains": {
"command": "npx",
"args": ["-y", "@jetbrains/mcp-proxy"]
}
}
}
If you're running multiple IDEs with MCP server:
"env": {
"IDE_PORT": "<port of IDE's built-in webserver>"
}
By default, the server connects to 127.0.0.1:
"env": {
"HOST": "<host/address of IDE's built-in webserver>"
}
"env": {
"LOG_ENABLED": "true"
}
Problem: Error message: Cannot find module 'node:path'
Solution:
Problem: MCP Server Plugin can't detect Node.js installed via nvm
Solution: Create a symbolic link to your nvm npx executable:
which npx &>/dev/null && sudo ln -sf "$(which npx)" /usr/local/bin/npx
Problem: 404 errors or connection failures when accessing from external clients or Docker containers
Solution:
Enable external connections in your JetBrains IDE:
Configure with LAN IP and Port:
mcpServers:
intellij:
type: stdio
command: sh
args:
- "-c"
- "IDE_PORT=YOUR_IDEA_PORT HOST=YOUR_IDEA_LAN_IP npx -y @jetbrains/mcp-proxy"
Replace YOUR_IDEA_PORT with your IDE's debug port and YOUR_IDEA_LAN_IP with your computer's local network IP (e.g., 192.168.0.12).
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "jetbrains" '{"command":"npx","args":["-y","@jetbrains/mcp-proxy"]}'See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:
{
"mcpServers": {
"jetbrains": {
"command": "npx",
"args": [
"-y",
"@jetbrains/mcp-proxy"
]
}
}
}To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json~/.config/Claude/claude_desktop_config.json2. Add this to your configuration file:
{
"mcpServers": {
"jetbrains": {
"command": "npx",
"args": [
"-y",
"@jetbrains/mcp-proxy"
]
}
}
}3. Restart Claude Desktop for the changes to take effect
