JetBrains MCP Proxy Server
Official
MCP proxy server to connect JetBrains IDEs
GitHub source repository ↗
55FMRS · C
JetBrains MCP Proxy Server was an essential tool to connect JetBrains IDEs with MCP clients, but it is now deprecated and users are encouraged to migrate to the built-in MCP functionality. It works well for official JetBrains products but can be complex to configure and troubleshoot.
JetBrains MCP Proxy Server is an official but deprecated proxy server that forwards requests from MCP clients to JetBrains IDEs. It supports IntelliJ, PyCharm, WebStorm, and other IntelliJ-based IDEs, as well as Android Studio. The core functionality has been integrated into all IntelliJ-based IDEs since version 2025.2, making this NPM package no longer required.

Setup
- Install the MCP Server plugin in your JetBrains IDE (plugin ID: 26071-mcp-server). 2. Configure your client to run
@jetbrains/mcp-proxyvia npx. For example, add to Claude Desktop'sclaude_desktop_config.json:\n``json\n{"mcpServers": {"jetbrains": {"command": "npx", "args": ["-y", "@jetbrains/mcp-proxy"]}}}\n``\n3. Restart the client and ensure the JetBrains IDE is open.
claude_desktop_config.json
{
"mcpServers": {
"jetbrains": {
"command": "npx",
"args": [
"-y",
"@jetbrains/mcp-proxy"
]
}
}
}
Fit and risk
Not for
- Developers not using JetBrains IDEs
- Users needing long-term support or latest features (since deprecated, use built-in IDE functionality)
Required permissions
- Needs access to the local port of JetBrains IDE (default 127.0.0.1:6365)
- Requires running npx, so Node.js 18 or later must be installed
Risks and side effects
- Deprecated and no longer maintained, potential unpatched security vulnerabilities or compatibility issues
- Requires correct IDE port and host configuration, otherwise connection fails
- External connections may be needed for third-party clients, posing security risks
Troubleshooting
- 1. If you get `Cannot find module 'node:path'`, upgrade Node.js to version 18 or later.
- 2. On macOS with nvm, create a symlink: `which npx &>/dev/null && sudo ln -sf "$(which npx)" /usr/local/bin/npx`.
- 3. For external clients or Docker, enable 'Can accept external connections' in IDE settings and use LAN IP and port in environment variables.
