base on A model context protocol server to work with JetBrains IDEs: IntelliJ, PyCharm, WebStorm, etc. Also, works with Android Studio [](https://github.com/JetBrains#jetbrains-on-github) # JetBrains MCP Proxy Server The server proxies requests from client to JetBrains IDE. ## Install MCP Server plugin https://plugins.jetbrains.com/plugin/26071-mcp-server ## Usage with Claude Desktop To use this with Claude Desktop, add the following to your `claude_desktop_config.json`. The full path on MacOS: `~/Library/Application\ Support/Claude/claude_desktop_config.json`, on Windows: `%APPDATA%/Claude/claude_desktop_config.json`. ```json { "mcpServers": { "jetbrains": { "command": "npx", "args": ["-y", "@jetbrains/mcp-proxy"] } } } ``` ## Configuration If you're running multiple IDEs with MCP server and want to connect to the specific one, add to the MCP server configuration: ```json "env": { "IDE_PORT": "<port of IDE's built-in webserver>" } ``` By default, we connect to IDE on 127.0.0.1 but you can specify a different address/host: ```json "env": { "HOST": "<host/address of IDE's built-in webserver>" } ``` To enable logging add: ```json "env": { "LOG_ENABLED": "true" } ``` ## Troubleshooting ### Node.js Version Requirements **Problem:** Error message: `Cannot find module 'node:path'` **Solution:** MCP Proxy doesn't work on Node 16. Upgrade your Node.js installation to version 18 or later. Make sure that `command` in config points to the correct Node.js version. Try to use the full path to the latest version of NodeJS. ### ### MacOS: Plugin Unable to Detect Node.js Installed via nvm **Problem:** On MacOS, if you have Node.js installed through nvm (Node Version Manager), the MCP Server Plugin might be unable to detect your Node.js installation. **Solution:** Create a symbolic link in `/usr/local/bin` pointing to your nvm npx executable: ```bash which npx &>/dev/null && sudo ln -sf "$(which npx)" /usr/local/bin/npx ``` This one-liner checks if npx exists in your path and creates the necessary symbolic link with proper permissions. ### Using MCP with External Clients or Docker Containers (LibreChat, Cline, etc.) **Problem:** When attempting to connect to the JetBrains MCP proxy from external clients, Docker containers, or third-party applications (like LibreChat), requests to endpoints such as http://host.docker.internal:6365/api/mcp/list_tools may return 404 errors or fail to connect. **Solution:** There are two key issues to address: 1. Enable External Connections: In your JetBrains IDE, enable "Can accept external connections" in the _Settings | Build, Execution, Deployment | Debugger_. 2. Configure with LAN IP and Port: Use your machine's LAN IP address instead of `host.docker.internal` Explicitly set the IDE_PORT and HOST in your configuration Example configuration for LibreChat or similar external clients: ```yaml 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 (found in IDE settings) `YOUR_IDEA_LAN_IP` with your computer's local network IP (e.g., 192.168.0.12) ## How to build 1. Tested on macOS 2. `brew install node pnpm` 3. Run `pnpm build` to build the project ", Assign "at most 3 tags" to the expected json: {"id":"13305","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
