How to set up the CIDX MCP on JetBrains IDEs

Follow these steps to integrate the CIDX MCP with your favorite JetBrains IDE (IntelliJ IDEA, WebStorm, PyCharm, etc.) and unlock powerful documentation, code search, and agent features directly in your editor.

1. Open the JetBrains settings

   Go to Settings via File → Settings (or Ctrl+Alt+S).

2. Navigate to the MCP server section

   In the left panel, expand Tools (or AI) and click MCP Server.

3. Click the + Add new global MCP server button

   This opens a JSON editor where you can configure MCP servers.

4. Add the CIDX MCP configuration

   Delete any placeholder content and copy-paste the following configuration:

   {
     "mcpServers": {
       "cidx-mcp": {
         "command": "npx",
         "args": [
           "cidx@latest"
         ]
       }
     }
   }

   Note: If you already have other MCP servers installed, you only need to add this portion inside your mcpServers object:

     "cidx-mcp": {
       "command": "npx",
       "args": [
         "cidx@latest"
       ]
     }

   Example with another server:

   {
     "mcpServers": {
       "cidx-mcp": {
         "command": "npx",
         "args": ["cidx@latest"]
       },
       "dummy-server": {
         "command": "dummy",
         "args": ["--mcp"]
       }
     }
   }

5. Save and verify the configuration

   1. Click Save or press Ctrl+S to save.
   2. If successful, you'll see a green status indicator next to cidx-mcp.
   3. If you see a red indicator, make sure you've completed the login step correctly.
