Requirements

• Node.js 16 or higher
• Julia 1.9 or higher installed and accessible in PATH
• Claude Desktop

Configuration

Add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "juliadoc": {
      "command": "npx",
      "args": [
        "-y",
        "@jonathanfischer97/server-juliadoc"
      ],
      "env": {
        "JULIA_PROJECT": "/path/to/your/julia/project"
      }
    }
  }
}

The server will use:

• Your specified Julia project if JULIA_PROJECT is set in the config
• The default global Julia environment if no project is specified
• Your system’s default Julia installation (must be accessible in PATH)
