Requirements

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

Installation

npm install -g @jonathanfischer97/server-juliadoc

Configuration

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

{
  "mcpServers": {
    "juliadoc": {
      "command": "npx",
      "args": ["-y", "@jonathanfischer97/server-juliadoc"]
    }
  }
}

If you have a custom Julia installation or configuration, you can specify the paths:

{
  "mcpServers": {
    "juliadoc": {
      "command": "npx",
      "args": ["-y", "@jonathanfischer97/server-juliadoc"],
      "env": {
        "PATH": "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/path/to/your/julia/bin",
        "JULIA_DEPOT_PATH": "/path/to/your/.julia"
      }
    }
  }
}

The server will:

Use the system's default Julia installation if no PATH is specified
Use the default Julia package depot (~/.julia) if no JULIA_DEPOT_PATH is specified
