3x-ui MCP Server

MCP (Model Context Protocol) server for 3x-ui — an Xray/V2Ray proxy management panel. Exposes the 3x-ui HTTP API as MCP tools so LLMs can manage inbounds, clients, routing rules, Xray service, and server settings.

Features

• 40 MCP tools covering the full 3x-ui API
• Automatic session management with transparent re-authentication
• Stdio transport for seamless LLM integration
• Zero external dependencies beyond the MCP SDK

Usage

Add to your MCP config (claude_desktop_config.json or .mcp.json):

{
  "mcpServers": {
    "3x-ui": {
      "command": "go",
      "args": ["run", "github.com/pyworkload/3x-ui-mcp/cmd/xui-mcp@latest"],
      "env": {
        "XUI_HOST": "http://localhost:2053",
        "XUI_USERNAME": "admin",
        "XUI_PASSWORD": "your-password"
      }
    }
  }
}

Requires Go 1.23+. First run downloads and compiles automatically, subsequent runs use cache.
