Xray MCP Server

A Model Context Protocol (MCP) server for generating Xray-core configurations using natural language. This server allows LLMs to create server and client configurations for various proxy protocols.

Features

• Protocol Support: VLESS, VMess, Trojan, Shadowsocks

• Transport Support: TCP, WebSocket, gRPC, XHTTP

• Security Support: None, TLS, REALITY

• Automatic Key Generation: UUID, X25519 key pairs, Short IDs, Passwords

• Configuration Validation: Syntax and semantic validation

• Example Configurations: Ready-to-use templates

• Documentation: Built-in protocol, transport, and security documentation

Installation

npm install
npm run build

Usage with Cursor

Add to your Cursor MCP settings (~/.cursor/mcp.json):

{
  "mcpServers": {
    "xray-mcp": {
      "command": "node",
      "args": ["/path/to/xray-mcp/dist/index.js"]
    }
  }
}

Available Tools

Configuration Generation

generate_server_config

Generate Xray server configuration with specified protocol, transport, and security options.

Example:

Generate a VLESS server with REALITY on port 443

generate_client_config
