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
