主要特点：

• AI驱动的管理以防止即时注入攻击
• 自动配置 - CLI 工具检测并更新 MCP 配置文件，适用于光标、Claude Desktop 和 Claude 代码
• 双重连接 - 支持本地和远程MCP服务器
• 透明代理 - 工具、提示和资源自动前缀并开放

快速启动

最简单的入门方式是使用通用分析CLI工具：

这会自动更新你的MCP配置文件，并设置护栏。

MCP Guardrail

An MCP (Model Context Protocol) guardrail with built-in AI-powered moderation that aggregates multiple MCP servers into one secure interface.

Overview

The MCP Guardrail provides AI-powered security and easy configuration for your MCP (Model Context Protocol) setup. It automatically detects your existing MCP configuration files and adds a protective layer with intelligent moderation capabilities.

Key features:

• AI-powered moderation to prevent prompt injection attacks
• Automatic configuration - CLI tool detects and updates MCP config files for Cursor, Claude Desktop, and Claude Code
• Dual connectivity - supports both local and remote MCP servers
• Transparent proxying - tools, prompts, and resources are automatically prefixed and made available

Quick Start

The easiest way to get started is using the General Analysis CLI tool:

# Install the CLI tool
pip3 install generalanalysis==0.1.7

# Login to your account
ga login

# Configure MCP settings for Cursor, Claude Desktop, and Claude Code
ga configure

This will automatically update your MCP configuration files with the guardrail setup.

Usage

Direct Usage with npx

No installation required! Use directly in your Cursor or Claude Desktop MCP configuration:

{
  "mcpServers": {
    "protected_server": {
      "command": "npx",
      "args": [
        "-y",
        "@general-analysis/mcp-guard",
        "[{\"name\":\"server1\",\"command\":\"path/to/server\",\"args\":[\"arg1\"]}]"
      ]
    }
  }
}

Standalone Usage

npx -y @general-analysis/mcp-guard '[{"name":"server1","command":"path/to/server","args":["arg1"]}]'

Configuration

Local Servers (Stdio)

For local MCP servers that communicate via stdio:

{
  "mcpServers": {
    "protected_server": {
      "command": "npx",
      "args": [
        "-y",
        "@general-analysis/mcp-guard",
        "[{\"name\":\"my-local-server\",\"command\":\"node\",\"args\":[\"path/to/server.js\"]}]"
      ],
      "env": {
        "API_KEY": "your-general-analysis-api-key",
        "ENABLE_GUARD_API": "true"
      }
    }
  }
}

Remote Servers (HTTP/SSE)

For remote MCP servers accessible via HTTP or Server-Sent Events:

{
  "mcpServers": {
    "protected_server": {
      "command": "npx",
      "args": [
        "-y",
        "@general-analysis/mcp-guard",
        "[{\"name\":\"my-remote-server\",\"url\":\"https://api.example.com/mcp\"}]"
      ],
      "env": {
        "API_KEY": "your-general-analysis-api-key",
        "ENABLE_GUARD_API": "true"
      }
    }
  }
}
