Quick Start

Installation

pip install langprotect-mcp-gateway

Configuration

Create your MCP config file:

VS Code: ~/.config/Code/User/mcp.json
Cursor: ~/.cursor/mcp.json

{
  "mcpServers": {
    "langprotect-gateway": {
      "command": "langprotect-gateway",
      "env": {
        "LANGPROTECT_URL": "https://your-langprotect-server.com",
        "LANGPROTECT_EMAIL": "[e-mail]",
        "LANGPROTECT_PASSWORD": "your-password"
      },
      "servers": {
        "filesystem": {
          "command": "npx",
          "args": ["-y", "@modelcontextprotocol/server-filesystem", "."]
        }
      }
    }
  }
}

📝 Note: Replace LANGPROTECT_URL with your actual server URL (e.g., https://langprotect.yourcompany.com or http://localhost:8000 for local testing).

Restart Your IDE

VS Code: Ctrl+Shift+P → "Reload Window"
Cursor: Close and reopen

Done! 🎉 All your AI tool interactions are now protected.

What It Does

The LangProtect MCP Gateway intercepts all AI tool interactions and:

1. Scans for threats - Detects malicious commands, data exfiltration attempts
2. Enforces policies - Blocks access to sensitive files and dangerous operations
3. Logs everything - Complete audit trail for compliance
4. Auto-detects IDE - Tracks which IDE/tool made each request

Supported IDEs

• ✅ VS Code (with GitHub Copilot, Codeium, etc.)
• ✅ Cursor IDE
• ✅ Windsurf
• ✅ Zed Editor
• ✅ Any MCP-compatible IDE

Environment Variables

Variable	Required	Default	Description
LANGPROTECT_URL	No	http://localhost:8000	Your LangProtect server URL
LANGPROTECT_EMAIL	Yes	-	Your email address
LANGPROTECT_PASSWORD	Yes	-	Your password
DEBUG	No	false	Enable debug logging (true/false)
MCP_CONFIG_PATH	No	Auto-detected	Path to servers config (Cursor only)

⚠️ Production Setup: For production deployments, always set LANGPROTECT_URL to your actual server:

"env": {
  "LANGPROTECT_URL": "https://langprotect.yourcompany.com",
  "LANGPROTECT_EMAIL": "[e-mail]",
  "LANGPROTECT_PASSWORD": "your-password"
}

The default http://localhost:8000 is only for local development/testing.

Architecture

AI Assistant (Copilot, etc.)
         ↓
LangProtect Gateway (this package)
         ↓
    [Security Scan]
         ↓
MCP Servers (filesystem, github, etc.)

Every request is:

1. Intercepted by the gateway
2. Scanned for security threats
3. Logged to LangProtect backend
4. Forwarded to actual MCP server (if safe)
5. Response returned to AI

Dashboard

Monitor all activity at your LangProtect dashboard:

• View all AI interactions
• See security threats blocked
• Track IDE usage
• Generate compliance reports

Security

The gateway protects against:

• 🚫 Sensitive file access (.env, SSH keys, etc.)
• 🚫 Dangerous commands (rm -rf, data exfiltration)
• 🚫 SQL injection patterns
• 🚫 Hardcoded credentials in suggestions
• 🚫 Prompt injection attacks

Troubleshooting

Authentication failed:

• Check LANGPROTECT_URL, LANGPROTECT_EMAIL, LANGPROTECT_PASSWORD are correct
• Ensure LangProtect backend is accessible

Gateway not starting:

• Check Python version: python3 --version (need 3.11+)
• Check package installed: pip show langprotect-mcp-gateway

Tools not working:

• Check MCP servers are configured under "servers" section
• Restart IDE completely

For Team Leads

Quick Team Rollout:

1. Share credentials with each team member:

   Email: [e-mail]
   Password: secure-password
   Server: http://langprotect.company.com:8000
   

2. Team members install:

   pip install langprotect-mcp-gateway
   # Configure mcp.json with credentials
   # Restart IDE
   

3. Monitor dashboard: See all team activity in real-time
