@openclueo/express-clueobots

Express.js middleware for ClueoBots AI Security - One line of code, full protection

Protect your Express.js applications from AI security threats with just one line of code. Automatically scans incoming requests for prompt injection, jailbreaking, data exfiltration, and other LLM-based attacks.

🚀 Quick Start

Installation

npm install @openclueo/express-clueobots

Basic Usage

import express from 'express'
import { clueobots } from '@openclueo/express-clueobots'

const app = express()
app.use(express.json())

// ONE LINE = FULL AI SECURITY PROTECTION
app.use(clueobots({ apiKey: 'your-clueobots-api-key' }))

// All your routes are now automatically protected
app.post('/api/chat', (req, res) => {
  // req.body is already scanned for threats
  // Malicious prompts are blocked before reaching here
  res.json({ message: 'Safe to proceed with AI processing!' })
})

app.listen(3000)

      details: threat
    })

💡 Usage Examples

Protect Specific Routes

import { clueobots } from '@openclueo/express-clueobots'

// Only protect AI-related endpoints
app.use('/api/chat', clueobots())
app.use('/api/generate', clueobots())
app.use('/api/ai', clueobots())

// Other routes are unaffected
app.use('/api/users', regularMiddleware())

Custom Threat Handling

app.use(clueobots({
  apiKey: process.env.CLUEOBOTS_API_KEY,
  blockThreshold: 'high', // Only block high/critical threats

  onThreat: (threat, req, res) => {
    // Log threat for analysis
    console.log('Security Alert:', {
      threatType: threat.threatType,
      riskLevel: threat.riskLevel,
      userAgent: req.get('user-agent'),
      ip: req.ip,
      timestamp: threat.timestamp
    })

    // Custom response
    res.status(403).json({
      error: 'Request blocked for security reasons',
      message: 'Please rephrase your request and try again',
      supportId: threat.scanId
    })
  }
}))

Selective Protection

app.use(clueobots({
  paths: ['/api/chat', '/api/generate', '/api/completion'],
  excludePaths: ['/api/health', '/api/metrics'],
  skipContentTypes: ['image', 'application/pdf'],
  maxBodySize: 1024 * 1024, // 1MB max scan size
}))

Development Mode

app.use(clueobots({
  debug: true, // Enable detailed logging
  blockRequests: false, // Log threats but don't block (monitoring mode)

  onThreat: (threat, req, res) => {
    console.log('🚨 THREAT DETECTED (dev mode):', threat)
    // Continue processing in development
  }
}))

🔍 Request Enhancement

The middleware enhances your Express requests with threat information:

interface RequestWithClueoBots extends Request {
  clueobots?: {
    scanned: boolean
    threat?: ThreatInfo
    scanTime: number
  }
}

app.post('/api/chat', (req: RequestWithClueoBots, res) => {
  if (req.clueobots?.threat) {
    // Handle threat detected but not blocked
    console.log(`Low-level threat: ${req.clueobots.threat.threatType}`)
  }

  console.log(`Scan took: ${req.clueobots?.scanTime}ms`)

  // Your business logic here
})

🎪 Real-world Examples

ChatGPT Clone Protection

import express from 'express'
import { clueobots } from '@openclueo/express-clueobots'
import OpenAI from 'openai'

const app = express()
const openai = new OpenAI()

// Protect all chat endpoints
app.use('/api/chat', clueobots({
  blockThreshold: 'medium',
  onThreat: (threat, req, res) => {
    res.json({
      error: 'I cannot process that request for security reasons.',
      suggestion: 'Please rephrase your message in a different way.'
    })
  }
}))

app.post('/api/chat/completions', async (req, res) => {
  // Request is already secured by ClueoBots
  const completion = await openai.chat.completions.create({
    model: 'gpt-4',
    messages: req.body.messages
  })

  res.json(completion)
})

Content Generation API

app.use('/api/generate', clueobots({
  blockThreshold: 'high', // More permissive for creative content

  onThreat: (threat, req, res) => {
    if (threat.riskLevel === 'critical') {
      // Block critical threats
      res.status(400).json({
        error: 'Content generation request blocked',
        reason: 'Security policy violation'
      })
    } else {
      // Log but allow medium/high threats for creative content
      console.log('Creative content threat logged:', threat.threatType)
    }
  }
}))

app.post('/api/generate/story', async (req, res) => {
  // Generate creative content safely
  const story = await generateStory(req.body.prompt)
  res.json({ story })
})

📊 Performance & Analytics

Monitoring

app.use(clueobots({
  onThreat: (threat, req, res) => {
    // Send to your analytics service
    analytics.track('threat_detected', {
      threatType: threat.threatType,
      riskLevel: threat.riskLevel,
      confidence: threat.confidence,
      endpoint: req.path,
      userAgent: req.get('user-agent')
    })
  }
}))

Health Checks

app.get('/api/security/health', (req, res) => {
  // This endpoint is automatically excluded
  res.json({
    status: 'healthy',
    clueobots: 'active'
  })
})

🚨 Error Handling

Graceful Degradation

app.use(clueobots({
  onError: (error, req, res) => {
    console.error('ClueoBots service error:', error)

    // Log to monitoring service
    monitoring.error('clueobots_error', error)

    // Fail open - continue processing
    // Your app stays available even if ClueoBots is down
  }
}))

Circuit Breaker Pattern

let errorCount = 0
const ERROR_THRESHOLD = 5

app.use(clueobots({
  onError: (error, req, res) => {
    errorCount++

    if (errorCount > ERROR_THRESHOLD) {
      // Temporarily disable ClueoBots to prevent cascading failures
      console.log('ClueoBots circuit breaker activated')
      // Implement your circuit breaker logic
    }
  }
}))
