The RAGE API module provides intelligent context enrichment for LibreChat conversations by integrating with Vectorize.io to retrieve relevant information from organizational knowledge bases stored in Qdrant vector databases.

• Seamless Integration: Transparent context enrichment without user intervention
• High Performance: Sub-500ms response times with 5-second timeout protection
• Fault Tolerance: Graceful degradation when external services are unavailable
• Zero Configuration: Works out-of-the-box with environment variables
• Enterprise Ready: JWT authentication and audit logging

• LibreChat instance running
• Vectorize.io account with API access
• Qdrant vector database configured
• JWT bearer token for authentication

The RAGE Interceptor is automatically loaded when environment variables are configured. No additional setup required.

Once configured, RAGE automatically enriches every conversation with relevant context:

1. User sends a message
2. RAGE intercepts the message
3. Retrieves relevant documents from vector database
4. Formats context for optimal LLM consumption
5. Enriched message is processed by LLM

• Average Response Time: <500ms
• Timeout Protection: 5 seconds maximum
• Concurrent Requests: 100+ simultaneous
• Memory Usage: <50MB per instance

RAGE is designed to fail gracefully:

• Network timeouts → Continue without context
• API errors → Log and proceed normally
• Authentication failures → Retry with exponential backoff
• Rate limiting → Intelligent throttling

Built-in logging and metrics collection:

• Response time percentiles
• Success/failure rates
• Context relevance scores
• Error categorization

# Instant disable/enable RAGE_ENABLED=false # Development mode with verbose logging RAGE_DEBUG=true

• JWT tokens stored in environment variables only
• HTTPS-only communication with external APIs
• Input sanitization and validation
• No sensitive data in logs
• Audit trail for all API calls

RAGE not working

• Check RAGE_ENABLED=true
• Verify all required environment variables
• Test JWT token validity

Slow responses

• Check network connectivity to Vectorize.io
• Monitor API response times
• Adjust RAGE_TIMEOUT if needed

Empty context

• Verify Qdrant database has indexed documents
• Check relevance score threshold
• Review search query formatting

Enable detailed logging:

RAGE_DEBUG=true

Test RAGE connectivity:

curl -H "Authorization: Bearer $RAGE_VECTORIZE_API_KEY" \ "$RAGE_VECTORIZE_URI/org/$RAGE_VECTORIZE_ORGANIZATION_ID/pipelines/$RAGE_VECTORIZE_PIPELINE_ID/health"

Test RAGE queries directly without LibreChat:

# Basic query test npm run rage:query "What is the company policy?" # JSON output format npm run rage:query "Employee handbook" --format json # Debug mode with verbose output  npm run rage:query "Benefits info" --debug --format verbose # Test with mock data (no API call required) npm run rage:query "test query" --mock

Available options:

• --format - Output format: json, pretty, verbose
• --debug - Enable debug mode with detailed request/response
• --mock - Use mock responses for testing
• --timeout <ms> - Request timeout in milliseconds
• --max-results <n> - Maximum results to return
• --help - Display help and usage examples

See Tools Documentation for complete usage guide.
