Sentinel Tag

What It Does

Sentinel Tag scans every field in every row and classifies sensitive data according to regulatory frameworks: PII, PCI, and PHI. It uses pattern matching (regex for SSNs, credit card numbers), ML-based entity recognition (names, addresses), and contextual analysis to achieve high-accuracy classification.

Capabilities

• PII detection (names, emails, SSNs, addresses)
• PCI detection (card numbers, CVVs, expiry dates)
• PHI detection (medical record numbers, diagnoses)
• ML-based entity recognition
• Field-level sensitivity tagging
• Regulatory framework mapping
• Confidence scoring per field

Example

const result = await mcp.call('sentinel_tag_classify', {
  payload: sanitizedPayload,
  stream_uuid: streamUUID,
  frameworks: ['pii', 'pci', 'phi'],
});
// { "email": "PII:EMAIL", "card_number": "PCI:PAN" }
console.log(result.sensitivity_score); // 0.87
