PII Redaction on Tool Responses
When an MCP tool returns data containing PII, SecuriX redacts it before the LLM processes it. Customer data never reaches external AI models in raw form.
Key Metric Highlight
Raw PII tokens sent to external LLM providers after redaction
// response-redaction.json (example redacted tool response)
{
"tool": "gmail.get_message",
"original_content_length": 847,
"redacted_content": "Hi, your order is confirmed. Please call us at [PHONE_REDACTED] or email [EMAIL_REDACTED]. Your card ending [CC_LAST4_REDACTED] was charged $129.00.",
"classifiers_triggered": ["PHONE_NUMBER", "CUSTOMER_EMAIL", "CREDIT_CARD"],
"redaction_count": 3,
"audit_event_id": "evt_4c8f2a71b"
}The Operational Battleground
Confronting friction points with deterministic platform security layers.
The Danger of Unchecked AI
MCP tools often return data that contains PII — a Gmail thread with a customer's credit card details, a Drive document with employee SSNs, a CRM record with phone numbers. If this data reaches the LLM, it reaches OpenAI or Anthropic's servers.
Governed, Hardened, & Compliant
SecuriX intercepts every MCP tool response and applies the DLP redaction engine before passing it to the LLM. Customer emails, phone numbers, and credit card numbers in tool responses are masked automatically — the LLM can still answer the user's question, but never processes raw PII.
Platform Deep Dive
Engineered from the ground up for strict isolation, low latency, and zero friction.
Response-Layer DLP
The same DLP classifiers that scan outbound prompts also scan inbound tool responses before the LLM processes them.
Semantic Redaction
Redacted tokens are replaced with semantic placeholders ([PHONE_REDACTED]) so the LLM can still form a coherent response.
De-masking for Authorized Roles
Authorized admin roles can view de-masked content in the audit log. Regular employees only ever see redacted values.
PII Redaction Audit Events
Every redaction generates an audit event: tool name, classifier triggered, user identity, and timestamp.
How It Works Under the Hood
DLP classifiers run on every tool response before the LLM sees the data
Credit cards, phone numbers, and customer emails in tool outputs are masked
LLM can reference '[PHONE REDACTED]' in its response without seeing the actual number
Every redaction is logged: which tool, which classifier matched, which user triggered it
Enterprise Compliance & Alignment
SecuriX policies align directly with top-tier verification structures, ensuring frictionless authorization for your infosec clearance review.
