PII Redaction Deterministic Scrubber MCP Connector for Claude

The PII Redaction Deterministic Scrubber provides a high-precision pipeline for identifying and masking Personally Identifiable Information (PII) within unstructured text. Unlike probabilistic models, this server utilizes strict regular expression patterns combined with algorithmic checksum validators, such as the Luhn algorithm for credit card verification and ABA routing number validation for financial identifiers. The redact_pii tool processes input strings to identify sensitive entities including Social Security Numbers (SSN), email addresses, telephone numbers, and IBANs. For every execution, the engine returns a structured result containing the redacted text, a precise count of each PII type detected, and the exact character offsets for every identified match, enabling downstream systems to audit redaction coverage without exposing sensitive data.
