PII & Secret Redactor Overview

The PII & Secret Redactor MCP server detects PII and credentials in text before it is sent to an LLM, log, or ticket. It verifies supported financial identifiers with checksums and returns masked findings without exposing complete values. Redaction can use stable placeholders, masks, salted hashes, or removal, while a retained mapping enables restoration after the model responds. Use it when an MCP client needs to reduce sensitive-data exposure, while recognizing that pattern-based detection is not a compliance guarantee.

Primary Use Cases for PII & Secret Redactor:

Redact customer data before sending prompts to an LLM
Remove credentials from logs and support tickets
Restore original values in generated responses
Inspect detector coverage before processing sensitive text
