Redact Pii

Redact PII from text

Use the kynth_redact MCP tool. It detects and strips names, emails, phone numbers, SSNs, card numbers, and PHI from text.

Parameters

• text (required), the text to redact
• types (optional), an array of entity type names to redact. Omit it to redact everything detected. Pass it only when the user wants some categories kept, for example redact SSNs and cards but keep names.
• placeholder (optional), the replacement token. Omit for the default.

Workflow

1. If the sensitive text is in a file, read it and pass the contents as text. For a PDF or an image, extract the text first with kynth_parse, then redact the result.
2. Call kynth_redact with the text. Default to full redaction, with no types, unless the user scoped it.
3. Return the redacted text. Check it against anything the user specifically flagged; if a flagged item survived, run a second pass with an explicit types entry for it.
4. Never echo the original unredacted values back in your summary. The point is that they stop propagating.
