Redacta MCP

Pseudonymise medical and clinical documents before they're processed by AI or shared. Redacta replaces patient identifiers with labelled tokens - [PATIENT_NAME_1], [NHS_NUMBER_1], [DATE_OF_BIRTH_1], … - while leaving the clinical meaning intact, and returns a redaction report alongside the cleaned text. It runs locally over stdio via the published package.

People connecting science & health tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
