Privacyscrubber MCP

CISO-Approved Zero-Trust PII & Secrets Redaction MCP Server for Cursor, Windsurf, and Claude Desktop. Locally scrubs PII, secrets, credentials, and custom regex rules from files and text contexts before they reach remote LLM providers to prevent API leaks and ensure HIPAA/SOC 2 compliance at the developer endpoint.

People who work with data security, masking methods and pii and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
