PII-Shield

PII-Shield is a security-focused tool that integrates with Claude via the Model Context Protocol (MCP) to automatically detect and anonymize personally identifiable information (PII) in text before it reaches the AI. It is designed for developers and enterprises handling sensitive user data who need to leverage AI assistants without risking privacy compliance violations. The project is interesting because it enables safe, real-time AI collaboration on confidential documents by stripping PII at the system level, rather than relying on user discretion or post-hoc redaction.
