# postgres-safe-mcp

> Use this tool when you need to securely interact with PostgreSQL databases while protecting sensitive user data. It solves the problem of inadvertently exposing personally identifiable information (PII) in query results by automatically detecting and obfuscating sensitive data using column-name heuristics and NLP analysis. The tool takes database queries as input and returns masked query results, allowing for selective unmasking under user control.
