# mcp-sql-guard

> Use this tool when you need to secure and validate SQL queries to prevent unauthorized data access and modifications. It solves problems related to data security and compliance by ensuring queries are read-only, limited, and masked according to user roles. The tool takes SQL queries as input and outputs validated and masked queries, along with a tamper-evident audit log, making it ideal for use cases requiring robust data protection and offline operation.
