QueryShield MCP

QueryShield is a secure SQL proxy and named credential vault designed for AI agents. It translates natural language to SQL via Claude, validates queries at the AST level to ensure only SELECT statements are allowed, and applies per-agent row-level security. It executes queries against customer databases and logs attempts to an append-only audit table, ensuring agents never see connection strings.
