Open source (khodossss)
MCP SQL privacy gateway that parses agent-written queries, traces outputs to protected base columns, regenerates read-only SQL and replaces declared personal values with stable local tokens. A signed-in human can resolve tokens locally; the model cannot.
Verified 2026-11-04 from repository README, threat model and benchmark summary. Supports PostgreSQL, MySQL, SQL Server, SQLite and DuckDB. Vendor-authored Nov. 3 run reports 0/2,894 hidden-value leaks under strict and permissive profiles, with 164/180 and 180/180 honest tasks answered respectively; compares 15 tools. MVP is explicitly not audited, has 0 stars/0 forks at discovery, and permissive mode intentionally exposes order/length/prefix/contains information subject to budgets, so independent security review is required.
