hs-sql-agent

Connect MCP-compatible AI clients to relational databases with server-enforced access, SQL safeguards, human-approved DML, and an operational Admin Panel.

hs-sql-agent supports SQLite, PostgreSQL, MySQL, SQL Server, Oracle, and Firebird as user databases.

What it provides

• schema discovery and governed SQL queries;
• human MCP Elicitation before DML is committed;
• database-, table-, and tool-scoped MCP keys;
• parameterized custom SQL tools;
• runtime row, timeout, DML, quota, and concurrency safeguards;
• structured audit history;
• SQLite/Memory single-instance and PostgreSQL/Redis distributed deployment options.
