A2db

A2db is an open-source Model Context Protocol (MCP) server designed to give AI agents fast, secure, read-only access to multiple SQL databases (PostgreSQL, MySQL, SQLite, Oracle, SQL Server) with batch query support, structured outputs, and enforced read-only security at the SQL AST level. Built for agent integration (Claude, MCP clients), rapid local setup, and automation, it enables agents to run multiple queries per call and receive clean, token-efficient results—ideal for developers building agent-powered data workflows or secure database access tools.
