a2db MCP

a2db provides safe, read-only database access for AI agents via an MCP server. It supports batch queries across multiple databases (PostgreSQL, SQLite, MySQL, Oracle, SQL Server) using pre-configured connections and SQLGlot for AST parsing to enforce read-only constraints. It returns structured JSON envelopes with compact TSV data.
