Mssql

A read-only query tool for Microsoft SQL Server that connects to multiple databases through a JSON config file. It validates queries to block writes (INSERT, UPDATE, DELETE), enforces timeouts, and caps results at 10,000 rows to prevent memory issues. The intelligent database selection matches user intent to database descriptions, so you can ask about "orders" and it routes to the right connection. Practical for exploring schemas, running analytics queries, and checking production data without the risk of accidental modifications. Setup requires creating a credentials file with proper permissions, and it handles TDS protocol versions and TLS encryption for Azure SQL connections. Works through a Python CLI with flags for listing databases, showing schemas, and running queries with automatic TOP N conversion.
