AI-Safe MCP Server for SQL

Giving an AI direct database access is one of those ideas that sounds useful immediately and dangerous a few seconds later. You want the model to inspect schema, understand relationships, run queries, and help with analysis. But you also do not want it to mutate data, run unrestricted SQL, or pull back massive result sets because a prompt was vague. That was the motivation behind ajan-sql. It is a small MCP server for SQL that gives AI clients schema-aware, read-only SQL access with a guard layer in front of query execution.
