xby-db

Giving an AI assistant direct database access is a risky proposition. Expose the raw connection and you open the door to injection attacks or accidental DROP statements; lock it down completely and you forfeit the very automation that makes LLM tooling useful. xby-db sits in the middle as a controlled gateway, turning AI-driven database access into something that is rule-bound, fully audited, and individually toggled.

The core capabilities map to the everyday database workflow. Use db_tables and db_describe_table to quickly enumerate schemas and inspect column types and nullability. Use db_execute with :param placeholder syntax to run SELECT queries, or INSERT / UPDATE / DELETE and DDL statements when those modes are enabled. Use db_explain to retrieve the optimizer plan and spot slow paths before they become production incidents. Every request is validated and written to an audit log, and the service supports SQLite, PostgreSQL, MySQL, and MariaDB out of the box.

This plugin is aimed at admins and developers building AI workflows inside DeepSeek Harness—people who want their assistant to generate reports, profile indexes, and make small data corrections on the fly, without ever handing a bare database credential to a language model. xby-db is the middle ground where intelligence meets guardrails.
