WHAT IT DOES

What query_sqlite does on MCP Tabular Data Analysis Server

AI agents invoke query_sqlite to trigger actions in MCP Tabular Data Analysis Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why query_sqlite needs a policy

The tool name implies executing SQL queries against a SQLite database. Depending on what SQL is permitted, this could range from Read to Destructive (e.g., DROP, DELETE). Since the description is empty, we cannot confirm read-only restrictions. SQL execution tools are classified as Execute at minimum, and the blast radius is high because arbitrary SQL could modify or destroy data.

From the tool's definition Tool name 'query_sqlite' on a server that handles SQLite databases; description is empty and uninformative.
