query_resource_sql · Données Québec MCP: Risk & Policy

WHAT IT DOES

What query_resource_sql does on Données Québec MCP

AI agents invoke query_resource_sql to trigger actions in Données Québec MCP. 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_resource_sql needs a policy

The name contains 'sql' suggesting it runs SQL queries against a data resource. SQL execution can have wide-ranging effects depending on permissions — potentially reading, writing, or even destructive operations (DROP, DELETE). With an empty description, we cannot confirm read-only constraints, so we escalate to Execute. Severity is high given the blast radius of arbitrary SQL execution if misused.

From the tool's definition Tool name 'query_resource_sql' strongly implies execution of SQL queries; description is empty and provides no further detail.
