suggest_sql · Données Québec MCP: Risk & Policy

WHAT IT DOES

What suggest_sql does on Données Québec MCP

AI agents invoke suggest_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 suggest_sql needs a policy

The server description explicitly mentions SQL queries as a capability. A tool named 'suggest_sql' likely generates or executes SQL queries. Given the sibling tool 'find_and_query' also exists, this tool may 'suggest' SQL rather than execute it, which would be Read/Write, but could also execute the suggested SQL. With an empty description, confidence is low.

From the tool's definition Tool name 'suggest_sql' on a server that supports 'SQL queries' per server description; description is empty/uninformative.
