query_database · Integrations MCP: Risk & Policy

WHAT IT DOES

What query_database does on Integrations MCP

AI agents invoke query_database to trigger actions in Integrations 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_database needs a policy

The name 'query_database' suggests executing database queries, which could range from read-only SELECT statements to destructive DROP/DELETE operations depending on arguments. Given the most-severe-applicable rule and the ambiguity of an empty description, Execute is chosen (potentially Destructive if arbitrary SQL is permitted). Severity is critical due to potential for data exfiltration or destruction.

From the tool's definition Tool name: 'query_database' — description is empty and uninformative.
