WHAT IT DOES

What list_active_queries does on Mcpg

AI agents call list_active_queries to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_active_queries is rated Low

This tool retrieves or lists active queries from the database, which is a non-destructive, informational operation. There are no side effects—it simply observes the current state of query execution. The empty description prevents higher confidence, but the name unambiguously indicates a read-only operation. Severity is low because listing active queries poses minimal risk if misused by an AI agent.

From the tool's definition Tool name 'list_active_queries' indicates retrieval of currently executing queries without modification. The verb 'list' is a read operation that queries database state.
