reconnect_database · Qtz Iris MCP: Risk & Policy

WHAT IT DOES

What reconnect_database does on Qtz Iris

AI agents invoke reconnect_database to trigger actions in Qtz Iris. 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 reconnect_database needs a policy

This tool triggers an external operation — re-establishing a database connection — which has side effects beyond simple data retrieval. It does not read, write, or delete data, but it executes a connection lifecycle operation that could affect ongoing sessions and access states. Misuse could disrupt active queries or reset transaction contexts.
