snow_fluent_install · Serac MCP: Risk & Policy

WHAT IT DOES

What snow_fluent_install does on Serac

AI agents invoke snow_fluent_install to trigger actions in Serac. 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 snow_fluent_install needs a policy

This tool executes a deployment operation ('now-sdk install') against a live ServiceNow instance, triggering an external operation that installs/deploys code. It runs a command with real side effects on a connected instance, making it Execute category. The blast radius is high because deploying incorrect or malicious code to a production ServiceNow instance could disrupt enterprise workflows.
