WHAT IT DOES

What test_now_assist_skill does on ServiceNow MCP Server

AI agents invoke test_now_assist_skill to trigger actions in ServiceNow MCP Server. 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.

RISK

Why test_now_assist_skill is rated High

The tool runs/triggers an AI skill (Now Assist) with test data, which constitutes execution of an external operation. While described as a 'test' invocation, it still actively executes the skill and its effects depend on the skill being invoked. This is not purely read-only and falls under Execute. Severity is medium since it's gated by NOW_ASSIST_ENABLED and framed as testing, limiting blast radius somewhat.

From the tool's definition "Invoke a Now Assist skill with test input to verify behavior" — actively invokes/executes a skill with provided input
