run_preset_test · Artillery MCP Server MCP: Risk & Policy

WHAT IT DOES

What run_preset_test does on Artillery MCP Server

AI agents invoke run_preset_test to trigger actions in Artillery 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.

WHY IT NEEDS A POLICY

Why run_preset_test needs a policy

This tool executes load tests (smoke, baseline, soak, spike) which are external operations with non-trivial side effects. While load tests are designed to be safe and reversible (unlike destructive operations), they can impact system performance, generate infrastructure costs, consume resources, and potentially interfere with other services or users.

From the tool's definition Tool description states 'Run a preset test type' which directly executes an external operation (load testing).
