workflow_reset · QueryNest MCP: Risk & Policy

WHAT IT DOES

What workflow_reset does on QueryNest

AI agents use workflow_reset to create or update resources in QueryNest — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your QueryNest environment.

WHY IT NEEDS A POLICY

Why workflow_reset needs a policy

This tool resets the workflow state, clearing progress and data to start fresh. While it clears data, this appears to be session/workflow state data rather than persistent database records, making it more of a Write (state modification) than Destructive. However, it does irreversibly clear progress, so severity is medium.

From the tool's definition 重置查询工作流，清除所有进度和数据，重新开始 (Reset query workflow, clear all progress and data, restart)

Verdict

workflow_reset Rate-limited

workflow_reset stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
