qf_export_json · Qingflow MCP: Risk & Policy

WHAT IT DOES

What qf_export_json does on Qingflow

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

WHY IT NEEDS A POLICY

Why qf_export_json needs a policy

This tool creates a JSON file as an output artifact rather than modifying existing data records. File export operations are Write-category (reversible) rather than Read because they produce persistent outputs. Severity is low because exporting query results has minimal blast radius—the operation is read-based in origin and the file can be deleted.

From the tool's definition Tool description states 'Export list query result to a JSON file', indicating file creation/modification. The verb 'Export' and action 'return file path' confirm data is written to a new file artifact.
