WHAT IT DOES

What flow_create does on DevFlow MCP Server

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

WHY IT NEEDS A POLICY

Why flow_create needs a policy

This tool creates new records (flows/feature requests/bug reports/tasks) in a project management system, which is a reversible write operation. While it doesn't execute code or delete data, creating many flows could clutter the system, and improper use could generate noise or false workflows.

From the tool's definition Tool description states 'Create a new flow in a project' and 'Use this to create new feature requests, bug reports, or tasks.' The verb 'Create' and explicit mention of creating new items indicates data creation.
