create_flow · Directus MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_flow does on Directus MCP Server

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

WHY IT NEEDS A POLICY

Why create_flow needs a policy

Creating an automation flow is a Write operation as it creates a new persistent record in Directus. However, automation flows can trigger external operations, execute code, or cause significant side effects when activated, making the severity high — a misconfigured or malicious flow could cause widespread damage across the system.

From the tool's definition "Create a new automation flow" — creates a new entity (flow) in the system

Verdict

create_flow Rate-limited

create_flow 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.
