create_workflow · Automator MCP: Risk & Policy

WHAT IT DOES

What create_workflow does on Automator

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

WHY IT NEEDS A POLICY

Why create_workflow needs a policy

An AI agent can call create_workflow faster than any human can review — one bad instruction and it creates or modifies resources in Automator by the hundred, each call as confident as the last.

Verdict

create_workflow Rate-limited

create_workflow 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.
