create_campaign · Flour Ads MCP: Risk & Policy

WHAT IT DOES

What create_campaign does on Flour Ads

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

WHY IT NEEDS A POLICY

Why create_campaign needs a policy

create_campaign creates new advertising campaigns, which is a reversible modification operation. Severity is high because misuse could commit significant marketing spend and create unwanted campaigns, but it's Write rather than Financial because the tool itself doesn't move money—budget updates are handled separately (update_budget).

From the tool's definition Tool name 'create_campaign' on ad management server that 'enables deploying campaigns' and 'managing budgets'. Description is empty, but context from server description makes the Write classification clear.
