workflows_featured_remove · Slack MCP: Risk & Policy

WHAT IT DOES

What workflows_featured_remove does on Slack

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

WHY IT NEEDS A POLICY

Why workflows_featured_remove needs a policy

Removing featured workflows from a channel modifies the channel's configuration (unfeaturing workflows), but does not permanently delete any data. The workflows still exist and can be re-featured, making this a reversible Write operation rather than Destructive.

From the tool's definition 'Remove featured workflows from a channel' — removes a configuration/association but does not delete the workflow itself; reversible by re-adding.
