x_unfollow_user · X MCP: Risk & Policy

WHAT IT DOES

What x_unfollow_user does on X

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

WHY IT NEEDS A POLICY

Why x_unfollow_user needs a policy

Unfollowing a user modifies a social relationship (removes a follow connection), which is a reversible write action. It does not delete content or data permanently — the user can be re-followed. Misuse could damage social relationships or be used for coordinated manipulation, hence medium severity.

x_unfollow_user Rate-limited

x_unfollow_user 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.
