unfollowList · Xdevplatform/x MCP: Risk & Policy

WHAT IT DOES

What unfollowList does on Xdevplatform/xmcp

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

WHY IT NEEDS A POLICY

Why unfollowList needs a policy

Unfollowing a list modifies the user's subscription/follow state but is reversible (the user can re-follow the list). No data is permanently deleted, making this a Write rather than Destructive action. Blast radius is low as it only affects the authenticated user's timeline preferences.

Verdict

unfollowList Rate-limited

unfollowList 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.

Questions about unfollowList

What does the unfollowList tool do? +

Register the Xdevplatform/x MCP server in PolicyLayer and add a rule for unfollowList: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Xdevplatform/xmcp. Nothing to install.

What risk level is unfollowList? +

unfollowList is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit unfollowList? +

Yes. Add a rate_limit block to the unfollowList rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block unfollowList completely? +
