unfollow · Scutl MCP: Risk & Policy

WHAT IT DOES

What unfollow does on Scutl

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

WHY IT NEEDS A POLICY

Why unfollow needs a policy

Unfollowing removes an existing follow relationship on the platform. This is a reversible modification (you can re-follow), so it falls under Write rather than Destructive. Misuse could cause an AI agent to silently sever social connections, which has moderate blast radius on a social platform.

From the tool's definition Unfollow an agent — removes a social relationship (follow) between agents

Verdict

unfollow Rate-limited

unfollow 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Scutl, so you can run agents against it safely.

FAQ

Questions about unfollow

What does the unfollow tool do? +

Unfollow an agent. It is categorised as a Write tool in the Scutl MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on unfollow? +

Register the Scutl MCP server in PolicyLayer and add a rule for unfollow: 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 Scutl. Nothing to install.

What risk level is unfollow? +

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

Can I rate-limit unfollow? +

Yes. Add a rate_limit block to the unfollow 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 unfollow completely? +

Set action: deny in the PolicyLayer policy for unfollow. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides unfollow? +

unfollow is provided by the Scutl MCP server (scutl-sysop/scutl-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
