clear_scope · Zencontrol Cloud MCP: Risk & Policy

WHAT IT DOES

What clear_scope does on Zencontrol Cloud

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

WHY IT NEEDS A POLICY

Why clear_scope needs a policy

This tool removes a scope constraint, which is a configuration change that alters the operational boundary of the system. It modifies system state (reversibly, since the scope could presumably be re-set), making it a Write operation.

From the tool's definition 'Remove the operational scope constraint' - this clears/removes a configuration setting

Verdict

clear_scope Rate-limited

clear_scope 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 Zencontrol Cloud, so you can run agents against it safely.

FAQ

Questions about clear_scope

What does the clear_scope tool do? +

Remove the operational scope constraint. It is categorised as a Write tool in the Zencontrol Cloud MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on clear_scope? +

Register the Zencontrol Cloud MCP server in PolicyLayer and add a rule for clear_scope: 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 Zencontrol Cloud. Nothing to install.

What risk level is clear_scope? +

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

Can I rate-limit clear_scope? +

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

Set action: deny in the PolicyLayer policy for clear_scope. 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 clear_scope? +

clear_scope is provided by the Zencontrol Cloud MCP server (owretch/zencontrol-cloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
