AI agents may call modify_subscriber_status to permanently remove or destroy resources in Carrier MCP: Give Your AI Agent Global Connectivity. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call modify_subscriber_status in a loop, permanently destroying resources in Carrier MCP: Give Your AI Agent Global Connectivity. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access modify_subscriber_status gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Use this to change the OCS lifecycle status of a subscriber. Common transitions: ACTIVE → SUSPENDED (pause without losing packages), SUSPENDED → ACTIVE (reactivate), ACTIVE/SUSPENDED → TERMINATED (irreversible). WARNING: TERMINATED status is permanent — the subscriber record cannot be reactivated. Params: iccid (subscriber identifier), status (new status string, e.g. 'ACTIVE', 'SUSPENDED', 'TERMINATED'). Returns: updated subscriber record with the new status. Do NOT use this to disable the SIM card at the network level — use change_sim_status for that. Always call get_subscriber first to confirm current status before modifying.. It is categorised as a Destructive tool in the Carrier MCP: Give Your AI Agent Global Connectivity MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Carrier MCP: Give Your AI Agent Global Connectivity MCP server in PolicyLayer and add a rule for modify_subscriber_status: 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 Carrier MCP: Give Your AI Agent Global Connectivity. Nothing to install.
modify_subscriber_status is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the modify_subscriber_status 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.
Set action: deny in the PolicyLayer policy for modify_subscriber_status. 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.
modify_subscriber_status is provided by the Carrier MCP: Give Your AI Agent Global Connectivity MCP server (carrier/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
