AI agents use assign_recurring_package to create or modify resources in Carrier MCP: Give Your AI Agent Global Connectivity. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call assign_recurring_package repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Carrier MCP: Give Your AI Agent Global Connectivity.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access assign_recurring_package gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Use this to assign an auto-renewing prepaid package to a subscriber. The package renews automatically based on the template's periodicity settings, reducing churn from manual renewal. Params: iccid (subscriber identifier), packageTemplateId (integer from list_package_templates — must be a template configured with recurring/periodicity settings). Returns: created recurring package record with packageId and renewal schedule. Do NOT use this for one-time packages — use assign_package instead. To pause or cancel auto-renewal without deleting the package, use stop_resume_recurring_package.. It is categorised as a Write tool in the Carrier MCP: Give Your AI Agent Global Connectivity MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Carrier MCP: Give Your AI Agent Global Connectivity MCP server in PolicyLayer and add a rule for assign_recurring_package: 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.
assign_recurring_package is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the assign_recurring_package 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 assign_recurring_package. 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.
assign_recurring_package 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.
