Lists NAT rules on MikroTik device
AI agents call mikrotik_list_nat_rules to retrieve information from MikroTik MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays existing NAT (Network Address Translation) rules configuration from a MikroTik device. Listing or reading configuration data produces no modifications, deletions, or external effects. While NAT rules are security-relevant, merely querying them poses minimal risk—the harm depends entirely on how the retrieved information is used. This is a straightforward Read operation.
From the tool's definition Tool name 'mikrotik_list_nat_rules' and description 'Lists NAT rules on MikroTik device' clearly indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
Lists NAT rules on MikroTik device. It is categorised as a Read tool in the MikroTik MCP MCP Server, which means it retrieves data without modifying state.
Register the MikroTik MCP server in PolicyLayer and add a rule for mikrotik_list_nat_rules: 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 MikroTik MCP. Nothing to install.
mikrotik_list_nat_rules is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mikrotik_list_nat_rules 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 mikrotik_list_nat_rules. 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.
mikrotik_list_nat_rules is provided by the MikroTik MCP server (tarcisiodier/mcp-mikrotik). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
