Lists firewall filter rules on MikroTik device
AI agents call mikrotik_list_filter_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 firewall filter rules from a MikroTik device without creating, modifying, or deleting any configuration. While the output could be network-sensitive information, the operation itself is a read-only query with no side effects or blast radius from misuse by an AI agent—it cannot alter the device state or network behavior.
From the tool's definition Tool name contains 'list' and description explicitly states 'Lists firewall filter rules'. The verb 'list' indicates data retrieval with no modification.
Attacks that exploit this kind of access
Lists firewall filter 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_filter_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_filter_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_filter_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_filter_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_filter_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.
