Removes an SSH key
AI agents call mikrotik_remove_user_ssh_key to permanently remove resources in MikroTik MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing an SSH key is a destructive action that cannot be undone—once deleted, the key is permanently removed from the system and cannot be recovered without manual re-addition. This meets the definition of Destructive (irreversibly deletes data).
From the tool's definition Tool name explicitly states 'remove' and description confirms 'Removes an SSH key'. This is an irreversible deletion of authentication credentials.
Attacks that exploit this kind of access
Removes an SSH key. It is categorised as a Destructive tool in the MikroTik MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MikroTik MCP server in PolicyLayer and add a rule for mikrotik_remove_user_ssh_key: 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_remove_user_ssh_key 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 mikrotik_remove_user_ssh_key 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_remove_user_ssh_key. 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_remove_user_ssh_key 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.
