Permanently remove a file from the remote server. Use with caution.
AI agents call ftp_delete to permanently remove resources in Ftp — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data without possibility of recovery, fitting the Destructive category definition. While blast radius is limited to a single file per invocation (not Critical), it causes permanent data loss and justifies High severity due to enterprise FTP context where data integrity is critical.
From the tool's definition Tool description explicitly states 'Permanently remove a file from the remote server' and includes warning 'Use with caution.' The operation is irreversible deletion of data on a remote system.
Attacks that exploit this kind of access
Permanently remove a file from the remote server. Use with caution. It is categorised as a Destructive tool in the Ftp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ftp MCP server in PolicyLayer and add a rule for ftp_delete: 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 Ftp. Nothing to install.
ftp_delete 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 ftp_delete 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 ftp_delete. 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.
ftp_delete is provided by the Ftp MCP server (kynlos/ftp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
ftp_delete is one line of Ftp's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
