delete_lines
AI agents call delete_lines to permanently remove resources in TermPipe MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool name 'delete_lines' combined with the server's file management capabilities strongly suggests this tool deletes lines from files. Line deletion is irreversible without backups, making it destructive. Although the description is empty, the name and context are clear enough to classify with high confidence.
From the tool's definition Tool name 'delete_lines' with empty description, paired with a server that provides 'direct terminal access to execute commands, manage files'. The name explicitly indicates irreversible deletion of file content.
Attacks that exploit this kind of access
delete_lines. It is categorised as a Destructive tool in the TermPipe MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TermPipe MCP server in PolicyLayer and add a rule for delete_lines: 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 TermPipe MCP. Nothing to install.
delete_lines 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 delete_lines 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 delete_lines. 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.
delete_lines is provided by the TermPipe MCP server (wbind-core/termpipe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
