WHAT IT DOES

What zip_list_files does on Nodebench

AI agents call zip_list_files to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why zip_list_files is rated Low

This tool performs a read-only operation that queries and retrieves the file listing from a ZIP archive. There is no data modification, deletion, execution of code, or external side effects. The deterministic and local nature further confirms it as a safe read operation with minimal blast radius if misused.

From the tool's definition Tool name and description indicate it 'List entries in a local ZIP file' with 'Deterministic, no network.' The verb 'list' and 'entries' confirm retrieval of information about ZIP file contents without modification or side effects.

RECOMMENDED RULE

The rule that runs zip_list_files safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For zip_list_files, this is the rule to start with:

zip_list_files Allowed

zip_list_files is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every zip_list_files call is checked against it from then on.
