What wireshark_list_pcaps does on Wireshark MCP Server

Why wireshark_list_pcaps needs a policy

This tool performs a read-only query operation that enumerates available PCAP files and their metadata (file sizes, sync timestamps). It retrieves information about network packet capture files without creating, modifying, executing commands on, or deleting any data. The blast radius if misused is minimal—worst case an agent learns what files exist, which is non-sensitive filesystem enumeration.

From the tool's definition Tool description states it 'List[s] PCAP files available for analysis' and 'Shows two categories: (1) locally synced PCAPs... (2) PCAPs available in the GitHub repo'. The verb 'list' and 'shows' indicate data retrieval with no modification.
