List PCAP files available for analysis. Shows two categories: (1) locally synced PCAPs ready for analysis with file sizes and sync timestamps, and (2) PCAPs available in the GitHub repo that have not been synced yet.

AI agents call wireshark_list_pcaps to retrieve information from Wireshark MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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.
Attacks that exploit this kind of access
List PCAP files available for analysis. Shows two categories: (1) locally synced PCAPs ready for analysis with file sizes and sync timestamps, and (2) PCAPs available in the GitHub repo that have not been synced yet. Uses GitHub credentials from MCP headers (X-GitHub-Username, X-GitHub-PAT, X-GitHub-Repo, X-GitHub-Path, X-GitHub-Branch). No parameters required. It is categorised as a Read tool in the Wireshark MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wireshark MCP Server MCP server in PolicyLayer and add a rule for wireshark_list_pcaps: 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 Wireshark MCP Server. Nothing to install.
wireshark_list_pcaps is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the wireshark_list_pcaps 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 wireshark_list_pcaps. 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.
wireshark_list_pcaps is provided by the Wireshark MCP Server MCP server (presidio-federal/wireshark-mcp-container). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
