AI agents call wireshark_extract_credentials 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.
Although this tool outputs sensitive credentials that could enable account compromise, its core function is passive information retrieval from static PCAP files. It scans, extracts, and returns data without modifying the PCAP, executing code, or triggering external operations.

Extract credentials from a locally synced PCAP file for security audits. Scans for HTTP Basic Auth, FTP, Telnet plaintext credentials, and Kerberos hashes. Returns plaintext credentials immediately usable and encrypted credentials with offline cracking commands. Sync the PCAP first using wireshark_sync_pcap. Required: pcap_name. 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_extract_credentials: 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_extract_credentials 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_extract_credentials 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_extract_credentials. 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_extract_credentials 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.
