AI agents call pcap_get_http to retrieve information from Windows Forensics 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 forensic analysis by extracting and parsing HTTP request data from packet capture files. It is purely a read operation that analyzes existing artifacts without side effects, modifying data, executing code, or deleting anything. The low severity reflects that misuse would only expose logged network traffic information already captured in the PCAP file, with no ability to modify systems or data.
From the tool's definition Tool name 'pcap_get_http' and description 'Extract HTTP requests from PCAP' indicate retrieval and parsing of packet capture data. The verb 'extract' and 'get' denote read-only data retrieval operations without modification or execution of external systems.
Documented attack patterns abuse exactly the kind of access pcap_get_http gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Windows Forensics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for pcap_get_http:
{
"version": "1",
"default": "deny",
"tools": {
"pcap_get_http": {}
}
}pcap_get_http is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Extract HTTP requests from PCAP. It is categorised as a Read tool in the Windows Forensics MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Windows Forensics MCP Server MCP server in PolicyLayer and add a rule for pcap_get_http: 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 Windows Forensics MCP Server. Nothing to install.
pcap_get_http 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 pcap_get_http 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 pcap_get_http. 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.
pcap_get_http is provided by the Windows Forensics MCP Server MCP server (x746b/winforensics-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Windows Forensics MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
