Web Application Firewall detection
AI agents call wafw00f to retrieve information from PenTest MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
WAF detection is a read-only reconnaissance activity that queries target systems to identify security mechanisms. It retrieves information about deployed firewalls but does not create, modify, delete, or execute any operations. The tool has no side effects beyond information gathering, making it a Read category risk.
From the tool's definition Tool name 'wafw00f' and description 'Web Application Firewall detection' indicate passive reconnaissance that detects and identifies WAF technologies protecting web applications.
Attacks that exploit this kind of access
Web Application Firewall detection. It is categorised as a Read tool in the PenTest MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PenTest MCP Server MCP server in PolicyLayer and add a rule for wafw00f: 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 PenTest MCP Server. Nothing to install.
wafw00f 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 wafw00f 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 wafw00f. 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.
wafw00f is provided by the PenTest MCP Server MCP server (mohitsahoo/mcptoolforwebvulnerabilities-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
wafw00f is one line of PenTest MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
