AI agents call wapiti_get_cookie to retrieve information from Pentester-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_cookie' function retrieves cookie data from web targets without modifying or deleting it. Despite the penetration testing context and the absence of a detailed description, the core action is data retrieval. However, severity is elevated to 'medium' rather than 'low' because cookies may contain sensitive authentication tokens or session identifiers; misuse could facilitate unauthorized access attempts.
From the tool's definition Tool name contains 'get_cookie' and is situated on a penetration testing server; the Wapiti tool is known to be a web vulnerability scanner that retrieves and analyzes HTTP cookies as part of reconnaissance and session analysis.

PolicyLayer is an MCP gateway — it sits between your AI agents and Pentester-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for wapiti_get_cookie:
{
"version": "1",
"default": "deny",
"tools": {
"wapiti_get_cookie": {}
}
}wapiti_get_cookie is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

wapiti_get_cookie. It is categorised as a Read tool in the Pentester-MCP MCP Server, which means it retrieves data without modifying state.
Register the Pentester- MCP server in PolicyLayer and add a rule for wapiti_get_cookie: 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 Pentester-MCP. Nothing to install.
wapiti_get_cookie 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 wapiti_get_cookie 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 wapiti_get_cookie. 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.
wapiti_get_cookie is provided by the Pentester- MCP server (halilkirazkaya/pentester-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pentester-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
