ssrf_detector · MCP Kali Pentest MCP: Risk & Policy

WHAT IT DOES

What ssrf_detector does on MCP Kali Pentest

AI agents invoke ssrf_detector to trigger actions in MCP Kali Pentest. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ssrf_detector needs a policy

SSRF detection tools work by sending specially crafted HTTP requests to a target server to cause it to make outbound connections, which constitutes active exploitation/probing behavior. This is an Execute-category action as it triggers external operations on target systems. The blast radius is high given the penetration testing context and potential for unintended side effects on scanned systems.

From the tool's definition Server-Side Request Forgery (SSRF) vulnerability detection — actively probes target servers by sending crafted requests to detect SSRF vulnerabilities, triggering external operations against target systems

Verdict

ssrf_detector Rate-limited

ssrf_detector stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about ssrf_detector

What does the ssrf_detector tool do? +

Server-Side Request Forgery (SSRF) vulnerability detection. It is categorised as a Execute tool in the MCP Kali Pentest MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on ssrf_detector? +

Register the MCP Kali Pentest MCP server in PolicyLayer and add a rule for ssrf_detector: 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 MCP Kali Pentest. Nothing to install.

What risk level is ssrf_detector? +

ssrf_detector is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit ssrf_detector? +

Yes. Add a rate_limit block to the ssrf_detector 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.

How do I block ssrf_detector completely? +

Set action: deny in the PolicyLayer policy for ssrf_detector. 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.

What MCP server provides ssrf_detector? +

ssrf_detector is provided by the MCP Kali Pentest MCP server (root1856/mcpkali). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
