reconng_run · Kali Linux MCP Server MCP: Risk & Policy

WHAT IT DOES

What reconng_run does on Kali Linux MCP Server

AI agents invoke reconng_run to trigger actions in Kali Linux MCP Server. 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 reconng_run needs a policy

This tool executes an external reconnaissance/OSINT framework (Recon-ng) whose effects depend entirely on which modules and targets the AI provides as arguments. It is not a simple read operation—it performs active reconnaissance that can trigger external requests, generate network traffic, and return sensitive information about targets.

From the tool's definition Tool name 'reconng_run' indicates execution of Recon-ng, a reconnaissance and OSINT framework. The server description explicitly mentions 'OSINT capabilities' and lists sibling tools like 'amass_scan' and 'arping_scan' that are scanning/discovery tools.

Verdict

reconng_run Rate-limited

reconng_run 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.

What risk level is reconng_run? +

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

Can I rate-limit reconng_run? +

Yes. Add a rate_limit block to the reconng_run 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.
