WHAT IT DOES

What ctf_steghide does on Hercules MCP

AI agents invoke ctf_steghide to trigger actions in Hercules MCP. 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.

RISK

Why ctf_steghide is rated High

This tool runs steghide commands to extract hidden data from media files. While extraction itself doesn't destroy data, it executes external processes whose behavior depends on user-supplied arguments (target files). This is characteristic of Execute category tools.

From the tool's definition Tool exposes steghide, an offensive security tool for steganography analysis and extraction. Steghide can extract hidden data from image and audio files, which constitutes execution of external commands with side effects dependent on the files being analyzed.

RECOMMENDED RULE

The rule that runs ctf_steghide safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Hercules MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ctf_steghide, this is the rule to start with:

ctf_steghide Rate-limited

ctf_steghide 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.
