Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Checks whether it runs in a sandbox mcp_server/ctf_advisor.py:60, lib/common.sh:1673
            "If Docker: check /.dockerenv, env vars, /etc/hosts for internal services",
Builds a file path from a variable .claude/skills/zeroize-audit/tools/generate_poc.py:1225
        poc_path = os.path.join(out_dir, filename)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
