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 lib/common.sh:1501, mcp_server/ctf_advisor.py:55

    if [[ -f /.dockerenv ]] || [[ -f /.containerenv ]] \

Runs an external command .claude/skills/constant-time-analysis/ct_analyzer/analyzer.py:455, .claude/skills/constant-time-analysis/ct_analyzer/script_analyzers.py:571, .claude/skills/zeroize-audit/tools/generate_poc.py:103 и ещё 1

            subprocess.run(

Builds a file path from a variable .claude/skills/zeroize-audit/tools/generate_poc.py:1225

        poc_path = os.path.join(out_dir, filename)

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.
