Advisory Marrow: the Marrow MCP server (pinned @getmarrow/mcp 3.9.107) and a short skill, with no hooks. Marrow sees an action only when the agent calls a marrow_* tool, so nothing is held or enforced.

getmarrow/plugins 1

Fast, free, first-pass security smell test. Point a tiny local LLM (antares-1b, a ~2GB Granite-4.0 fine-tune) at a folder to get cheap vulnerability leads across a codebase in seconds — before a deeper audit. A triage aid, NOT a substitute for Semgrep, CodeQL, or Bandit.
