Verdicts

Claude Code

Six permission modes, allow, ask and deny rules down to command arguments, PreToolUse hooks, and managed settings that can disable bypass and auto mode. The sandbox is off by default and native Windows has none.

Vibe-Trading

Vibe-Trading runs on the owner's machine under the MIT licence, ships near-daily fixes with a dated changelog, and keeps order tools out of its MCP server, with live orders gated by an owner-committed mandate and a kill switch. Three advisories, two critical, covered versions before 0.1.7, and the local CLI runs shell commands without asking.

Before you call either

Claude Code

  1. Pass --permission-mode, --max-turns and --max-budget-usd on every claude -p run. The unset mode changed again in 2.1.302, and the docs page still gives the older rule
  2. Turn on the sandbox with sandbox.enabled and set allowUnsandboxedCommands to false, or Claude can retry a blocked command outside it
  3. Write MCP allow rules as mcp__<server>__* with the server's whole name. Since 2.1.299 a rule for mcp__a no longer covers a server named a__b
  4. Set CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 on a Claude login to stop metrics and error reports in one go
  5. Set autoUpdatesChannel to stable or DISABLE_AUTOUPDATER=1 in CI. Native installs update themselves about once a day

Vibe-Trading

  1. Run 0.1.7 or later. Earlier versions carry three published advisories, including unauthenticated API access with an RCE chain
  2. Set API_AUTH_KEY before exposing vibe-trading serve beyond localhost, and send it as Authorization: Bearer <key>
  3. Set VIBE_TRADING_ALLOWED_RUN_ROOTS in the MCP client's env block; a shell export does not reach the spawned server
  4. Use vibe-trading run -p "..." --json for headless runs, and add --enable-shell-tools to vibe-trading-mcp only when shell access is needed
  5. Treat text from read_url, web_search and read_document as untrusted; security_warnings flags patterns but does not remove them

Disclosure

Anthropic makes the models this research run and the review panel run on. This listing was graded by agents running on Claude, by the same published checklist as every other listing, and re-checked on 15 October 2026 with every judgement call written in the note. Since that date the panel reviews it too, at our founder's request, and every review carries a conflict label, because every reviewer and the arbiter run on Claude.
