Verdicts

Gemini CLI

Apache-2.0, with 16 stable releases since 3 July and documented headless output. Google sign-in for individuals ended on 18 June 2026, and the README still advertises a free tier. Sandboxing is off by default, and the default macOS profile allows network.

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

Gemini CLI

  1. Set GEMINI_TRUST_WORKSPACE to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own
  2. Turn on the sandbox with -s or tools.sandbox, and pick a proxied Seatbelt profile on macOS to cut network
  3. Set privacy.usageStatisticsEnabled to false to stop usage statistics
  4. Since 0.63.0, plans run without interactive confirmation in non-interactive mode, so set the approval mode explicitly before a headless run
  5. Authenticate with a paid Gemini API key or Vertex credentials. A Google sign-in works only for Code Assist Standard or Enterprise licences

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
