## Which one, for what

### Gemini CLI (B)

Good for: Teams with a paid Gemini API key, Vertex AI credentials or existing Code Assist Standard or Enterprise licences that want an open-source harness with documented headless output.

Ahead on:
- Reliability, 71 against 63
- Schema & documentation, 93 against 72
- Agent ergonomics, 78 against 67
- Maintenance & community, 88 against 82
- Transparency & trust, 89 against 47

Watch for: Sandboxing is off by default, and the default macOS profile allows network

### Vibe-Trading (B)

Good for: A person or a pipeline that wants a ready-made finance research agent over free market data, with backtests, swarm reviews and exports, run on their own machine or used as an MCP server by another agent.

Ahead on:
- Payments & pricing, 60 against 20

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Free to start without a card

Watch for: Three advisories published 2 October 2026 cover 0.1.0 to 0.1.6, two critical, among them unauthenticated API access with an RCE chain

## 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
