Verdicts

Cline

Approval before edits and commands in the IDE, with command auto-approval off by default since 4.0.0. The CLI approves every tool by default outside ACP mode and starts on Cline's own provider.

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

Cline

  1. Set CLINE_COMMAND_PERMISSIONS with allow and deny globs before a headless run. The CLI approves every tool by default
  2. Pick a provider with -P and a key, or run cline auth. The default provider needs a Cline sign-in
  3. Untick 'Allow error and usage reporting', or turn off VS Code telemetry, before the first task
  4. Pin the CLI version. 2.3.0 was a malicious publish
  5. Keep the hub on 127.0.0.1 or set ROOM_SECRET, and run 3.0.30 or later

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
