Verdicts

Cursor CLI

Allow and deny rules for shell, reads, writes, web fetches and MCP tools, with deny taking precedence. No CLI changelog, and versions are dates.

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

Cursor CLI

  1. Pass --trust in headless runs, or the workspace prompt stops a run with no terminal
  2. Write deny rules in .cursor/cli.json before using --force. It runs any command they don't match
  3. Don't use --approve-mcps in repositories you didn't write. Two 2025 CLI advisories came through MCP
  4. Set CURSOR_API_KEY in CI. agent login opens a browser
  5. Record agent --version with each run. Versions are dates and there's no CLI changelog to compare against

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
