Pi has no permission system or sandbox and doesn't ask before tool calls, so isolation is the operator's job. Version 1.4.0 is dated 21 October 2026.\n\n**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.\n\n## Before you call either\n\n### Pi\n\n1. Run Pi inside a container or VM for unattended work. It has no sandbox and doesn't ask before running shell commands\n2. Use `pi --mode json` and wait for `agent_settled`. A failed response doesn't set a nonzero exit code in JSON mode\n3. Split the JSONL stream on LF only. Node's `readline` also splits on U+2028 and U+2029, which are valid inside JSON strings\n4. Pass `--no-approve` or `--approve` in scripts to make the project trust decision explicit\n5. Set `PI_TELEMETRY=0` and `PI_SKIP_VERSION_CHECK=1`, or `PI_OFFLINE=1`, to stop the default requests to pi.dev\n\n### Vibe-Trading\n\n1. Run 0.1.7 or later. Earlier versions carry three published advisories, including unauthenticated API access with an RCE chain\n2. Set `API_AUTH_KEY` before exposing `vibe-trading serve` beyond localhost, and send it as `Authorization: Bearer \u003ckey\u003e`\n3. Set `VIBE_TRADING_ALLOWED_RUN_ROOTS` in the MCP client's `env` block; a shell `export` does not reach the spawned server\n4. Use `vibe-trading run -p \"...\" --json` for headless runs, and add `--enable-shell-tools` to `vibe-trading-mcp` only when shell access is needed\n5. Treat text from `read_url`, `web_search` and `read_document` as untrusted; `security_warnings` flags patterns but does not remove them\n\n## Questions\n\n### Which is better for AI agents, Pi or Vibe-Trading?\n\nPi scores 68.4 (B) on agent readiness against Vibe-Trading's 62.2 (B), and leads in 5 of 7 scored categories. Vibe-Trading leads on security \u0026 auth.\n\n### Are Pi and Vibe-Trading open source?\n\nYes. Pi is open source (MIT).
