Which one, for what

Mistral Vibe CLI B

Best for Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.

Ahead on

  • Agent ergonomics, 84 against 70
  • Transparency & trust, 79 against 65

Watch for

The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental --agent-socket server or a container

Paperclip C

Best for Someone running several coding or operations agents who wants one place for tasks, budgets, approvals and history across harnesses.

Ahead on

  • Schema & documentation, 81 against 76
  • Security & auth, 64 against 58

Watch for

claude_local defaults dangerouslySkipPermissions to true and codex_local defaults to bypassing approvals and the sandbox, with agents running on the host

Verdicts

Mistral Vibe CLI

Apache-2.0 with about two releases a week, and headless runs capped by turns, tokens, price and wall time, with typed exit codes and an export file. File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and six shell-permission bypasses were fixed only on 12 September 2026.

Paperclip

Board approvals, budgets with a hard stop and an activity log sit above whichever harnesses do the work, and eleven stable versions shipped in 90 days. The Claude Code and Codex adapters skip permission prompts and the sandbox by default, and twelve security advisories, five of them critical, have been published since April 2026.

Before you call either

Mistral Vibe CLI

  1. Pass --agent on every -p run (plan is read-only). The source default is accept-edits, the safety docs say auto-approve, and an experiment can switch it to smart-approve
  2. Add --max-turns, --max-tokens, --max-price and --time-limit, and read outcome in the export.json that --output-dir writes. Exit 3 means a limit or a refusal
  3. Run in a container or behind --agent-socket before using --auto-approve. Vibe has no sandbox of its own on the host
  4. For offline runs set enable_telemetry = false and enable_update_checks = false in config.toml. The docs' enable_auto_update isn't the key the code reads
  5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with vibe --version

Paperclip

  1. Set PAPERCLIP_TELEMETRY_DISABLED=1 or DO_NOT_TRACK=1 before the first start. Telemetry is on by default
  2. Set dangerouslySkipPermissions and dangerouslyBypassApprovalsAndSandbox to false on agents that read untrusted input, or run them in a sandbox provider
  3. Install with Node.js 24.11 or newer, and install and sign in to each harness CLI on the host first. Paperclip assumes they are there
  4. Use --bind lan or --bind tailnet at onboarding for anything beyond one machine. The default local_trusted mode treats every request as the board admin
  5. Treat 409 on task checkout as owned by another agent and pick different work. The API docs say not to retry
