## Which one, for what

### Kiro CLI (C)

Good for: Teams on AWS that want one agent configuration across terminal, IDE and web, with central permission policy, prompt logging to their own S3 bucket and IAM Identity Centre sign-in.

Watch for: Free and individual paid accounts have content used for service improvement, including model training, unless they opt out

### Paperclip (C)

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

Ahead on:
- Reliability, 66 against 57
- Payments & pricing, 60 against 40
- Maintenance & community, 78 against 73

Also in its favour:
- Open source

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

**Kiro CLI.** Permission rules follow deny over ask over allow, cloned repositories can't add rules, and a headless session treats every ask as a deny. Content from Free and individual paid accounts is used for service improvement, including model training, unless the user opts out, and API keys for pipelines need a paid plan.

**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

### Kiro CLI

1. Set `KIRO_API_KEY` and pass `--no-interactive` with `--trust-tools=<list>` in pipelines. Keep `--trust-all-tools` for disposable environments
2. Pass `--require-mcp-startup` when a run depends on MCP tools. Without it a failed server is logged and the run continues
3. Pass `--no-interactive` whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows
4. Run `kiro-cli settings telemetry.enabled false` and turn off content collection on Free and individual plans. Both are on by default
5. Export variables in the shell before starting. Since 2.24.0 a project `.env` file is no longer loaded into sessions, MCP servers or tools

### 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
