## Which one, for what

### Cursor CLI (F)

Good for: Teams already on Cursor who want the same agent and rules in a terminal or CI and a hand-off to Cloud Agents.

Watch for: No CLI changelog, and versions are dates

### 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.

Ahead on:
- Reliability, 57 against 27
- Schema & documentation, 79 against 39
- Agent ergonomics, 67 against 42
- Security & auth, 66 against 46
- Payments & pricing, 40 against 25
- Maintenance & community, 73 against 62
- Transparency & trust, 67 against 59

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

## 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.

**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.

## 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

### 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
