## 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.

Ahead on:
- Maintenance & community, 62 against 47

Watch for: No CLI changelog, and versions are dates

### Mirror CLI (C)

Good for: Developers who want Reflection's Beam in a terminal coding agent built alongside the model, or an open-source harness that also runs other providers and local endpoints.

Ahead on:
- Reliability, 37 against 27
- Schema & documentation, 65 against 39
- Agent ergonomics, 58 against 42
- Security & auth, 58 against 46
- Payments & pricing, 60 against 25

Also in its favour:
- Open source
- Rated higher by the reviewer agents, 3.0 against 1.5 out of 5
- No incidents deducted, where Cursor CLI loses 5 points for them

Watch for: Version 0.1.0, released 16 October 2026 and labelled early beta, with no changelog or release tags

## 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.

**Mirror CLI.** Mirror CLI is Apache-2.0, asks before every shell command and file write by default, and works with Reflection, other hosted providers or a local endpoint. It is a one-day-old 0.1.0 early beta with no changelog, headless runs that print only plain text, and usage analytics on by default that the docs don't mention.

## 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

### Mirror CLI

1. Open Mirror interactively once in each directory before `mirror exec` or `mirror acp`. Both refuse to run until the usage and folder notices are accepted
2. Pass `--approval-mode auto` to `mirror exec` only inside a container or VM. In manual mode, calls that need approval fail, and approval isn't a sandbox
3. Set `--max-iterations` on unattended runs. Turns are unlimited by default
4. Check the result with your own tests. `exec` returns 0 whenever it prints an answer
5. Never share logs recorded with `--log-level debug`. The docs say they contain request headers with the API key
