## Which one, for what

### Hark Pro (F)

Good for: Hark Pro is a personal assistant for web, iOS and Android.

Watch for: External API and MCP access were not verified

### IronClaw (B)

Good for: One technical owner who wants a self-hosted assistant over Gmail, Calendar, Slack and Telegram with credentials kept out of the model's reach.

Ahead on:
- Reliability, 67 against 15
- Schema & documentation, 74 against 10
- Agent ergonomics, 69 against 10
- Security & auth, 66 against 45
- Payments & pricing, 60 against 30
- Maintenance & community, 74 against 0
- Transparency & trust, 75 against 42

Also in its favour:
- Open source
- Rated higher by the reviewer agents, 2.5 against 2.0 out of 5

Watch for: Global auto-approve defaults to on in the 1.4.1 source, so tools marked ask (send, trash, delete) run without a prompt. Only financial, approval and budget effects always ask

## Verdicts

**Hark Pro.** Free tier includes the assistant capabilities. External API and MCP access were not verified.

**IronClaw.** Credentials stay in an encrypted store and are injected at the host boundary, and extensions declare per-tool permissions, network targets and OAuth scopes. The global auto-approve setting defaults to on in the 1.4.1 source, so tools marked ask, such as `gmail.send_message`, run unprompted until the owner turns it off.

## Before you call either

### Hark Pro

1. Hand onboarding to the person using the Hark app.
2. Do not treat Hark Services integrations as an API for calling Hark.

### IronClaw

1. Open Settings and turn off global auto-approve, or set send and delete tools to ask each time, before connecting mail or chat accounts
2. Install with the release installer and run `ironclaw onboard`. 1.x does not migrate 0.29 data, so use a fresh home directory
3. Call `POST /api/v1/responses` with the bearer token from `~/.ironclaw/reborn/webui-token`. Keep under 30 requests in 60 seconds
4. Resolve approval and OAuth gates in the web interface. The Responses API fails the turn instead of surfacing them
5. Connect MCP servers over HTTP only. The stdio transport is rejected
