## Which one, for what

### CowAgent (C)

Good for: One technical owner who wants an assistant on WeChat, Feishu, DingTalk, Telegram, Slack or Discord with memory in local files and a choice of Chinese and Western model providers.

Ahead on:
- Reliability, 84 against 15
- Schema & documentation, 67 against 10
- Agent ergonomics, 59 against 10
- Payments & pricing, 60 against 30
- Maintenance & community, 83 against 0

Also in its favour:
- Free to start without a card
- Open source

Watch for: Source and Docker installs default to full-access, and no mode asks the owner before a shell command, a file send or an MCP call

### Hark Pro (F)

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

Also in its favour:
- No incidents deducted, where CowAgent loses 5 points for them

Watch for: External API and MCP access were not verified

## Verdicts

**CowAgent.** MIT software with seven releases in 90 days, memory kept as plain files in the owner's workspace and three per-session permission modes. Source and Docker installs default to full-access, no action asks for approval, and an open report of 31 July 2026 says group members could reach the owner's files through the bot.

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

## Before you call either

### CowAgent

1. Set `agent_permission_mode` to `workspace-write` or `read-only` before connecting any channel. Source and Docker installs default to `full-access`
2. Keep the bot out of group chats that include other people. Any member who mentions it reaches the same tools as the owner
3. Set `web_password` before changing `web_host` to `0.0.0.0`. The password is empty by default
4. Set `external_api_token` to enable `POST /v1/chat/completions`, and send `conversation_id` to keep one session. The `model` field does not select a model
5. Run it in a container for a hard boundary. The docs and the source both say the permission modes are not isolation

### 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.
