## Verdicts

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

**OpenClaw.** Self-hosted under the MIT licence, with state, memory and credentials kept on the owner's machine and no paid tier. A fresh install runs tools on the host with full access, no approval prompt and no sandbox, and the project has published 722 security advisories since January 2026, 14 of them critical.

## 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.

### OpenClaw

1. Set a session permission mode of `guarded` or `workspace`, or `tools.exec.mode`, before connecting mail. The default runs host commands without approval
2. Turn on `agents.defaults.sandbox` for any agent that reads mail, web pages or attachments. Sandboxing is off by default
3. Set `tools.message.crossContext.allowAcrossProviders` and `allowWithinProvider` to `false` to confine sends to the current conversation
4. Route incoming mail to a restricted reader agent, as the IMAP and Gmail guides show, and deny `gateway`, `cron`, `sessions_spawn` and `sessions_send` for it
5. Run `openclaw security audit` after setup, and treat the Gateway token as an owner credential. `POST /tools/invoke` accepts it with full operator access
