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
