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.

Natura tinyNature

tinyNature is Natura's hosted personal agent, reached by message today or by voice through $149 HumanPods earbuds, with a published retention table and subprocessor list. No outside agent can call it, and no status page, changelog or dated release was found.

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

Natura tinyNature

  1. Don't plan to call tinyNature from another agent. @tinyNatureBot on Telegram is a chat for the owner, not an API.
  2. Send security reports to ops@natura.inc. The security.txt the site links returns 404.
  3. Check that tinyNature works on the owner's platform before they order HumanPods, as the HumanPods FAQ advises.

Disclosure

Natura tinyNature competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
