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.

Talorys

Talorys is an MIT-licensed assistant its owner deploys to their own Cloudflare account, with no telemetry, a documented threat model and code-enforced confirmation for destructive tools. It is two days old at version 0.1.5, has no mail, calendar or payment connections, and no interface for an outside agent.

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

Talorys

  1. Run npx create-talorys@latest with Node.js 22 or later and a Cloudflare login or an API token with Workers, Pages and Workers AI permissions.
  2. Don't script the /api routes. They need the owner's session cookie and CSRF header and aren't documented for other callers.
  3. Update with npx create-talorys@latest update. Only the latest version gets security fixes.

Other comparisons with CowAgent or Talorys

Disclosure

Talorys 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.
