Its default launch binds all interfaces with sign-in off and permissive CORS, there is no security policy, and two CVEs in 2026 covered a shell-tool RCE and a multi-user MCP bypass, both fixed.\n\n**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.\n\n## Before you call either\n\n### DeepTutor\n\n1. Run `deeptutor run \u003ccapability\u003e \"...\" --format json` and read the `done` event's `session_id`; pass `--session` to continue the same session\n2. Configure with `deeptutor config apply setup.json --check` first, naming keys through `api_key_env`; literal keys are rejected\n3. Before exposing it beyond one machine, enable sign-in in `auth.json`, set exact `cors_origins` and set `BACKEND_HOST=127.0.0.1` where loopback is wanted\n4. Run 1.4.10 or later. Earlier versions carry CVE-2026-51870 (shell tool RCE, fixed in 1.4.1) and CVE-2026-58168 (multi-user MCP bypass)\n5. Set `sandbox_allow_subprocess` to false where generated code must run only in the runner sidecar or bubblewrap\n\n### Natura tinyNature\n\n1. Don't plan to call tinyNature from another agent. @tinyNatureBot on Telegram is a chat for the owner, not an API.\n2. Send security reports to ops@natura.inc. The security.txt the site links returns 404.\n3. Check that tinyNature works on the owner's platform before they order HumanPods, as the HumanPods FAQ advises.\n\n## Questions\n\n### Which is better for AI agents, DeepTutor or Natura tinyNature?\n\nDeepTutor scores 62.7 (B) on agent readiness against Natura tinyNature's 14.9 (F), and leads in every scored category.\n\n### Are DeepTutor and Natura tinyNature open source?\n\nDeepTutor is open source (Apache-2.0). No open-source release is listed for Natura tinyNature.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deeptutor-vs-natura.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deeptutor-vs-natura.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deeptutor\", \"b\": \"natura\"}`.
