Verdicts

DeepTutor

DeepTutor runs on the owner's machine under Apache 2.0, ships releases every few days with upgrade notes, and gives other agents a JSON CLI with resumable sessions. 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.

Hark Pro

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

Before you call either

DeepTutor

  1. Run deeptutor run <capability> "..." --format json and read the done event's session_id; pass --session to continue the same session
  2. Configure with deeptutor config apply setup.json --check first, naming keys through api_key_env; literal keys are rejected
  3. 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
  4. 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)
  5. Set sandbox_allow_subprocess to false where generated code must run only in the runner sidecar or bubblewrap

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.
