The `DurableTask` worker status path looked up durable event log entries by a caller-supplied task UUID with no tenant filter, so a holder of any tenant's token who knew another tenant's task UUID could read its entries. The advisory names Hatchet Cloud as affected and calls exploitation very unlikely because the IDs are random UUIDs. Fixed in 0.106.1. It is the event log this listing is graded on, so 2 points for a fixed path. https://github.com/hatchet-dev/hatchet/security/advisories/GHSA-992g-9cr3-vm5x (read through https://api.osv.dev/v1/vulns/GHSA-992g-9cr3-vm5x)",

Hatchet supplies only the pause and resume. It has no approver inbox, notification channel or record of who answered, and its MCP server cannot push the event.\n\n**Temporal.** Waits of any length with a timeout survive worker restarts and deploys. No reviewer inbox, notifications or routing, so the human side is all your code.\n\n## Before you call either\n\n### Hatchet\n\n1. Put the approval wait in a durable task, and keep API calls, database reads and random values in child tasks, because the code between checkpoints is replayed\n2. Add a sleep condition in the same or group as the event condition to set a deadline, and treat the sleep firing first as a timeout\n3. Give the event a scope and the wait a lookback window when the answer can arrive before the wait starts. Both must be set together\n4. Filter with a CEL expression such as `input.user_id == '1234'` so one approval key cannot resume another request's task\n5. Push the answer with the SDK's event push or `POST /api/v1/tenants/{tenant}/events`. The MCP server has no tool for it\n6. Grant the MCP server one profile with `hatchet mcp auth --grant \u003cprofile\u003e`. It refuses profiles that were not granted\n\n### Temporal\n\n1. Put the decision in a typed Signal payload (approver, decision, comments, timestamp) instead of a bare boolean\n2. Always wait with a timeout and treat the timeout path as a rejection or an escalation on purpose\n3. Use the workflow ID as the approval ID, so the reviewer's tool only needs one value to send the Signal\n4. Use an Update instead of a Signal when the approver's tool needs an acknowledgement back\n5. Expect `ResourceExhausted` under load and let the SDK retry it, since signals are throttled last\n\n## Questions\n\n### Which is better for AI agents, Hatchet or Temporal?\n\nTemporal scores 77.2 (BB) on agent readiness against Hatchet's 68.3 (B), and leads in 4 of 7 scored categories. Hatchet leads on payments \u0026 pricing.\n\n### Are Hatchet and Temporal open source?\n\nYes. Hatchet is open source (MIT). Temporal is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/hatchet-vs-temporal.json, and with the fewest tokens: https://www.anchorterminal.com/compare/hatchet-vs-temporal.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"hatchet\", \"b\": \"temporal\"}`.
