No reviewer inbox, Slack app or email, so the human side is your code.\n\n**Permit MCP Gateway.** No SDK or client change, since the client points at the gateway URL and keeps its tool list. Approvals are Enterprise only, through a demo, with no published price.\n\n## Before you call either\n\n### Inngest\n\n1. Use `step.waitForSignal()` when one run waits for one answer, and `waitForEvent` only when one answer resumes many runs\n2. Register the wait before you send the approval request, or check the external state first, since early events are missed\n3. Use a unique approval ID per tool call and `match` on it, so parallel approvals resolve independently\n4. Treat `null` or `undefined` as a timeout and decide on purpose whether that rejects, approves or escalates\n5. Set an event `id` when sending the answer, so a retried send is dropped within 24 hours\n\n### Permit MCP Gateway\n\n1. Expect a waiting message before an approval-gated tool returns, and don't retry the call while it waits\n2. Read the rejection reason in the error and change approach instead of calling the same tool again\n3. Treat a timeout as a rejection and ask the user to have an admin online before a batch of destructive calls\n4. Stay connected while waiting, since dropping the connection cancels the request\n5. On a 429 with `rate_limited`, back off for a few seconds and grow the wait on each retry\n\n## Other comparisons with Inngest or Permit MCP Gateway\n\n- [gotoHuman vs Inngest](https://www.anchorterminal.com/compare/gotohuman-vs-inngest.md)\n- [gotoHuman vs Permit MCP Gateway](https://www.anchorterminal.com/compare/gotohuman-vs-permit-mcp-gateway.md)\n- [Inngest vs Orkes Conductor Human tasks](https://www.anchorterminal.com/compare/inngest-vs-orkes-conductor.md)\n- [Inngest vs Pushary](https://www.anchorterminal.com/compare/inngest-vs-pushary.md)\n- [Inngest vs Temporal](https://www.anchorterminal.com/compare/inngest-vs-temporal.md)\n- [Inngest vs Trigger.dev](https://www.anchorterminal.com/compare/inngest-vs-trigger-dev.md)\n- [Orkes Conductor Human tasks vs Permit MCP Gateway](https://www.anchorterminal.com/compare/orkes-conductor-vs-permit-mcp-gateway.md)\n- [Permit MCP Gateway vs Pushary](https://www.anchorterminal.com/compare/permit-mcp-gateway-vs-pushary.md)\n- [Permit MCP Gateway vs Temporal](https://www.anchorterminal.com/compare/permit-mcp-gateway-vs-temporal.md)\n- [Permit MCP Gateway vs Trigger.dev](https://www.anchorterminal.com/compare/permit-mcp-gateway-vs-trigger-dev.md)\n",
