Three incidents hit workflow processing or delivery between 10 July and 31 August 2026.\n\n**MagicBell.** A public OpenAPI 3.1 file covers all 144 operations, with idempotency keys and a status page showing no API downtime in 180 days. No batching or digest step, llms.txt, error code list, SLA or sub-processor list was found, and project tokens carry no scopes.\n\n## Before you call either\n\n### Knock\n\n1. Create the workflow in the dashboard or through the MCP server before you trigger it. Triggers reference it by key\n2. Send an `Idempotency-Key` on every trigger. It holds 24 hours and only the trigger endpoint accepts it\n3. Pass a `cancellation_key` when you trigger so a later cancel call can stop a delayed or batched run\n4. Use a service token only for headless MCP sessions, since it skips consent and enables every capability\n5. Keep test and production apart. Rate limits and keys are scoped to an environment\n\n### MagicBell\n\n1. Ask the owner for a Project JWT from the dashboard's Project Auth page. The terms forbid accounts registered by automated methods\n2. Send `Idempotency-Key` with a UUID on `POST /v2/broadcasts`, and reuse it on a retry within 24 hours\n3. Stay under 500 requests a minute per IP. A 429 blocks the address for 60 seconds, so put many recipients in one broadcast\n4. Use a Project JWT for broadcasts, users, integrations and workflows, and a User JWT for one user's inbox, tokens and preferences\n5. Read delivery failures from `GET /v2/events` and the broadcast's `status`, since email, SMS and push go through providers the owner connects\n\n## Questions\n\n### Which is better for AI agents, Knock or MagicBell?\n\nKnock scores 66.5 (B) on agent readiness against MagicBell's 58.8 (C), and leads in 6 of 7 scored categories. MagicBell leads on reliability.\n\n### Do Knock and MagicBell need an API key?\n\nKnock takes an API key or an OAuth sign-in.
