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**Novu.** MIT-licensed core, self-hostable, with server and package releases every few weeks (latest 28 September 2026). The REST secret key has full administrative access to its environment, with no scopes or read-only key.\n\n## Before you call either\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### Novu\n\n1. Send `Authorization: ApiKey \u003ckey\u003e` to the REST API. Bearer is for the MCP server\n2. Ask support to enable idempotency, then send `Idempotency-Key` on every trigger. A 409 means the first call is still running\n3. Use eu.api.novu.co and eu.mcp.novu.co for an EU account. A US key won't authenticate there\n4. Pass `environmentId` from `get_environments` on MCP calls. OAuth sessions default to Development\n5. Keep `limit` at 100 or below on list calls. Higher values return 422\n\n## Questions\n\n### Which is better for AI agents, MagicBell or Novu?\n\nNovu scores 64.2 (B) on agent readiness against MagicBell's 58.8 (C), and leads in every scored category.\n\n### Do MagicBell and Novu need an API key?\n\nMagicBell needs an API key. Novu takes an API key or an OAuth sign-in.\n\n### Can an agent call MagicBell and Novu without installing anything?\n\nYes. MagicBell has a hosted endpoint at https://api.magicbell.com/v2 and Novu at https://api.novu.co/v1.\n\n### Are MagicBell and Novu open source?\n\nNo open-source release is listed for MagicBell. Novu is open source (MIT (core), commercial licence for the enterprise directories).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/magicbell-vs-novu.json, and with the fewest tokens: https://www.anchorterminal.com/compare/magicbell-vs-novu.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"magicbell\", \"b\": \"novu\"}`.
