Novu + Memtro

Only when you ask, and only what it has been granted: trigger a workflow, sending its notifications to named subscribers or a topic; cancel a triggered workflow's pending digests and delays; create a subscriber; update a subscriber's name, email, phone, locale or timezone; delete a subscriber with their messages, preferences and topic subscriptions; create a topic; add subscribers to a topic; remove subscribers from a topic; delete a topic; switch a workflow on or off; mark a subscriber's inbox notification read, unread, archived or unarchived; delete a message. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.

A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.

Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded.

Secret key, plus region. In the Novu dashboard, pick the environment at the top, open API Keys and copy the Secret Key, not the Application Identifier.

Yes. Turn events on in the connection's Events tab on the Connections page, then add the address it shows as a webhook in Novu, choosing the same kinds; the tab shows Novu's own steps. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
