  • Novu Chat SDK Adapter

    Bring your Chat SDK agent to Slack, Teams, WhatsApp, Telegram, and email: deliver multi-channel notifications from one trigger, resolve every channel to one unified subscriber, and drop in React connect components to put channels in front of your end-customers.

    The @novu/chat-sdk-adapter is now available. Wire it into your Chat SDK app and Novu manages credentials, identity, and delivery across Slack, Microsoft Teams, WhatsApp, Telegram, and email.

    npm install @novu/chat-sdk-adapter

    Multi-channel notifications from one trigger

    Define a workflow once in Novu with the channels you want, then fire a single trigger from any handler. Novu fans out to every step — Slack, email, WhatsApp, and more — and routes replies back through the same agent loop, so proactive notifications and conversational replies share one handler set.

    const ctx = getNovuContext(thread);

// One trigger delivers to every channel in the workflow.
await ctx.trigger("order-shipped", {
  payload: { orderId: "1234", trackingUrl: "https://example.com/track/1234" },
});

    One unified subscriber across every channel

    Every channel resolves to a single Novu subscriber mapped to your own user, so your agent always knows who it's talking to — with email, phone, locale, custom data, and the canonical conversation history available inside any handler.

    const ctx = getNovuContext(thread);

const subscriber = await ctx.getSubscriber(); // email, phone, locale, custom data
const history = await ctx.getHistory();       // canonical transcript — ideal for LLM context

    Expose channels to end-customers with connect components

    Drop the prebuilt SlackConnectButton from @novu/react into your app so your end-customers can install and connect their own Slack workspace to your agent — OAuth, credentials, and Slack Connect handled by Novu. Microsoft Teams and Telegram connect buttons are in pre-release.

    import { SlackConnectButton } from '@novu/react';

<SlackConnectButton
  integrationIdentifier={integrationIdentifier}
  connectionIdentifier={`${subscriberId}:${integrationIdentifier}:${agent.identifier}`}
  connectionMode="subscriber"
  connectLabel={`Install ${agent.name} ↗`}
  connectedLabel="Connected to Slack"
  onConnectSuccess={handleSlackOAuthSuccess}
/>

    Get started with npx novu connect --runtime chat-sdk, or read the connect components docs.

  • In-conversation MCP authorization and message queues

    Connect external MCPs during the conversation and process incoming messages one at a time for a more predictable chat experience.

    Connecting external MCPs is now part of the conversation itself, instead of a separate setup step. When an agent needs access to a tool, it can prompt the user to connect it right at that moment and then continue the original request once access is granted. This makes the experience feel much more natural and reduces the friction of getting started with tool-powered workflows.

    We also introduced session-level tool access, so connected tools are available only where they are relevant. That gives users a clearer sense of control over what an agent can use during a conversation, while helping keep tool usage focused on the task at hand.

    Conversation queue

    We also improved how conversations behave when several messages arrive quickly. Messages are now processed in order, one at a time, instead of competing in parallel. This creates a more predictable experience in fast-moving chats and helps reduce confusing or out-of-sequence responses.

    Each queued message gets its own ⏳ indicator, and the indicator is removed when the message is processed.
