  • 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.

    Author:Dima Grossman
    Dima Grossman

    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.

  • Novu Connect

    Connect your AI agent to every channel your users already use, Slack, Microsoft Teams, WhatsApp, Telegram, and email, through one API. One agent, one synced conversation, live in minutes.

    Introducing Novu Connect: the Novu mark with channel icons orbiting it

    Your AI agent can think. Now it can talk.

    Novu Connect is live: the communication layer for AI agents. One agent, every channel your users already use, held together in one synced conversation, through a single API. You bring the agent. Connect handles identity, threading, and delivery.

    Meet ACI: Agent Communication Infrastructure

    Every wave of AI infrastructure solved one connection. MCP connected agents to tools. A2A connected agents to other agents. ACI connects agents to people.

    Agent Communication Infrastructure is the layer that lets an agent hold a real, two-way conversation with humans on the channels they already use. Novu Connect is the first ACI layer. Learn about the category.

    The ACI architecture: communication providers (Slack, WhatsApp, MS Teams, Telegram, email) connect through Novu for identity resolution, credential management, observability, and a unified conversation, to the agent brain (Agent SDK, LangChain, or Claude Managed Agent)
    The ACI stack: communication channels, the Novu bridge, and your agent's brain.

    One agent, every channel

    Reach your users on the surfaces they never close:

    • Slack: channels and DMs, answering in-thread with full context.
    • Microsoft Teams: the same agent inside the enterprise, with identity handled.
    • WhatsApp: a real back-and-forth, not a no-reply blast.
    • Telegram: fast, bot-friendly, community-native.
    • Email: the universal fallback, same thread, same context.

    Add a channel later, and your agent code does not change.

    Choosing where your agent listens and communicates in the Novu dashboard: Slack, Microsoft Teams, WhatsApp Business, and Novu Email, with Telegram, Google Chat and more coming soon
    Choosing where your agent listens and responds, in the Novu dashboard.

    One conversation, not five bots

    The hard part was never connecting a single channel. It was keeping one conversation coherent across all of them.

    Picture it: a user starts in Slack this morning, follows up from WhatsApp at lunch, and closes the loop by email tonight. To your agent, it is one thread. Same memory, same context. They never repeat themselves.

    Managing an agent's conversations in Novu: one synced thread per user across channels
    One synced conversation per user, across every channel.

    That is the part that single-channel connectors cannot do. Identity resolution and threading are handled for you, so the conversation follows your user across channels.

    Live in minutes: three ways to start

    Pick the path that fits how you work.

    1. CLI. Run one command:

    npx novu connect

    2. Agent-first. Paste a prompt where your agent already lives: "Add an agent to my app https://novu.co/agents.md". Sixty seconds later, your agent is live on a real channel, no account or API key required.

    3. Dashboard. Set it up visually in the Novu dashboard.

    A Novu agent live in Slack: the connected support agent replies in a thread and offers to continue setup in the dashboard

    Bring your own brain

    The agent logic stays yours. Bring Claude or your own code, and Connect carries it across every channel. We never run your agent's brain. Claude Managed agents are supported out of the box, on a free tier.

    Same infrastructure, now two-way

    Connect runs on the same delivery infrastructure behind your Novu notifications. No new stack, no migration. The one shift: it carries two-way agent conversations, not just the outbound messages you already send.

    Connect your first agent at novu.co/connect. This is day one, with more agent runtimes and channels on the way.

  • Account Security Upgrades: Passkeys, Smarter Client Trust, zxcvbn, Turnstile

    Sign in with a passkey, skip Client Trust when 2FA is on, get real password-strength scoring at signup, and run into bot challenges only when traffic looks suspicious.

    Author:Dima Grossman
    Dima Grossman

    Four account-security improvements ship together today: passkey login, Client Trust deferring to 2FA, zxcvbn-ts password scoring, and a smart CAPTCHA on sign-up.

    Existing sessions are unaffected.

    Passkey Login

    Passkeys are now a supported authentication method for Novu accounts.

    Sign up with email and password or SSO as usual, then add a passkey from Account settings → Security.

    Your platform authenticator (Touch ID, Windows Hello, a hardware security key or a password manager like 1Password or iCloud Keychain) handles the rest.

    On your next sign-in, pick Sign in with passkey.

    Passkeys are built on WebAuthn. The private key never leaves your device, so there's nothing phishable for an attacker to capture on our side.

    You can register up to 10 passkeys per account, and they stack alongside your password and 2FA. Passkeys are an additional method, not a replacement.

    Client Trust Now Defers to 2FA

    Client Trust is our defense against credential stuffing: when someone signs in with a valid password from a new device, we send a one-time code to their email or phone.

    The catch was that this fired even on accounts with 2FA already enabled. Signing in from a new laptop meant two prompts: enter your TOTP code, then approve the new device.

    That's now collapsed into the regular MFA flow.

    If you have 2FA configured (TOTP, SMS or backup codes), Client Trust skips automatically. Your second factor already covers the new device.

    If you don't have 2FA enabled, behavior is unchanged: new devices still require a verification code by email or phone.

    This only applies to password sign-ins. Passkeys, OAuth and email links bypass Client Trust entirely.

    If you've been meaning to turn on 2FA, this is the nudge.

    Stronger Password Feedback via zxcvbn

    Password strength at signup, change and reset is now scored with zxcvbn-ts, the OWASP-recommended library for measuring real password entropy rather than pattern-matching "8 characters, one number, one symbol."

    You'll see live strength feedback as you type, and a prompt when a password technically meets the basic rules but is still weak (Password1!, qwerty123, dictionary words with predictable substitutions).

    This sits on top of our existing NIST-based minimum requirements.

    Smarter Bot Protection on Sign-up

    Sign-up is where bots show up first.

    We've moved off the old invisible CAPTCHA and onto a smart variant that uses CDN-level signals to decide whether a sign-up attempt looks suspicious.

    If it does, the user gets a quick interactive challenge (typically a checkbox). If it doesn't, which is most of the time, the challenge stays out of the way.

    Less friction for real users, more for the scripted ones.

    Novu Copilot - describe a notification journey, get back a working workflow

    Describe a notification Workflow in plain English and Novu Copilot builds it for you, ready to review and ship from the dashboard.

    Novu Copilot generating a Workflow from a plain-English prompt

    Tell Copilot the journey you want - a re-engagement sequence, a trial conversion flow, a milestone celebration - and it assembles the Workflow and required steps inside Novu.

    Channels, timing and conditions are picked to match what you described, shaped by patterns Novu has seen work across thousands of production setups.

    Generated Workflows land in your Development Environment as real Novu Workflows. Keep them, discard them or re-run with a tweaked prompt. Promote to production the same way you promote any other Workflow - nothing ships until you say so.

    Copilot is in BETA and we ship improvements weekly based on what teams ask for. Generate your first Copilot Workflow in your dashboard.

    Novu MCP Server - your AI client, wired to your notification infrastructure

    Describe a notification flow in plain English and let your AI build, trigger, and debug it against your live Novu environment.

    No SDK. No dashboard clicking. No guessing at workflow IDs.

    AI prompt describing a multi-channel notification flow being turned into a Novu Workflow that ships across In-App, Email, Push, SMS and Slack

    The Novu MCP Server is now generally available.

    We first shipped it as a preview last July, then kept adding to it quietly. It now exposes 20+ tools - roughly ten more than launch day - covering subscriber CRUD, bulk triggering, event cancellation, and integration management.

    If you've been meaning to connect your AI to Novu, this is the version to try. The model stops generating code from training data and starts reading your actual environment.

    Build workflows in plain English

    Instead of scaffolding a workflow in the dashboard and wiring each channel step by hand, describe the outcome. The AI reads your environment, picks real providers, and stitches the steps together. Ask it to iterate and it edits the same workflow in place.

    "Create a workflow called order-shipped that sends an in-app notification when an order ships, then follows up with an email after 24 hours if the user hasn't seen it."
    Novu Workflow built from an AI prompt, fanning out across Email, Push, SMS, Slack and In-App on the free tier's 10k events per month

    Debug, inspect, and bulk-operate from chat

    Once a workflow is live, keep the assistant in the loop. Because it reads live delivery data and subscriber state, routine investigation, maintenance, and triage stop requiring a second tab:

    "Why didn't the order-confirmation notification reach subscriber user_123?"
    "Find subscriber user_789 and mute their Slack notifications, but keep email and push active."
    "Bulk trigger the re-engagement workflow for these 500 subscribers."
    "List my active integrations and tell me which are primary for each channel."

    The last two hit tools we shipped in this release. Bulk triggering, event cancellation, integration inspection, and primary-provider management all came online after the original preview.

    Connect your tool in two minutes

    Copy a Secret Key from dashboard.novu.co/settings/api-keys and point your AI tool at the Novu server. Claude Code is one command:

    claude mcp add --transport http novu https://mcp.novu.co/ \
      --header "Authorization: Bearer your-novu-api-key"

    Cursor uses Settings > Tools & Integrations. Codex reads ~/.codex/config.toml. Claude Desktop connects through npx mcp-remote (Node.js 18+). EU environments use https://mcp.novu.co/?region=eu. Any other MCP-compatible client works with the same URL and Bearer auth pattern.

    Missing a tool? Request it

    The server is a living product. If there's an action you want to drive from your AI client that isn't covered yet, request it on the Novu roadmap and we'll prioritize based on demand.

  • Code Steps

    Every channel step in a Novu Workflow can now be managed as TypeScript in your codebase - email, SMS, push, chat, and in-app.

    Novu Code Steps cover image showing the npx novu step publish CLI command at the center, connected to five notification channels: Email (step.email()), In-App (step.inApp()), SMS    (step.sms()), Chat (step.chat()), and Push (step.push())

    Each step now has two modes: Editor (visual) and Custom Code (developer-managed via code). Switch any step to Custom Code mode, and the dashboard shows a pre-filled CLI command.

    Switch any step to Custom Code mode and the dashboard shows the publish command, pre-filled and ready to run.

    Run it to scaffold a placeholder handler and deploy it:

    npx novu step publish \
      --workflow your-workflow-id \
      --step your-step-id \
      --secret-key nv-sk-...

    React Email for Email Steps

    For email steps, pass --template to wire a React Email component directly:

    npx novu step publish \
      --workflow onboarding \
      --step welcome-email \
      --template ./emails/welcome.tsx \
      --secret-key nv-sk-...

    Your React Email components stay in your repo, go through PR review, and are versioned alongside your application code.

    Controls: Dashboard Editing Without Code Changes

    Define a controlSchema in your code steps to expose editable fields in the Novu dashboard. Developers set the structure and defaults - non-technical teammates override copy without touching code.

    Once published, controls defined in your handler appear as editable fields in the dashboard - no code change needed to update copy.

    Mix Custom Code steps and Editor steps freely within the same Workflow.

    Switch any step to Custom Code mode and copy the pre-filled command from the step editor to get started.
