Novu Connect is built on the Agent Communication Infrastructure (ACI), the infrastructure layer that handles how agents communicate, so your agents can hold real conversations across messaging platforms with users, on the channels they already use. ACI draws a hard boundary between two concerns:
  • Communication infrastructure: Webhook ingestion, message normalization, conversation state, identity resolution, and delivery across channels. ACI owns this layer.
  • Agent intelligence: Your LLM, prompts, tools, managed agent configuration, business logic, or custom runtime. You own this layer.
The result is that you can create an agent once and make it available across connected channels. ACI routes messages in, sends replies out, preserves conversation context, and removes the need to rebuild communication plumbing for every platform.

What is ACI?

Learn how ACI works, what it solves, and where it draws the line between infrastructure and intelligence.

​
Connect the agent

Novu Connect accepts two kinds of agent brains. You choose how you want to bring it.

​
External connectors

Delegate the agent logic entirely to a managed platform such as Claude Managed Agents. You configure the agent’s behavior, system prompt, tools, skills, and MCP servers and the platform runs the intelligence.

Managed agent

Set up a fully managed agent powered by Claude. No custom server code required.

​
Custom code

Write your own agent logic. Handle events, call any LLM or API, and reply using the Novu agent SDK. Compatible with AI SDK, LangChain, Mastra, OpenAI SDK, and any custom code of your choosing.

AI SDK

Build with the Vercel AI SDK and @novu/framework/ai-sdk.

LangChain

Build with LangChain and @novu/framework/langchain.

Mastra

Build with Mastra and @novu/framework.

​
How a conversation flows

ACI turns channel-specific messages into a standard communication flow between the user and your agent brain.
  1. A user sends a message on Slack, Teams, WhatsApp, or another supported channel.
  2. Novu ingests the webhook, normalizes the event, and resolves the user’s identity.
  3. Novu sends the event to your agent brain with full conversation context.
  4. Your agent processes the message and responds.
  5. Novu delivers the reply back to the correct platform thread.
  6. Novu persists the conversation and makes it visible in the Connect dashboard.
