What you can do

Triggering & Events — Trigger single, bulk, or broadcast notifications across Email, SMS, Push, and Chat using workflow identifiers.
Subscriber Management — Create, retrieve, update, and search for subscribers to maintain an up-to-date communication database.
Preference Controls — Inspect and update subscriber-specific notification preferences to ensure compliance and user satisfaction.
Workflow Cancellation — Cancel active or pending workflows, such as digests or delayed notifications, using transaction IDs.
Tenant Context — Manage notifications within specific tenant contexts for multi-tenant applications.

How it works

FAQ

Frequently asked questions

Can I send a notification to all my subscribers at once?

Yes! Use the trigger_broadcast tool with your workflow name. This will initiate a notification event for every existing subscriber in your Novu environment.

How do I find a subscriber if I only have their email address?

You can use the search_subscribers tool and provide the email as a parameter. The agent will return the subscriber's full profile, including their unique subscriberId.

Is it possible to stop a notification that is currently in a 'delay' or 'digest' state?

Yes. By using the cancel_trigger tool with the corresponding transactionId, you can halt any active or pending workflow execution before it reaches the final delivery.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.

Can I trace MCP tool calls in LangSmith?

Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
