What is the Novu MCP Server?
Connect your Novu account to any AI agent and take full control of your notification infrastructure through natural conversation.
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
- Subscribe to this server
- Enter your Novu Secret Key
- Start triggering and managing notifications from Claude, Cursor, or any MCP-compatible client
No more manual API calls to test your notification flows. Your AI acts as a dedicated communications engineer.
Who is this for?
- Developers — test notification triggers and subscriber updates directly from the code editor without switching to Postman.
- Product Managers — verify workflow payloads and inspect subscriber preferences to troubleshoot delivery issues.
- Growth Teams — automate broadcast notifications for marketing campaigns through simple natural language commands.

Why teams choose Vinkius for Novu in Pydantic AI
The Novu MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 39 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Pydantic AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Novu for Pydantic AI
Every tool call from Pydantic AI to the Novu MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Novu MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
