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.

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 Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
