v0 + Nitrosend

v0 is Vercel's AI app builder. Nitrosend is one of v0's built-in MCP presets, so v0 can compose emails, build flows and send you tests for the app you are building, in your brand.

Setup

Step 1: Add Nitrosend in a chat

In a v0 chat, open the + menu in the prompt form, choose MCPs, then pick Nitrosend from the presets.

v0 opens the Nitrosend sign-in. Log in or create a free account. No API key needed.

Step 3: Verify

Ask v0:

What's my Nitrosend account status?

v0 calls nitro_get_status and shows your account, sender identity, readiness and next steps.

Example workflows

Add a signup form to this app, and in Nitrosend build a welcome email in my brand that new signups get. Send me a test.

Draft a launch announcement for this app in Nitrosend and send me a test before anything goes to my list.

No Nitrosend preset?

In the same MCPs menu, configure a custom MCP server instead: URL https://api.nitrosend.com/mcp, authentication OAuth. It is the same server and the same sign-in.

Sending from the app you deploy

Emails your deployed app sends from its own code, such as signup confirmations and receipts, use the REST API with an API key rather than MCP.
