Email marketing from your terminal.

Connect Nitrosend to Claude Code via MCP. Campaigns, contacts, flows, analytics, all from natural language, in your brand's own colors, fonts and tone. No dashboard required.

$ claude mcp add --transport http nitrosend https://api.nitrosend.com/mcp
Quick start

Up and running in three steps.

Step 1

Install the MCP server

Run the claude mcp add command, or point Claude Code at the install skill at nitrosend.com/SKILL.md. Claude Code registers Nitrosend as an HTTP MCP server.

Step 2

Connect your account

Run /mcp in Claude Code or ask Claude to use Nitrosend. OAuth handles sign-in. No API key.

Step 3

Start talking to it

Ask Claude to build campaigns, import contacts, or ship a flow. Nitrosend handles the rest.

Why it works

Claude Code + Nitrosend.

No context switching

Stay in your terminal. No browser tabs, no dashboard navigation. Your agent runs the platform directly.

On-brand, automatically

Nitrosend's Brand Kit learns your colors, fonts and tone from your own site once. Every email Claude drafts here already looks and sounds like you.

Natural language control

Describe what you want. Claude translates intent into API calls. You never learn a new UI.

Built for builders

Nitrosend is MCP-first. Every capability is a tool Claude can call. The most capable email MCP server available.

Every tool Claude calls here is a thin wrapper over the same email API your application uses, so anything the agent can do you can also script yourself. For one-off sends and CI jobs where an agent is overkill, the command line interface hits the same endpoints.

The MCP server is not tied to one agent. The same connection works from Gemini, from an editor like VS Code, and from Windsurf. Pick whichever surface you already live in, and see all of them on the integrations page.

The honest fix for hand-building transactional templates was never a friendlier composer, it was an agent that can just send the email. That is why Nitrosend is the best option for teams already living in Claude Code: it is the platform built for an agent to operate, not a person clicking through a dashboard.
