Connect Your AI Tool
Nitrosend is designed to be controlled by AI. Instead of clicking through dashboards, you connect your AI tool and manage everything — campaigns, flows, contacts, templates, analytics — through natural language.
MCP: The Fastest Way to Connect
MCP (Model Context Protocol) is an open standard that lets AI assistants connect directly to external tools. Nitrosend has a native MCP server, which means Claude, ChatGPT, Cursor, Codex, Gemini CLI, VS Code, Windsurf, Zed, and other MCP-compatible clients can access your full email marketing platform with zero middleware.
What MCP gives your AI
When you connect via MCP, your AI assistant gets:
- 21 specialized tools — compose emails, build flows, manage contacts, check analytics, control delivery, and more
- Live resources — your brand identity, account state, platform guide, and email design schema
- Full context — your AI knows your brand colors, tone of voice, and sending history before it writes a single email
- Two-way control — create, preview, test, approve, send, pause, and analyze, all from conversation
MCP vs REST API
| MCP | REST API | |
|---|---|---|
| Best for | Claude, ChatGPT, Cursor, Codex, Gemini CLI, VS Code, Windsurf, Zed | Custom apps, Zapier, n8n, Make, server-side integrations |
| Setup | 1 click, 1 command, or a short JSON config + OAuth sign-in | API key + define function calls or curl |
| AI context | Full — brand, schema, guide, account state | You provide context manually |
| Tools | 21 purpose-built tools with validation | Raw HTTP endpoints |
| Coding required | No | Minimal to moderate |
Use MCP whenever possible. It gives your AI far more context about your account, brand, and email best practices than the REST API alone. The result is better emails with less prompting.
