Google Gemini + Nitrosend MCP
Gemini CLI has native MCP support, giving you the full Nitrosend toolkit — 20 tools, live brand context, and account state — directly in your terminal.
Setup
Step 1: Add the MCP server
Add to your Gemini CLI settings (~/.gemini/settings.json):
{
"mcpServers": {
"nitrosend": {
"httpUrl": "https://api.nitrosend.com/mcp"
}
}
}
Step 2: Sign in
On first use, Gemini opens your browser for Nitrosend sign-in. Log in or create a free account — no API key needed.
Step 3: Use it
gemini "Check my Nitrosend account status and draft a welcome email"
gemini "Create a campaign for our product launch and target my VIP segment"
MCP gives Gemini your full brand context — colors, fonts, tone of voice — so emails it creates are on-brand without extra prompting.
Example workflows
Set up brand + compose
gemini "Scrape my brand from https://mysite.com and draft a product announcement email"
Build a flow
gemini "Create a welcome flow that sends 3 emails over a week when someone subscribes"
gemini "Show me insights for my last campaign compared to benchmarks"
Function Calling via Google AI SDK (Alternative)
For programmatic integration or Google AI Studio, you can define Nitrosend operations as function declarations and call the REST API directly. This requires an API key from Settings > API Keys in the Nitrosend dashboard.
Define function declarations
from google import genai
from google.genai import types
client = genai.Client()
nitrosend_tools = types.Tool(
function_declarations=[
types.FunctionDeclaration(
name="send_email",
description="Send a transactional email to one recipient immediately",
parameters=types.Schema(
type=types.Type.OBJECT,
properties={
"to": types.Schema(type=types.Type.STRING, description="Recipient email"),
"subject": types.Schema(type=types.Type.STRING, description="Subject line"),
"body": types.Schema(type=types.Type.STRING, description="Email body (HTML)")
},
required=["to", "subject", "body"]
)
),
types.FunctionDeclaration(
name="list_campaigns",
description="List all email campaigns with their status",
parameters=types.Schema(
type=types.Type.OBJECT,
properties={
"status": types.Schema(
type=types.Type.STRING,
description="Filter by status: draft, active, paused, completed"
)
}
)
)
]
)
Handle function calls
import requests
NITROSEND_API_KEY = "nskey_live_your_key_here" # From Settings > API Keys
BASE_URL = "https://api.nitrosend.com/v1/my"
HEADERS = {
"Authorization": f"Bearer {NITROSEND_API_KEY}",
"Content-Type": "application/json"
}
def execute_nitrosend_function(name, args):
if name == "send_email":
resp = requests.post(f"{BASE_URL}/messages", headers=HEADERS, json={
"channel": "email", "to": args["to"],
"subject": args["subject"], "body": args["body"]
})
return resp.json()
elif name == "list_campaigns":
params = {"status": args["status"]} if "status" in args else {}
resp = requests.get(f"{BASE_URL}/campaigns", headers=HEADERS, params=params)
return resp.json()
Key API endpoints
| Function name | API call | What it does |
|---|
send_email | POST /v1/my/messages | Send a single email immediately |
list_campaigns | GET /v1/my/campaigns | List all campaigns |
create_campaign | POST /v1/my/campaigns | Create a new campaign |
list_contacts | GET /v1/my/contacts | List contacts in your audience |
get_account | GET /v1/my/account | Check account status and limits |
MCP via Gemini CLI is the recommended setup — OAuth sign-in, no API keys to manage. The function calling method is for programmatic use where you need direct API access.
