Questions

MachFive MCP Server

What is MachFive MCP Server?

MCP (Model Context Protocol) is an open standard that lets AI assistants like Claude connect to external apps. Think of it as a universal translator between AI and software.

MachFive MCP Server is a connector that lets your AI assistants communicate directly with your MachFive account. Your AI can list campaigns, generate hyper-personalized cold email sequences, manage lead lists, and export results — all through natural conversation.

Instead of logging into MachFive, uploading CSVs, and waiting for results, you can simply tell your AI what you need:

"Generate a 3-email sequence for [email protected] using my SaaS Founders campaign"
"Show me my MachFive campaigns"
"Submit these 50 leads for batch processing"
"Check the status of my latest batch and export the results"

Your AI understands the request, connects to MachFive through MCP, and executes the action — all in seconds.

How to Set Up MachFive MCP

Step 1: Get Your API Key (2 min)

Log in to your MachFive account at app.machfive.co
Go to Settings → API Keys
Click Create API Key
Copy your key and store it securely

⚠️ Keep this key private — it's like a password to your MachFive account.

Step 2: Connect Your AI Client

Option A: Claude Desktop (Easiest)

Open the Claude Desktop app
Go to Settings → Connectors
Click Add custom connector
Enter:
- Name: MachFive
- Remote MCP server URL: https://mcp.machfive.co/mcp/YOUR_API_KEY
Replace YOUR_API_KEY with the API key you created
Click Add — no restart needed!

Option B: Claude Desktop (Config File)

If you prefer editing the config file directly:

Go to Settings → Developer → Edit Config
Add this to your config file (replace YOUR_API_KEY):

{
  "mcpServers": {
    "machfive": {
      "url": "https://mcp.machfive.co/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Save and restart Claude Desktop

Option C: Cursor

Open Cursor → Settings (⌘ + ,)
Search for MCP
Click Edit in settings.json
Add the following (replace YOUR_API_KEY):

{
  "mcpServers": {
    "machfive": {
      "url": "https://mcp.machfive.co/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Save and restart Cursor

Option D: n8n (AI Agents & Workflows)

For automating workflows with AI agents in n8n:

Add the MCP Client node to your workflow
Select Streamable HTTP as the transport option
Enter the URL: https://mcp.machfive.co/mcp/YOUR_API_KEY
Connect to your AI agent node

Option E: Other MCP Clients

For any MCP-compatible client, use the URL with your API key:

https://mcp.machfive.co/mcp/YOUR_API_KEY

This URL works with any client that supports Streamable HTTP transport.

Step 3: Test It! (30 sec)

Open your AI assistant and try:

"List my MachFive campaigns"

If you see your campaign list, you're connected! 🎉

Authentication

MachFive MCP supports three authentication methods:

Method	Format	Best For
URL path	`https://mcp.machfive.co/mcp/YOUR_API_KEY`	Clients without header support, n8n
Authorization header	`Authorization: Bearer YOUR_API_KEY`	Claude Desktop, Cursor

The Bearer prefix is optional for the Authorization header.

Example Conversations

Quick Single Lead Generation

You: "Generate a 3-email sequence for [email protected] using my Marketing Agencies campaign. Her name is Jane Doe and she's the VP of Growth."

AI: "I'll generate that sequence now. This typically takes 3-5 minutes since MachFive researches the prospect and crafts personalized emails..."

[3 minutes later]

AI: "Here's your 3-email sequence for Jane Doe at Acme:

Email 1 — Subject: Quick question, Jane Hi Jane, I noticed Acme's recent expansion into..."

Batch Processing Workflow

You: "I have 25 leads to process. Here they are: [paste leads]. Use my SaaS Founders campaign."

AI: "Batch submitted! I got list ID abc-123. Let me check the status..."

[polls automatically]

AI: "Your batch is complete — all 25 leads processed with 75 emails generated. Would you like me to export as CSV or JSON?"

Morning Workflow Check

You: "What campaigns do I have, and are there any batches still processing?"

AI: "You have 3 campaigns: First Campaign, Gator 100, and Marketing Agencies. All current batches are completed — no pending jobs."

Troubleshooting

Problem	Solution
Connection failed	Double-check your API key is correct
"Invalid API key" error	Regenerate your API key in MachFive settings
No response	Restart your AI client
Timeout on generate_sequence	Normal — generation takes 3-10 minutes. Don't retry.
Server unavailable	Check your internet connection and try again

Frequently Asked Questions

1. Do I need to know how to code?

No. Setup takes about 5 minutes and just requires pasting your API key into your AI assistant's settings.

2. Which AI assistants work with this?

Any MCP-compatible client, including:

Claude Desktop (Anthropic)
Cursor (AI code editor)
n8n (AI agent workflows)
Any app supporting Streamable HTTP transport

3. Is my data safe?

Yes. The connection uses your personal API key over encrypted HTTPS. Your AI can only access what your API key permits. Each user authenticates with their own key — MachFive never stores or shares API keys on the MCP server.

4. What can my AI do with MachFive?

Your AI can:

List your campaigns
Generate personalized cold email sequences for individual leads
Submit batches of leads for bulk generation
Check batch processing status
Export completed results as CSV or JSON

5. How much does it cost?

The MCP server is free with your MachFive subscription. Email generation uses your account's credits as normal.

6. What's the connection URL?

https://mcp.machfive.co/mcp

7. How long does email generation take?

Single lead generation (generate_sequence) takes 3-10 minutes because MachFive researches the prospect and crafts truly personalized emails. Batch generation (generate_batch) returns immediately — processing happens in the background, and you poll for completion.

8. What if something goes wrong?

Generation is non-destructive — it creates new email sequences without affecting existing data. If a batch fails, simply submit a new one.
