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 jane@acme.com 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)
  1. Log in to your MachFive account at app.machfive.co
  2. Go to Settings → API Keys
  3. Click Create API Key
  4. 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)
  1. Open the Claude Desktop app
  2. Go to Settings → Connectors
  3. Click Add custom connector
  4. Enter:
  • Name: MachFive
  • Remote MCP server URL: https://mcp.machfive.co/mcp/YOUR_API_KEY
  1. Replace YOUR_API_KEY with the API key you created
  2. Click Add — no restart needed!
Option B: Claude Desktop (Config File)

If you prefer editing the config file directly:

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

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

  1. Save and restart Claude Desktop
Option C: Cursor
  1. Open Cursor → Settings (⌘ + ,)
  2. Search for MCP
  3. Click Edit in settings.json
  4. Add the following (replace YOUR_API_KEY):
{

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

  1. Save and restart Cursor
Option D: n8n (AI Agents & Workflows)

For automating workflows with AI agents in n8n:

  1. Add the MCP Client node to your workflow
  2. Select Streamable HTTP as the transport option
  3. Enter the URL: https://mcp.machfive.co/mcp/YOUR_API_KEY
  4. 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:

MethodFormatBest For
URL pathhttps://mcp.machfive.co/mcp/YOUR_API_KEYClients without header support, n8n
Authorization headerAuthorization: Bearer YOUR_API_KEYClaude Desktop, Cursor
Authorization header (no prefix)Authorization: YOUR_API_KEYSimplified integrations

The Bearer prefix is optional for the Authorization header.

Available Tools

Example Conversations

Quick Single Lead Generation

You: "Generate a 3-email sequence for jane@acme.com 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

ProblemSolution
Connection failedDouble-check your API key is correct

No responseRestart your AI client
Timeout on generate_sequenceNormal — generation takes 3-10 minutes. Don't retry.
Server unavailableCheck 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.
