Machfive MCP Server

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.

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."

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.io/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.
