Generate hyper-personalized cold email sequences via MachFive API.
Connects an assistant to a MachFive account to list campaigns, generate personalized cold email sequences for single leads or batches, and export results.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.Bluecraft-AI%2Fmachfive/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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:
Your AI understands the request, connects to MachFive through MCP, and executes the action — all in seconds.
⚠️ Keep this key private — it's like a password to your MachFive account.

Open your AI assistant and try:
"List my MachFive campaigns"
If you see your campaign list, you're connected! 🎉
MachFive MCP supports three authentication methods:
The Bearer prefix is optional for the Authorization header.
MachFive MCP provides 6 tools for cold email 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..."
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?"
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."
No. Setup takes about 5 minutes and just requires pasting your API key into your AI assistant's settings.
Any MCP-compatible client, including:
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.
Your AI can:
The MCP server is free with your MachFive subscription. Email generation uses your account's credits as normal.

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

List Campaigns
List campaigns in the user's MachFive workspace. CALL THIS FIRST before generate_sequence or generate_batch — you need a campaign ID to generate emails. If the user hasn't specified a campaign, call this and ask them to pick one. Returns JSON array of campaigns with id, name, and created_at. Use the 'id' field as campaign_id in generate calls.
queryGenerate Email Sequence
Generate a personalized cold email sequence for ONE lead. This is SYNCHRONOUS — the request takes 3-10 minutes because MachFive researches the prospect and crafts unique emails. Do NOT retry if it seems slow; wait for the response. You must have a campaign_id first. Call list_campaigns if you don't have one. If the request times out, use the returned list_id with get_list_status and export_list to recover results.
nameemailrequiredtitlecompanylist_namecampaign_idrequiredemail_countlinkedin_urlapproved_ctascampaign_anglecompany_websiteemail_signatureGenerate Batch
Submit multiple leads for batch email sequence generation (ASYNC). Returns IMMEDIATELY with a list_id. Processing runs in the background. After calling this, poll get_list_status every 15-30 seconds until processing_status is 'completed' or 'failed', then call export_list. You must have a campaign_id first. Call list_campaigns if you don't have one.
list_nameleads_jsonrequiredcampaign_idrequiredemail_countapproved_ctascampaign_angleemail_signatureList Lead Lists
List lead lists (batch jobs) in the user's MachFive workspace. Useful for browsing past batches, checking what's in progress, or finding a list_id to export. Results are ordered newest first.
limitoffsetstatuscampaign_idGet List Status
Check the processing status of a lead list. Use this to POLL after calling generate_batch. Call every 15-30 seconds until processing_status is 'completed' or 'failed'. When completed, call export_list. When failed, submit a new batch.
list_idrequiredExport List
Download the generated email sequences for a COMPLETED list. Only call this AFTER get_list_status shows processing_status = 'completed'. If the list is not yet completed, you'll get a 409 error — poll first.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
