Machfive

bluecraft-ai/machfive-mcp

Connects Claude to MachFive's cold email platform through their remote API. You get six tools: list your campaigns, generate personalized email sequences for single leads (synchronous, takes 3-10 minutes), submit batch jobs for multiple leads, poll batch status, and export results as JSON or CSV. Authentication works three ways: API key in the URL path, Bearer token header, or plain Authorization header. Useful when you want to skip the MachFive web UI and handle lead research, sequence generation, and bulk exports directly from your AI assistant. Runs as a remote server at mcp.machfive.io, so no local installation needed.

Readme

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.
