MCP server and API

Set up cold email from Claude, Cursor or Codex

One command connects your AI assistant to Outreach2day: it checks domains, quotes mailboxes, you approve and pay on Stripe, it sets up DNS, warm-up and campaigns.

MCP server

Three steps, one command

  1. Run the command. It finds the AI clients on your computer and adds the Outreach2day server
  2. Sign in from your client. The first time it connects, the client opens an Outreach2day sign-in page. Turn on Prepare orders there so the assistant can quote orders. No API key to copy
  3. Ask your assistant. Start with “Check my Outreach2day account status”. It quotes every order; you approve and pay on Stripe
Setup and prompts for Claude, ChatGPT, Grok and CursorSetup steps
curl -fsSL https://outreach2day.com/install | sh

It adds the server by URL to Claude Code, Cursor, VS Code, Windsurf, Gemini CLI and Codex, and prints the connector steps for Claude Desktop, after a backup of each config. No API key: each client asks you to sign in on first use. View the script
