Coldrig cold-email MCP server
by YS-projectcalc · official
Let your AI set up domains, mailboxes, and cold-email campaigns, then handle replies for you.
Coldrig is a cold-email service that your AI assistant can run for you. Instead of clicking around a website, you tell your AI what you want, and it buys domains, sets up mailboxes, starts campaigns, and sorts through replies. It is handy if you send cold outreach but do not want to manage all the technical pieces yourself.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you. An MCP server is a small helper that gives your AI a new skill or a connection to another service. This one connects your AI to Coldrig, a cold-email platform. Once connected, your AI can look things up and take actions there for you when you ask.
What this MCP server does
You ask your AI to set up or run a cold-email campaign. The AI uses this helper to talk to Coldrig. Coldrig buys domains, creates mailboxes, warms them up, and sends your sequences. When people reply, the AI can pull those replies into a single inbox and help you respond. You get progress updates, results, and reply threads right in your chat.
Click to zoomWhat you can do with it
- Buy branded domains and set up mailboxes
- Start and pause cold-email campaigns
- Check how many emails were sent, opened, or bounced
- Read and reply to responses in one inbox
- Mark threads as read, archived, or labeled
- Add or remove email addresses from a do-not-contact list

Try asking your AI
- “Set up cold-email infrastructure for my brand acme.com with 5 mailboxes.”
- “Launch a campaign called Q3 outreach using my leads list.”
- “Show me all replies from this week and label the interested ones.”
- “How many emails did we send yesterday and how many bounced?”
What it gives back to you
You get back plain answers, lists, and counts in your chat. For example, you might see a list of new replies, a summary of campaign results, or a note that your mailboxes are ready. If you ask it to change something, like pausing a campaign, it tells you that the change was made.
Before you start
What you need
- A Coldrig account (you can start with a free demo)
- A bearer token from Coldrig (a kind of password your AI uses to connect)
- An AI assistant that supports MCP, like Claude Code or Codex
Good to know
This tool can spend real money on domains and mailboxes, and it sends real emails to real people, so be careful with what you ask it to do.
