MCP server for cold email

The cold email MCP server for AI agents

Connect Claude, ChatGPT, Cursor, Codex or any MCP client: add the server URL and sign in from the client. Your agent quotes domains and mailboxes and sends you the Stripe link, runs warmup, launches campaigns and reads replies. Turn on Prepare orders at sign-in for quotes; in ChatGPT, orders go through the web app.

What is a cold email MCP server?

A remote MCP server that gives an AI agent tools for cold email infrastructure. The Outreach2day MCP server lets Claude, Cursor, Codex and any MCP client with OAuth sign-in check domains, quote domains and mailboxes, run warmup, launch campaigns and read replies, while you approve and pay every order on Stripe. In ChatGPT the assistant checks domains, mailboxes, warmup and campaigns, and orders go through the web app.

Clients

Your agent quotes. You pay.

Payment happens on a Stripe page you open. Your agent prepares the order and you complete it.

01Your agent
Quote
Your agent asks for a quote, priced on our side: domains, mailboxes, monthly and one-off totals. Turn on Prepare orders when you sign in
02You
Confirm
Your agent shows the quote word for word; nothing moves until you say yes in the chat
03You
Pay on Stripe
You pay on a Stripe checkout link; card details stay with Stripe
get_order4 of 4
- Domains registered
- DNS records set
- 12 mailboxes created
- Warmup started
04Your agent
Track the order
Your agent follows the order: domains registered, DNS set, mailboxes created, warmup started

Allowed

Your agent can

Check domains, quote an order and send you the Stripe link
Connect domains you already own and give you the DNS records
Start warmup and tell you when each mailbox is ready
Write and check the sequence, import contacts, launch after 14 days of warmup
Read replies and per-mailbox stats, pause a campaign when you ask, for example when bounces pass 3%
Export warm mailboxes to Instantly or Smartlead after you confirm

Blocked by the server

Your agent cannot

Charge a card: every payment happens on a Stripe page you open
Launch a campaign before its mailboxes have 14 days of warmup and the preflight check passes
Delete domains or mailboxes, cancel your plan or rotate passwords
Show mailbox passwords, SMTP/IMAP credentials or API keys in the chat

Setup

Connect your AI client

Add https://public.outreach2day.com/mcp to your AI client and sign in with your Outreach2day account when it asks. Then ask: "Check my Outreach2day account status". An API key is only for CI and headless setups.

claude.ai, Claude Desktop and mobile

OAuth sign-in

1In claude.ai or Claude Desktop, open Customize, Connectors, click + and choose Add custom connector
2Paste the server URL, https://public.outreach2day.com/mcp, and click Connect
3The first time the client connects, it opens an Outreach2day sign-in page in your browser. Sign in, turn on Prepare orders so the assistant can quote orders and create Stripe checkout links, and allow access
4The connector then works in claude.ai, Claude Desktop and the mobile apps. Remote servers go in as connectors; claude_desktop_config.json is for local servers

Add to Claude

Claude Code

OAuth sign-in

1Add the server with the command below (user scope: every project)
2In Claude Code, run /mcp, pick outreach2day and choose Authenticate. Or run claude mcp login outreach2day
3The first time the client connects, it opens an Outreach2day sign-in page in your browser. Sign in, turn on Prepare orders so the assistant can quote orders and create Stripe checkout links, and allow access
4No browser (CI, a headless box)? Use an API key instead: put it in $OUTREACH2DAY_API_KEY and add --header 'Authorization: Bearer ${OUTREACH2DAY_API_KEY}' to the command (single quotes: Claude Code reads the variable when it connects)

Claude Code docs: MCP

Terminal

claude mcp add --transport http --scope user outreach2day https://public.outreach2day.com/mcp
# then, in Claude Code: /mcp, outreach2day, Authenticate

Codex CLI

OAuth sign-in

1Add the server with codex mcp add, or put the block in ~/.codex/config.toml
2Run codex mcp login outreach2day
3The first time the client connects, it opens an Outreach2day sign-in page in your browser. Sign in, turn on Prepare orders so the assistant can quote orders and create Stripe checkout links, and allow access
4Run codex mcp list to check it

Codex docs: configuration reference

Terminal

codex mcp add outreach2day --url https://public.outreach2day.com/mcp
codex mcp login outreach2day

# or by hand, in ~/.codex/config.toml
[mcp_servers.outreach2day]
url = "https://public.outreach2day.com/mcp"

VS Code

OAuth sign-in

1Click Install in VS Code, or add the block to .mcp.json at the workspace root (~/.copilot/mcp-config.json for every workspace)
2Start the server. VS Code asks you to sign in to Outreach2day
3The first time the client connects, it opens an Outreach2day sign-in page in your browser. Sign in, turn on Prepare orders so the assistant can quote orders and create Stripe checkout links, and allow access
4Open Copilot Chat in agent mode and check the tools list

Install in VS Code

Cursor · Anysphere

OAuth sign-in

Click Add to Cursor, or add an entry with the url to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project). Then open Cursor Settings, MCP, and sign in to outreach2day.

The entry holds only the URL, so mcp.json is safe to commit. Cursor asks before each tool call by default
No browser? Use an API key: "headers": { "Authorization": "Bearer ${env:OUTREACH2DAY_API_KEY}" }. ${env:NAME} is filled from your environment in url and headers; envFile works only for local (stdio) servers

Cursor docs: MCP

~/.cursor/mcp.json

{
  "mcpServers": {
    "outreach2day": {
      "url": "https://public.outreach2day.com/mcp"
    }
  }
}

Add to Cursor

Gemini CLI · Google

OAuth sign-in

gemini mcp add with --transport http and the server URL, then /mcp auth outreach2day to sign in. Add -s user: without it the entry goes to the project's .gemini/settings.json.

In settings.json a streamable HTTP server uses httpUrl; url is for SSE servers
No browser? Add --header 'Authorization: Bearer ${OUTREACH2DAY_API_KEY}' in single quotes; $VAR and ${VAR} expand in headers, so the key stays out of the file
trust: true skips every tool confirmation; leave it off

Gemini CLI docs: MCP servers

Terminal

gemini mcp add -s user --transport http outreach2day https://public.outreach2day.com/mcp
# then, in Gemini CLI: /mcp auth outreach2day

Windsurf · Cognition

OAuth sign-in

Windsurf is now Devin Desktop. Add an entry with serverUrl to ~/.config/devin/mcp_config.json (Windows: %APPDATA%\devin\mcp_config.json), refresh the MCP servers in Cascade and sign in.

Devin Desktop docs: Cascade MCP

mcp_config.json

{
  "mcpServers": {
    "outreach2day": {
      "serverUrl": "https://public.outreach2day.com/mcp"
    }
  }
}

Or set up every client on this computer with one command

$ curl -fsSL https://outreach2day.com/install | sh

PS> irm https://outreach2day.com/install.ps1 | iex

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. Each client asks you to sign in to Outreach2day on first use. View the script

Questions

Or talk to the team

Which AI clients work with it?

Any client that connects to a remote MCP server over streamable HTTP. Add the server URL and sign in to Outreach2day when the client asks: Claude Code, Claude Desktop and claude.ai connectors, ChatGPT developer mode, Codex, Cursor, VS Code with Copilot, Gemini CLI, Windsurf, grok.com connectors and Grok Build. The OpenAI and xAI APIs take an API key in a header, per their docs; we have not tested the APIs against the server yet. The installer adds the server by URL to Claude Code, Cursor, VS Code, Windsurf, Gemini CLI and Codex in one run.

Does the agent need to run the whole setup in one chat?

No. Every call returns the current state and the next step, so you can come back days later and ask where the order or the warmup stands.

Can I limit which tools the agent can call?

Yes. Most MCP clients let you turn single tools on and off, and the xAI and OpenAI APIs take a list of allowed tools. Give a reporting agent only the read tools.

Can the agent spend money on my behalf?

No. The agent can ask for a quote and hand you a Stripe checkout link. You pay on the Stripe page yourself. Quotes are priced by Outreach2day.

Is the Outreach2day MCP server available now?

Yes. Add https://public.outreach2day.com/mcp to your client and sign in to Outreach2day when it asks; turn on Prepare orders if the agent should quote orders. The installer (curl -fsSL https://outreach2day.com/install | sh) sets up Claude Code, Cursor, VS Code, Windsurf, Gemini CLI and Codex on a computer in one run. An API key is only for CI and clients that take only a header.

What does it cost?

The MCP server comes with your Outreach2day account. You pay for what the agent orders: $2.50 per mailbox a month, domains billed yearly, both shown in the quote before you pay.

Which tools does the server have?

Tools for pricing and account status, domains, orders and Stripe checkout, mailboxes and warmup, campaigns, replies and stats, and export to Instantly or Smartlead. The full list is on this page.

Can I use domains I already own?

Yes. The agent connects them and returns the DNS records to set at your registrar. Connecting your own domains is free.

How long until new mailboxes can send?

Full volume, up to 25 cold emails per mailbox a day, from day 14 of warmup. The agent reports each mailbox's warmup stage and ready date, and launches a campaign once its mailboxes have 14 days of warmup.

Can I keep sending from Instantly or Smartlead?

Yes. The agent exports warm mailboxes to your Instantly or Smartlead workspace after you confirm, and you keep your sequences there.

Does the agent see my mailbox passwords?

No. No tool returns passwords, SMTP or IMAP credentials, or API keys. Export to a sequencer is the only step that moves credentials, and it needs your confirmation.

What happens if part of an order fails?

The order shows which domain or mailbox failed, with a link to support. Our team retries or refunds that item.
