Overview

Description from the maker (original English)

Warm up mailboxes, check the ready-for-outbound gate, run cold email and get checkout links.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Online shops & payments
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http emailwarmup https://app-emailwarmup.bobwork.ai/mcp --header 'Authorization: Bearer {api_key}'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "emailwarmup": {
      "url": "https://app-emailwarmup.bobwork.ai/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "emailwarmup": {
      "type": "http",
      "url": "https://app-emailwarmup.bobwork.ai/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret required HTTP header
    BobWork Email Warm-up API key (bwk_...). An agent can get one with no browser: POST https://app-emailwarmup.bobwork.ai/api/v1/signup/code then /signup/verify.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • get_account

    Your account: email, credit balance, free mailbox allowance (10, or 20 for accounts created before 27 October 2026, plus referral bonus), paid extras and your referral link.

  • list_mailboxes

    Every connected mailbox with warm-up day, status, 7-day spam rate, today's and last 7 days' numbers, and whether it is ready for outbound.

  • get_mailbox

    One mailbox's warm-up status and health.

  • mailbox_activity

    The last 100 warm-up events for a mailbox (sent, received, replied, rescued from spam, errors).

  • warmup_stats

    Totals across your mailboxes: today and last 7 days (sent, received, rescued, replied), active and ready counts.

  • list_providers

    IMAP/SMTP presets (Gmail app password, Yahoo, iCloud, Zoho, Lark, SES, SendGrid, Mailgun…) with hosts and ports, plus the Google and Zoho API routes.

  • connect_imap_mailbox

    Connect any mailbox with IMAP + SMTP. The login is tested before it is saved. Use an app password when two-factor sign-in is on. Give a preset (see list_providers) or the hosts. Warm-up starts the same day.

  • connect_zoho_mailbox

    Connect a Zoho Mail mailbox through the Zoho API (works on Zoho's free plan). Needs a Self Client id, secret and a generated code from api-console.zoho.com.

  • google_connect_link

    Get a link the user opens to connect Gmail / Google Workspace with Google sign-in (one click, any device). The mailbox appears in list_mailboxes a few minutes after they allow it.

  • update_mailbox

    Change a mailbox's display name, daily warm-up cap (1-100, null = default), time zone (IANA, e.g. Europe/London) or the signature added to its warm-up mail (empty = default: full name and company).

  • pause_mailbox

    Pause warm-up for a mailbox.

  • resume_mailbox

    Resume warm-up for a mailbox.

  • test_mailbox

    Sign in to the mailbox now and report whether the stored login still works.

  • remove_mailbox

    Remove a mailbox and delete its stored login. Irreversible: ask the user first, then pass confirm=true.

  • set_pool_mode

    Shared network (default: warm with every mailbox on the service) or private pool (only your own mailboxes write to each other; needs 2+).

  • set_warm_style

    Teach warm-up mail how you write: paste up to 4,000 characters of your own sent emails (tone, length, sign-offs). Empty clears it. Used when the AI writes your warm-up conversations.

  • list_workspaces

    Client workspaces (agencies): each client's mailboxes are kept separate under one login and one bill. Returns id, name and mailbox count. Each mailbox in list_mailboxes has a workspace id (null = My mailboxes).

  • create_workspace

    Create a client workspace, e.g. the client's company name (max 100 per account).

  • rename_workspace

    Rename a client workspace.

  • delete_workspace

    Delete a client workspace. Its mailboxes are NOT deleted: they move back to My mailboxes and keep warming. The client's report link stops working.

  • move_mailbox_to_workspace

    Put a mailbox in a client workspace. Leave workspace_id out (or empty) to move it back to My mailboxes.

  • get_workspace_report

    The public read-only report link for one client workspace (mailbox health, spam rate, SPF/DKIM/DMARC). The client opens it without a login; it shows no prices and nothing about other clients.

  • domain_health

    SPF, DKIM selector, DMARC policy and MX for every domain you have connected.

  • check_spf

    Look up a domain's SPF record.

  • check_dkim

    Find a domain's DKIM key: tries the selector you give, selectors seen in real mail, then 45 common ones.

  • check_dmarc

    Look up a domain's DMARC record and policy.

  • get_credits

    Prepaid credit balance, prices and recent charges (Outbound emails, AI drafts).

  • list_campaigns

    Your Outbound campaigns with status and stats.

  • get_campaign

    One campaign: its emails, mailboxes, stats and time left.

  • create_campaign

    Create a draft Outbound campaign (nothing is sent). Emails can use {first_name}, {company} and any contact field. Any connected mailbox can send; one that is still warming shows a warning first.

  • update_campaign

    Edit a paused or draft campaign. Fields you leave out keep their value.

  • add_contacts

    Add up to 1,000 contacts to a campaign. Each needs email; other fields (first_name, company…) fill the placeholders. Duplicates and unsubscribed addresses are skipped.

  • list_campaign_contacts

    Contacts in a campaign and where each is in the sequence (first 200).

  • start_campaign

    Start or resume a campaign. This SENDS real email and uses credits. Confirm with the user first. accept_sending_rules=true means the user agrees to https://emailwarmup.bobwork.ai/terms#outbound-beta (only people who may receive it, honest sender, unsubscribe honoured). If a chose

  • pause_campaign

    Pause a running campaign.

  • get_billing_status

    Payment status after you gave the user a checkout link: credit balance, whether the extra-mailbox subscription is active, mailboxes vs the free limit, and checkouts still waiting for payment. Confirms a paid checkout straight away.

  • create_billing_checkout

    Get a Stripe Checkout url for extra mailboxes beyond the free limit (monthly, or yearly = 10 months' price for 12). The USER opens it and pays; you cannot. Then poll get_billing_status. Returns already:true when the account is subscribed. Prices come back in the result (prices).

  • create_credits_checkout

    Get a Stripe Checkout url to top up prepaid credits for Outbound sending and AI drafts (one-off $5, $10, $25 or $100; credits never expire). The USER opens it and pays; you cannot. Then poll get_billing_status.

  • list_bought_domains

    Domains bought in the domain shop, their hosted mailboxes, renewal date and price, plus IMAP/SMTP settings.

  • search_domains

    Find available lookalike domains for cold email, with first-term and renewal prices.

  • buy_domains

    Buy domains with up to 3 mailboxes each. Returns a Stripe checkout link for the person to pay; setup starts once paid. Needs accept_sending_rules true.

  • add_hosted_mailboxes

    Add mailboxes to a domain you bought here ($3 per mailbox per month). Returns a Stripe checkout link.

  • hosted_mailbox_login

    Password, IMAP and SMTP settings for one of your hosted mailboxes.

  • list_dns_records

    DNS records on a domain you bought here.

  • add_dns_record

    Add a DNS record to a domain you bought here. name = subdomain ('' for the domain itself). Types A, AAAA, CNAME, ALIAS, MX, TXT, CAA, SRV.

  • delete_dns_record

    Delete a DNS record by id (from list_dns_records). Deleting MX, SPF, DKIM or DMARC stops the mailboxes working.

Common questions

Is Emailwarmup safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

BobWork Email Warm-up MCP server

Remote MCP server for BobWork Email Warm-up: warm up any mailbox (Gmail, Google Workspace, Microsoft 365, Zoho, or any IMAP/SMTP), read inbox placement and spam rate, check SPF/DKIM/DMARC, and run cold email campaigns from your own mailboxes. Built so an AI agent can do the whole job for its human: sign up, connect mailboxes, start sending, and get a checkout link when payment is needed.

This repository holds the docs and the registry file. The server itself is hosted, so there is nothing to install or run.

  • Endpoint: https://app-emailwarmup.bobwork.ai/mcp (Streamable HTTP)
  • Auth: Authorization: Bearer bwk_...
  • REST API: https://app-emailwarmup.bobwork.ai/api/v1 (OpenAPI)
  • Agent guide: llms-full.txt

Get an API key with no browser

An agent can create the account for its human. The human only has to read one code from their inbox.

curl -X POST https://app-emailwarmup.bobwork.ai/api/v1/signup/code \

-H "Content-Type: application/json" -d '{"email": "you@company.com"}'

-> {"nonce": "..."}; a 6-digit code is emailed to you@company.com

curl -X POST https://app-emailwarmup.bobwork.ai/api/v1/signup/verify \ -H "Content-Type: application/json" -d '{"nonce": "...", "code": "123456"}'

-> {"api_key": "bwk_..."} (shown once)

Or sign in at https://app-emailwarmup.bobwork.ai/login and create a key under API.

Add it to your client

Claude Code:

claude mcp add --transport http email-warmup https://app-emailwarmup.bobwork.ai/mcp \

--header "Authorization: Bearer bwk_YOUR_KEY"

Pricing

  • Warm-up: free for up to 10 mailboxes, no credit card. Extra mailboxes are billed per mailbox per month, cheaper at volume; yearly billing is 10 months for 12. Current prices: https://emailwarmup.bobwork.ai/pricing
  • Cold email: $2 per 1,000 emails sent, from prepaid credits ($10, $25, $100 packs).
  • When payment is needed, the API and MCP tools return a Stripe checkout link for the human to open, and get_billing_status confirms it went through.
