Posylai MCP — AI Email Builder

Build production-ready HTML email campaigns from any brand website.

Posylai MCP lets Claude, Cursor, Codex and other MCP-compatible agents analyze a brand website, build an email design system from it, assemble responsive campaigns, QA the rendering and export production HTML.

Remote MCP endpoint

https://mcp.posylai.ru/mcp

Transport: streamable HTTP. Authentication: personal bearer token.

What it does

Most email tooling starts from a blank template. Posylai starts from the brand's own website: it reads the real markup — typography, palette, spacing rhythm, button shapes, image treatment — and turns it into a reusable master template. Campaigns are then assembled from that template's blocks, so every email looks like the brand instead of like a generic newsletter.

The rendered result is checked before it is handed back: mobile column, alt texts, unsubscribe link, message weight, appearance across mail clients.

Typical timings on our pipeline: ~15 minutes to build a master template from a site, ~10 minutes per campaign after that.

Getting a token

  1. Register at https://posylai.ru/login.html#reg — the password is emailed to you.
  2. Sign in to https://posylai.ru/account/.
  3. Issue an MCP token there.

Tokens are per user, not per server: the endpoint answers nothing without a valid one, and revoking a token in the dashboard takes effect immediately without affecting anyone else.

The first template is free.

Client configuration

Claude Code
claude mcp add --transport http posylai https://mcp.posylai.ru/mcp \
  --header "Authorization: Bearer YOUR_TOKEN"
Claude Desktop, Cursor, VS Code, Codex, Windsurf
{
  "mcpServers": {
    "posylai": {
      "type": "http",
      "url": "https://mcp.posylai.ru/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Per-client file locations are in examples/.

Any client that speaks streamable HTTP MCP with a bearer header will work; there is nothing client-specific in the server.

Typical flow

StepToolWhat happens
1unified_brandsList brands already set up
2unified_brand_design_codeExtract the visual language from a website
3unified_brand_sketchDraft a master template prototype
4unified_brand_createCreate the brand from the prototype
5unified_plan_startAssemble a campaign from a brief
6unified_job_statusPoll until it is ready
7unified_renderRender the email to images
8unified_gatePre-send checks
9unified_exportTake the production HTML

Status tools report progress, so an agent never has to wait blind.

What it does not do

Worth stating plainly so an agent does not plan around it:

  • It does not send campaigns to a list. It returns HTML; sending happens through your ESP — Unisender, Sendsay, Mindbox, Mailganer or any other.
  • It does not store subscribers and does not segment them.
  • It does not invent a visual identity. The style is taken from the brand's site or brand book, not made up.

По-русски

Posylai MCP даёт ИИ-агентам 29 инструментов для сборки email-писем по адресу сайта бренда: снять фирменный стиль, собрать мастер-шаблон, сформировать письмо по заданию, проверить вёрстку и забрать готовый HTML.

Адрес сервера — https://mcp.posylai.ru/mcp, транспорт streamable HTTP, авторизация личным токеном. Токен выпускается в личном кабинете после регистрации; первый шаблон бесплатный.

Токен привязан к учётной записи: без действующего токена сервер не отвечает. Отозвать его можно в кабинете, старый перестаёт работать сразу.

Сервер не рассылает письма по базе и не хранит подписчиков — он отдаёт готовый HTML, а отправка идёт через ваш сервис рассылок. Подробная документация на русском: https://posylai.ru/mcp/
