PopNx MCP 的三大支柱

这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

  • 连接方式: 在云端运行
  • 传输方式: Streamable HTTP
  • 分类: 文档、表格与办公
  • 你需要填写:Authorization

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

你需要

你用的是哪个应用?

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。

这个地址需要在请求的 header 中放入密钥,而添加连接器的菜单无法设置。请改用 Claude Code、Cursor 或 VS Code。

在终端中运行这条命令

claude mcp add --transport http unplain https://app.unplain.io/api/mcp --header 'Authorization: your-value'

运行前请先填写空着的值。

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "unplain": {
      "url": "https://app.unplain.io/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

在 VS Code 中打开

或者自己复制设置

粘贴到项目中的 .vscode/mcp.json

{
  "servers": {
    "unplain": {
      "type": "http",
      "url": "https://app.unplain.io/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

这个地址需要在请求的 header 中放入密钥,而添加连接器的菜单无法设置。请改用 Claude Code、Cursor 或 VS Code。

你的选择通过 Cookie 保存在这台设备上,无需账户。

需要你填写的值

  • Authorization 机密 必填 HTTP header
    Your Unplain API key, as 'Bearer unp_...'. Create one at https://app.unplain.io/account under API keys. A bare key without the 'Bearer ' prefix is also accepted.

这些设置是根据作者在注册中心的条目生成的。如果 README 的写法不同,请以 README 为准。

常见问题

Unplain 安全吗?

它在 1 项适用的基础检查中通过了 1 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

你需要填写:Authorization

它在我的电脑上运行还是在云端?

它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(1.0.1)于3个月前进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

Unplain MCP

Your assistant writes the ebook or report. Unplain designs it and hands back a publish-ready PDF.

Unplain is a hosted Model Context Protocol server. Ask for a document and your assistant writes it, picks a design (or applies a brand you have saved), generates a cover, and exports a finished PDF with a composed cover, a table of contents built from the headings, real pagination and a closing call-to-action page. You never leave the chat, and you never open a design tool.

Two things follow from that, and they are the reason to use this rather than asking a model for a PDF directly:

  • It comes out the same every time. Brand Themes are stored, so the tenth document matches the first. Your assistant can create one and reuse it.
  • Revisions cost no tokens. Every document is a real project in your Unplain account, and the tools return an editor link. Fix a sentence by clicking it, not by asking the model to regenerate the file.

Unplain does not write your content, and through MCP it does not take file uploads: your assistant supplies the words as Markdown. Uploading a .docx or a .txt is a web app feature, not an MCP one.

  • Endpoint: https://app.unplain.io/api/mcp
  • Transport: Streamable HTTP
  • Auth: Authorization: Bearer (a bare Authorization: is also accepted)
  • Install: nothing to install
  • Docs: https://unplain.io/mcp
  • Pricing: included on every plan, free and Pro. https://unplain.io/pricing

This repository is documentation. The server is hosted, so there is no package

to install and no source to run. Issues and questions are welcome here.

Publishing to the official MCP Registry: see PUBLISHING.md.

The manifest is server.json.


Quick start

1. Get an API key

Create one at account settings. It is shown once. A free account works for everything below.

2. Add the server

Claude Code

claude mcp add --transport http unplain https://app.unplain.io/api/mcp \

--header "Authorization: Bearer unp_your_key_here"

Full guide: https://unplain.io/mcp/claude-code

Codex

export UNPLAIN_API_KEY="unp_your_key_here"

codex mcp add unplain \ --url https://app.unplain.io/api/mcp \ --bearer-token-env-var UNPLAIN_API_KEY

Full guide: https://unplain.io/mcp/codex

Anything else

Any client that can add a remote MCP server and send an Authorization header works. You need two values:

Server URL:  https://app.unplain.io/api/mcp

Header: Authorization: Bearer unp_your_key_here

A client that only supports servers running on your own machine cannot connect yet.

3. Say hello
List the Brand Themes in my Unplain account and tell me which one is the default.

An empty list is still a success: the connection is live, you have not saved a theme yet.

4. Make something
Write a short ebook called "The Email Welcome Sequence Playbook" with an intro

and five chapters. Use my default Brand Theme, then export the PDF.


Tools

Twelve tools. Names and behaviour are current as of the version in CHANGELOG.md.

ToolWhat it does
get_accountReport the plan this key belongs to and the limits that apply. Worth calling before writing anything long.
get_design_optionsThe font catalog, the built-in presets, and the allowed range of each typography and spacing setting.
list_brand_themesList saved Brand Themes.
create_brand_themeSave a new Brand Theme: colors, fonts, links.
update_brand_themeChange a theme's name, colors, fonts or links.
create_ebookCreate a project from a title and Markdown.
list_ebooksFind the caller's projects.
get_ebookRead a project back as a structured outline.
update_ebookRewrite paragraphs, headings and lists, change cover copy and style, apply a theme, or replace the body.
generate_cover_imageAI cover artwork, drawn from the section headings or from your direction.
export_ebookRender the designed PDF.
get_export_statusPoll a running export and get the download link.
Notes that matter in practice
  • Edits are atomic and version-checked. An assistant cannot overwrite a change you made in the web app in the meantime; a stale write is rejected rather than applied over your work.
  • Design can be described rather than specified. "A stark monochrome report" or "an elegant independent literary journal" resolves to real settings, chosen from what Unplain actually supports rather than guessed.
  • Fonts outside the catalog are refused, not substituted. What you see in the app is what lands in the PDF.
  • Cover generation uses your existing allowance, the same one the button in the app draws on. There is no separate MCP allowance. Overwriting an existing cover needs an explicit go-ahead, so a repeated request cannot silently spend a second generation.
  • Download links are signed and expire. The project is saved, so export again rather than hoarding the URL.

Plans and limits

The MCP is an interface, not a tier. A key carries exactly the capabilities of the account behind it, and the same limits apply whether you work in the web app or through an assistant.

Example prompts

See examples/prompts.md for a fuller set. A few to start:

Take the Markdown in notes.md and create an Unplain ebook called "Q3 Growth

Report". Use my default Brand Theme, then wait for the export and give me the PDF link.

Open my Unplain ebook "Q3 Growth Report", read the outline, rewrite the introduction so it opens with a concrete number instead of a general claim, then export a fresh PDF.

Analyse the churn data in ./data, write it up as a report with an executive summary, three findings and a recommendation, then create it in Unplain using my "Acme" theme and export the PDF.


Keeping your key safe

Treat it like a password.

  • Codex reads it from an environment variable, which keeps it out of config files.
  • Claude Code's -s project writes a .mcp.json in the project root. Do not commit a real key in it. Use a placeholder and have each person supply their own; a key acts in the account it belongs to.
  • Revoke from account settings. Revocation takes effect immediately. Keep one key per client so you can revoke one without disturbing the rest.

Troubleshooting

SymptomCause
Every tool call failsThe key is not reaching the server. The header must be Bearer (with the space) then the key, and the URL must end in /api/mcp with no trailing slash. A bad key returns 401, which most clients report as a failed connection.
Tools do not appearRestart the client. New servers are picked up at session start.
Codex cannot find the keyIt reads the environment at launch. Export it in your shell profile and start Codex from a shell that has it.
"No Brand Themes"The connection works, you have not saved one. Your assistant can create one, or design from the built-in presets.
Export says the ebook is too longFree exports up to 5 content pages. Shorten it or upgrade. The project is saved either way.
Too many requestsPer-account rate limits on creates and exports. Wait a minute.
