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:

document matches the first. Your assistant can create one and reuse it.

  • It comes out the same every time. Brand Themes are stored, so the tenth

account, and the tools return an editor link. Fix a sentence by clicking it, not by asking the model to regenerate the file.

  • Revisions cost no tokens. Every document is a real project in your Unplain

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:
  • Pricing: included on every plan, free and Pro.

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:

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:

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.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
