Overview

AI-generated overview

MathPoint typesets LaTeX equations, TikZ figures and tables with real TeX and inserts them into the PowerPoint or Word file you have open.

What you can do
  • Read slides, layouts and Word paragraphs in the open file
  • Typeset LaTeX and insert display, inline or text-mode math into slides or Word
  • Re-typeset existing MathPoint shapes with new LaTeX, size or color
  • Build TikZ/pgfplots figures and tabularray tables, including redraws of sketches, then place them
  • Edit ordinary PowerPoint text, text boxes, slides and shapes, and Word paragraphs
  • Render math as a PNG without touching any file, and check monthly usage
When to use it
Useful when you write math-heavy slide decks or Word documents and want equations, plots or tables produced from chat instead of installing TeX or hand-placing images. It also suits users who want TeX-quality output in PowerPoint for the web.
Requirements
A remote Streamable HTTP endpoint with OAuth sign-in through Google. The MathPoint add-in must be installed in PowerPoint or Word (Microsoft 365 or Office 2021 and later) and its task pane kept open on the file you want edited. No local TeX install is needed.
Before you install
The server can write to and delete content in the open presentation or document, though edits can be undone. Slide and document content passes through the server when the AI reads it, and TeX sources and results are kept for up to 30 days. The free plan covers 30 items a month; a paid plan is planned. Sign-in uses a Google account.

Installation

In SourceWeft

  1. Open MathPoint in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Fermion-company%2Fmathpoint/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

MathPoint — LaTeX equations in PowerPoint and Word, no TeX install

MathPoint is an add-in for Microsoft PowerPoint and Word that puts LaTeX equations, TikZ / pgfplots figures, and tables typeset with real TeX into the slide deck or document you have open. Type LaTeX in its task pane, or ask Claude or ChatGPT in chat. Typesetting runs on the MathPoint server with LuaLaTeX, so you do not need TeX installed, and it works in PowerPoint for the web too.

This repository holds the public connection details: the Claude plugin, the MCP Registry entry, and this README. The MathPoint service itself is operated by Fermion Inc.

Get started

  1. Install the add-in (PowerPoint and Word, Microsoft 365 or Office 2021 and later):

    sh
    # Mac (Terminal)curl -fsSL https://mcp.tex64.com/mathpoint/install | sh
    powershell
    # Windows (PowerShell)irm https://mcp.tex64.com/mathpoint/install.ps1 | iex

    On the web, use Add-ins → More Add-ins → My Add-ins → Upload My Add-in and choose manifest.prod.xml.

  2. Sign in. Reopen PowerPoint or Word, open Home → Add-ins → MathPoint, and sign in with Google in the task pane.

  3. Connect your AI. Choose Claude or ChatGPT in the task pane, or add the MCP server yourself:

    ClientHow
    Claude (claude.ai, desktop)Settings → Connectors → Add custom connector → https://mcp.tex64.com/mathpoint/mcp
    ChatGPTSettings → Apps & Connectors → create a connector (developer mode) with the same URL
    Claude Codeclaude mcp add --transport http mathpoint https://mcp.tex64.com/mathpoint/mcp, or install this plugin: /plugin marketplace add Fermion-company/mathpoint-plugin then /plugin install mathpoint@mathpoint
    Codexcodex mcp add mathpoint --url https://mcp.tex64.com/mathpoint/mcp

  4. Ask. Keep the task pane open and ask in chat.

Use it without an AI

Like IguanaTex, MathPoint works on its own: open the task pane, type LaTeX, check the live preview, and click Insert. TikZ code and tables copied from Excel go in the same way. The LaTeX source is stored with the shape, so you can open it again and re-typeset.

How it compares

Local TeXRenderingFigures and tablesWord
PowerPoint equation editor (LaTeX input)Not neededOffice mathNoYes
IguanaTexRequiredTeXIf you write them in TeXNo
MathType (paid)Not neededMathTypeNoYes
MathPointNot neededTeX (LuaLaTeX)TikZ, pgfplots, tabularrayYes

IguanaTex is a VBA add-in, so it does not run in PowerPoint for the web; MathPoint does.

A longer comparison: How to use LaTeX equations in PowerPoint: five ways compared.

Example prompts

  • “Put the quadratic formula on slide 2.”
  • “Make the equations on slide 2 teal and a bit larger.”
  • “Add a slide with a 3D surface plot of a bivariate Gaussian.”
  • “Redraw this hand-drawn circuit as a clean figure and put it on slide 3.”
  • “Turn this table into a booktabs-style table with the decimals aligned.”
  • “In my Word document, add Euler’s identity after paragraph 3, and make a ≠ 0 in the text inline math.”
  • “Typeset Maxwell’s equations and show me the image.” (works without Office)

Plans

The free plan covers 30 typeset equations, figures, or tables a month (re-typesetting the same item does not count again). A paid plan without a monthly limit (600 JPY a month, tax included) is on the way.

Privacy

Full policy: https://mcp.tex64.com/mathpoint/privacy. In short:

  • MathPoint can edit only files where the MathPoint task pane is open.
  • Slide and document content passes through the server only when your AI reads it; it is not stored.
  • TeX sources and typeset results are kept for up to 30 days for your work.
  • Sign-in uses Google. You can disconnect AI apps or delete your account at any time from https://mcp.tex64.com/mathpoint/account.

日本語

MathPoint は PowerPoint と Word に LaTeX の数式・TikZ の図・表を入れるアドインです。 作業ウィンドウに LaTeX を打つか、Claude や ChatGPT にチャットで頼むと、TeX で組んだ 結果が開いているスライドや文書に入ります。組版はサーバーで行うので、TeX の インストールは要りません（IguanaTex と違い、Web 版の PowerPoint でも動きます）。

  1. Mac はターミナルで curl -fsSL https://mcp.tex64.com/mathpoint/install | sh、 Windows は PowerShell で irm https://mcp.tex64.com/mathpoint/install.ps1 | iex を実行します。
  2. PowerPoint を開き直し、ホーム → アドイン → MathPoint を開いて Google でログインします。
  3. 作業ウィンドウから Claude か ChatGPT をつなぎ、「スライド 2 に二次方程式の解の公式を入れて」のように頼みます。

無料プランは月 30 件までです。詳しくは https://tex64.com/ja/mathpoint をご覧ください。
