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.

• Product page: https://tex64.com/mathpoint (日本語: https://tex64.com/ja/mathpoint)
• Guide: https://mcp.tex64.com/mathpoint/docs
• MCP server: https://mcp.tex64.com/mathpoint/mcp (Streamable HTTP, OAuth sign-in with Google)

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):

   # Mac (Terminal)
   curl -fsSL https://mcp.tex64.com/mathpoint/install | sh
   

   # 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:

   Client	How
   Claude (claude.ai, desktop)	Settings → Connectors → Add custom connector → https://mcp.tex64.com/mathpoint/mcp
   ChatGPT	Settings → Apps & Connectors → create a connector (developer mode) with the same URL
   Claude Code	claude 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
   Codex	codex 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 TeX	Rendering	Figures and tables	Word
PowerPoint equation editor (LaTeX input)	Not needed	Office math	No	Yes
IguanaTex	Required	TeX	If you write them in TeX	No
MathType (paid)	Not needed	MathType	No	Yes
MathPoint	Not needed	TeX (LuaLaTeX)	TikZ, pgfplots, tabularray	Yes

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)

Tools

Tool	What it does	Annotation
list_slides, list_layouts, word_read	Read slides, layouts, and Word paragraphs	read-only
insert_math, word_insert_math	Typeset LaTeX with TeX and insert it (display, inline, or text mode)	write
update_math, word_update_math	Re-typeset a MathPoint shape with new LaTeX, size, or color	write, replaces
render_math	Return typeset math as a PNG without touching any file	read-only
figure_guide, figure_start, figure_requests, figure_build, figure_place, …	Build TikZ / pgfplots figures and tabularray tables, including redraws of sketches and screenshots, then place them	write
set_text, add_text_box, add_slide, move_shape, delete_shape	Edit ordinary PowerPoint text and layout	write
word_insert_text, word_set_text, word_delete	Edit Word paragraphs	write
insert_image, word_insert_image	Place an image as it is	write
select_file, usage	Choose which open file to edit; this month’s usage	—

Edits appear in the open file right away and can be undone with Undo.

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。
