Hyades

apology-is-policy/hyades

Renders LaTeX math expressions as pure Unicode or ASCII text art that you can paste into terminals, code comments, and plain text files. Exposes a render operation through MCP that takes LaTeX source and returns formatted output, with an optional ASCII-only mode for compatibility. The underlying engine is a native C binary with 95% LaTeX compatibility covering fractions, integrals, matrices, Greek letters, and most standard math notation. Available as both a remote Cloudflare Worker endpoint and a local binary. Useful when you're working with Claude on mathematical content and want properly formatted equations in your terminal or documentation without switching to a rich text editor or PDF viewer.

Install

From registry metadata

$ npx add-mcp https://hyades-mcp.apg.workers.dev/mcp --name hyades

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http hyades https://hyades-mcp.apg.workers.dev/mcp

Run in your terminal. Add --scope user to make it available in every project.

Parameters* required

asciiboolean

Use ASCII-only output instead of Unicode (default: false)default: false

source*string

Complete Hyades document source. Use $$...$$ for display math, $...$ for inline math. Plain text outside math is rendered as prose.

widthinteger

Output width in characters (default: 80). Use 80 for standard terminal width. Avoid going below 60 for complex math.default: 80

Readme

Hyades

LaTeX math as pure Unicode text. For terminals, code comments, emails, and everywhere rich formatting isn't a thing.

Noether's theorem proof rendered entirely as Unicode text in a terminal -- produced by Hyades from standard LaTeX source
_{Every equation above is pure text -- you can select it and copy-paste it anywhere. The source is standard LaTeX.}

What Is This?

Hyades takes standard LaTeX math like this:

$$
  f(x) = \overbrace{\sum_{k=0}^{n} \frac{f^{(k)}(a)}{k!}
           (x-a)^k}^{\mathit{Taylor polynomial}}
       + \underbrace{R_n(x)}_{\mathit{Remainder}}
$$

and renders it as multi-line Unicode text:

             𝑇𝑎𝑦𝑙𝑜𝑟 𝑝𝑜𝑙𝑦𝑛𝑜𝑚𝑖𝑎𝑙
         ╭───────────┴───────────╮
           𝑛      (𝑘)
          ───    𝑓   (𝑎)         𝑘
  𝑓(𝑥) =  ╲     ───────── (𝑥 − 𝑎)  +   𝑅 (𝑥)
          ╱⎽⎽      𝑘!                   𝑛
         𝑘 = 0                       ╰───┬───╯
                                     𝑅𝑒𝑚𝑎𝑖𝑛𝑑𝑒𝑟
