How to Set Up and Use Hyades

Hyades is a Unicode and ASCII mathematical typesetting engine that accepts LaTeX-style math input and renders it into human-readable Unicode or ASCII representations suitable for source code comments, terminals, and plain-text documentation. It ships with an MCP server that lets AI assistants like Claude invoke the typesetting engine directly, a VSCode-compatible language server for real-time math rendering in editors, and a document processor called cassilda for rendering entire notebook files. Developers and scientists use Hyades to embed beautifully formatted math into code comments and documentation without needing a full LaTeX toolchain.

Prerequisites

  • A C build toolchain (cmake) for building from source, or pre-built binaries from the Releases page
  • Helix or Neovim for automatic editor integration (optional)
  • Claude CLI (claude) installed if using the remote MCP server via Cloudflare
  • An MCP-compatible client such as Claude Desktop for the MCP server integration
1

Download and install the pre-built binary

Download the release for your platform from GitHub Releases, then run the installer script which places hyades and cassilda in the correct system path.

# Linux/macOS
chmod a+x install.sh
./install.sh

# Windows (PowerShell)
.\install.ps1
2

Build from source (alternative)

Build hyades and cassilda from source using cmake if you prefer or need a custom build.

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build
3

Test the typesetting engine on the command line

Pipe LaTeX math to hyades to see Unicode output, or use --ascii for ASCII-only terminals.

echo '$$\sum_{i=1}^n i^2$$' | hyades
echo '$$\int_0^1 f(x) dx$$' | hyades --ascii
hyades equations.hy
4

Add the remote MCP server via Claude CLI

Connect the hosted Cloudflare Worker MCP server to Claude using the mcp add command.

claude mcp add hyades --transport http https://hyades-mcp.apg.workers.dev/mcp
5

Add the local MCP server using the native binary

Alternatively, use your locally installed hyades-mcp binary for the MCP server.

claude mcp add hyades /path/to/hyades-mcp
6

Render a cassilda notebook document

Use the cassilda tool to process or render full .cld notebook files section by section.

cassilda render notebook.cld section_name
cassilda process notebook.cld

Hyades Examples

Client configuration

Add the Hyades MCP server to Claude Desktop using the remote Cloudflare endpoint.

{
  "mcpServers": {
    "hyades": {
      "type": "http",
      "url": "https://hyades-mcp.apg.workers.dev/mcp"
    }
  }
}

Prompts to try

Example requests once hyades is connected as an MCP server.

- "Render this LaTeX expression as Unicode: $$\\sum_{i=1}^{n} i^2 = \\frac{n(n+1)(2n+1)}{6}$$"
- "Convert $$\\int_0^\\infty e^{-x^2} dx = \\frac{\\sqrt{\\pi}}{2}$$ to ASCII art for a code comment"
- "Typeset the quadratic formula and add it as a comment to my Python function"
- "Render the Fourier transform definition in Unicode for documentation"

Troubleshooting Hyades

install.sh reports permission denied or binary not in PATH

The installer places binaries in $HOME/.local/bin on Unix. Add this directory to your PATH: `export PATH="$HOME/.local/bin:$PATH"` in your shell profile.

cmake build fails with missing compiler error

Install the required C build tools. On Ubuntu/Debian: `sudo apt install cmake build-essential`. On macOS: `xcode-select --install` then install cmake via Homebrew with `brew install cmake`.

Remote MCP server at hyades-mcp.apg.workers.dev is unreachable

Fall back to the local binary option: build hyades from source and add it as a local MCP server with `claude mcp add hyades /path/to/hyades-mcp`.
