## What it does

Hyades parses mathematical notation from LaTeX and prints it as readable formatted text. The engine handles fractions, sums, integrals, and matrices. Output behaves like standard text, so copying it into plain buffers works immediately.

When Unicode support is missing, the tool switches to plain ASCII characters. Connecting through the MCP protocol relies on an HTTP endpoint at `https://hyades-mcp.apg.workers.dev/mcp` without needing a local native C compilation.

## Requirements
- Remote server: `https://hyades-mcp.apg.workers.dev/mcp`

## Install

### Claude Code (native platform)

**Platform CLI: remote server**
```bash
claude mcp add --transport http hyades https://hyades-mcp.apg.workers.dev/mcp
```

### Codex

**Platform CLI: remote server**
```bash
codex mcp add hyades --url https://hyades-mcp.apg.workers.dev/mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "hyades": {
            "url": "https://hyades-mcp.apg.workers.dev/mcp"
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "hyades": {
            "type": "http",
            "url": "https://hyades-mcp.apg.workers.dev/mcp"
        }
    }
}
```

### Gemini CLI

**Platform CLI: remote server**
```bash
gemini mcp add -t http hyades https://hyades-mcp.apg.workers.dev/mcp
```

## When to use it
- render LaTeX equations inside terminal sessions
- paste legible mathematical notation into source code comments
- generate ASCII fallbacks for environments without Unicode support
- format math for plain text emails without external images

## Example prompts
- Render `\sum_{k=0}^{n} \frac{x^k}{k!}` as Unicode text art with Hyades
- Convert this LaTeX matrix into plain ASCII for a code comment
