## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS not yet verified: we couldn't determine whether a plaintext access path exists.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 50/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 5451 tokens (~5451/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

Render Hyades source

Render Hyades source to Unicode/ASCII text art. Hyades uses LaTeX-like syntax but outputs multi-line plain text instead of PDF. It supports math (fractions, integrals, matrices, Greek letters), tables with box-drawing frames, lists, flex-like layout (hbox/vbox), user-defined macros, and computation.

IMPORTANT: Always display the rendered output to the user directly in your response. The output is pre-formatted multi-line text art that depends on exact character alignment. You MUST use a fenced code block (triple backticks) or equivalent monospace/preformatted element to preserve spacing. Never display the output as regular prose text — column alignment, box-drawing characters, and fraction bars will break without a monospace font.

Input is a complete Hyades document. Plain text outside math delimiters is rendered as prose paragraphs. Use `$...$` for inline math and `$$...$$` for display math (centered on its own line).

\---

\## Math

Supports ~95% of LaTeX math syntax.

\### Inline vs Display

\```
Inline math: $a^2 + b^2 = c^2$ flows with text.

Display math gets its own block:

$$ a^2 + b^2 = c^2 $$
\```

Use `$...$` for inline, `$$...$$` for display. Display math is centered.

\### Variables and Operators

\```
$$ a + b - c $$
$$ a \times b \div c $$
$$ a \cdot b $$
$$ \pm x \quad \mp y $$
\```

\### Superscripts and Subscripts

\```
$$ x^2 \quad x_i \quad x_i^2 \quad x^{n+1} \quad x_{i,j} \quad a^{b^c} $$
\```

Use braces for multi-character exponents/subscripts: `x^{n+1}`, `x_{i,j}`.

\**Bracing rules:** Use braces for multi-token expressions: `x^{n+1}`, `x_{i,j}`. Commands that take arguments (like `\mathbf{v}`) work without extra braces: `x_\mathbf{v}` is equivalent to `x_{\mathbf{v}}`, matching TeX behavior.

\### Fractions

\```
$$ \frac{a}{b} $$
$$ \frac{x^2 + 1}{\sqrt{x^2 - 1}} $$
$$ \frac{\partial f}{\partial x} $$
\```

Fractions nest to infinite depth. `\dfrac` and `\tfrac` are accepted as aliases for `\frac`.

\### Roots

\```
$$ \sqrt{x} $$
$$ \sqrt[3]{x} $$
$$…

Input parameters:

- `ascii` (boolean): Use ASCII-only output instead of Unicode (default: false)
- `source` (string, required): Complete Hyades document source. Use $$...$$ for display math, $...$ for inline math. Plain text outside math is rendered as prose.
- `width` (integer): Output width in characters (default: 80). Use 80 for standard terminal width. Avoid going below 60 for complex math.
