Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00189 | $0.01495 |
| Opus 5 | $0.00095 | $0.00747 |
| Sonnet 5 | $0.00038 | $0.00299 |
| Haiku 4.5 | $0.00019 | $0.00150 |
Grade A, and why
upmath scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UpMath — LaTeX/TikZ/markdown-math rendering (no local TeX)
Guidance for the upmath-mcp server. It renders LaTeX server-side through
i.upmath.me (TeX Live behind an SVG/PNG API), so nothing
needs a local TeX installation. Tools appear as
mcp__plugin_upmath-mcp_upmath-mcp__<tool>.
When to use
- Turn an equation or a TikZ/pgfplots/circuitikz/tikz-3dplot diagram into an SVG or PNG.
- Convert a markdown/LaTeX paper with
$$...$$math into publication-ready HTML — the UpMath round-trip. - Validate or inventory the LaTeX in a document, build an equation sheet or notation table, or diff/grid equations while iterating.
Tools (16)
Single render / embed
| Tool | Use it for |
|---|---|
render_equation |
One LaTeX equation → SVG/PNG (optionally saveTo). |
render_tikz |
A TikZ / pgfplots / circuitikz / tikz-3dplot diagram → SVG/PNG. Pass the packages array. |
get_render_url |
The i.upmath.me/svg/<encoded> URL to embed directly, no file written. |
check_syntax |
Validate one LaTeX snippet by attempting to render it. Cheap pre-flight. |
Documents / papers
| Tool | Use it for |
|---|---|
render_paper |
A full markdown paper with $$...$$ → publication-ready HTML (headings, bold/italic, lists, tables, code). Default useUpmath:false = KaTeX (fast, client-side); useUpmath:true = all math via UpMath SVG (slower, supports TikZ). See the gotcha below. |
render_markdown_with_math |
Markdown with $$...$$ → HTML with embedded UpMath SVG math. |
scan_document_math |
Inventory every equation in a markdown file (audit before rendering). |
validate_equations |
Validate all equations in a file, reporting failures. |
Batch / iteration
| Tool | Use it for |
|---|---|
render_batch |
Many equations → one file each. |
render_batch_cached |
Same, but skips unchanged equations — much faster on re-runs. |
render_equation_sheet |
A set of named equations → one reference-sheet HTML page. |
render_parameter_grid |
Render a LaTeX template across a grid of parameter values. |
render_diff |
Two versions of an equation side by side (HTML comparison). |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

upmath is a skill published in the GitHub repository danielsimonjr/upmath-mcp (2 stars, last pushed today), licensed MIT. It adds 189 tokens to every session and 1,495 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
