### `latex_look` (~516 tokens)

See what a LaTeX page actually looks like

Compile a LaTeX document, render a page to a PNG you can see, and map a point or a text anchor back to the exact source line. Use this whenever someone describes a page visually — a table style, a rule to remove, spacing, a line running into the margin, a figure that is too large — and before saying a layout change is done. Note that `page` is the PDF page index, not the number printed on the page.

Input parameters:

- `audit` (boolean): Audit every page for layout regressions against the previous audit of this document: pages that stop short, pages that start low, nearly empty pages — but only the ones this edit introduced. Run it a…
- `auditBlankMm` (number): How deep a hole at the foot of a page must be (mm) before the audit calls it one. Defaults to 30.
- `compare` (string): Path to an earlier PDF of the same document. The page is diffed against it and a before image is rendered.
- `dpi` (number): Render resolution, 50-300. Defaults to 120.
- `engine` (string): auto | xelatex | lualatex | pdflatex | latexmk | tectonic. Defaults to auto, which picks from what the document uses.
- `file` (string, required): Path to the main .tex file (absolute, or relative to the current directory).
- `fresh` (boolean): Ignore the build cache and compile from scratch. Use only if you suspect the cache is stale.
- `page` (number): PDF page to render, 1-based. Omit when using `text`, which finds the page itself.
- `pointX` (number): X of a point on the page, together with pointY. Feed back the bbox of a previous diff to inspect what changed.
- `pointY` (number): Y of the same point, in PDF points from the top-left corner of the page.
- `sequence` (string): Check reading order for numbered labels with this prefix (e.g. '图' or 'Figure'). An inversion is what a figure that became a float while its neighbours stayed inline causes: the reader turns the page…
- `text` (string): A short string visible on the page (a caption, a heading, a unique phrase). Resolves to its source file:line and page.

### Is the LaTeX Look MCP server safe to use?

LaTeX Look scores 69 out of 100 on VerifyMCP. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the LaTeX Look MCP server expose?

LaTeX Look exposes 1 tool: latex_look. Their descriptions and schemas cost roughly 516 tokens of context every time the server is loaded.

### Is the LaTeX Look MCP server still maintained?

### What licence is the LaTeX Look MCP server under?

LaTeX Look declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
