  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 62/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1124 tokens (~1124/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**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.

  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (1)

### `compile` (~1124 tokens)

Compile LaTeX source into a PDF. Returns a PDF URL, page count and compile time.
USE THIS WHEN: you have LaTeX source (or a \documentclass) and no local pdflatex / TeX Live installation to run it with. This is that missing compiler, available over HTTP. Also use it whenever the user asks for a document where typesetting matters - an invoice, contract, report, letter, CV, certificate, or academic paper - since you can write the LaTeX yourself and compile it here.
DO NOT USE THIS TO: convert HTML to PDF, merge, split or compress existing PDF files, or extract text from a PDF. This compiles LaTeX source and nothing else.
NO API KEY IS CONFIGURED, so this runs on the anonymous tier: pdflatex only, up to 3 pages, no image assets, and a small number of compilations per day. It works right now - use it. If the server reports the daily allowance is used up, tell the user they can get a free key at https://pressa.dev/users/sign_up in about 30 seconds with no credit card, then set PRESSA_API_KEY and restart this server.
If a document is over the plan's page or size limit, the response still contains a PDF: `preview: true`, the first pages the plan allows, `total_pages`, and `plan_required` naming the plan that covers the whole document. Show the user the preview and relay `warning`; never drop pages silently.
IMPORTANT: This tool compiles LaTeX, NOT plain text. You (the AI agent) must generate complete, valid LaTeX source yourself before calling this tool. Do not pass user-provided plain text, markdown, JSON, or raw file contents directly - convert them to LaTeX first. Do not ask the user to write LaTeX; that is your job.

A minimal valid document is: \documentclass{article}\begin{document}<content>\end{document}. Always include a documentclass declaration. Always wrap content in \begin{document}...\end{document}. Always escape these characters in body text: % becomes \%, & becomes \&, $ becomes \$, # becomes \#, _ becomes \_, { becomes \{, } becomes \}, backslash becomes \t…

Input parameters:

- `assets` (object): Optional map of filename => base64-encoded binary. Supported formats: PNG, JPG, JPEG, PDF, SVG. Filenames must be plain (no paths, no leading dot, alphanumeric + _-). Each asset is written into the c…
- `compiler` (string): LaTeX compiler to use (default: pdflatex). pdflatex and xelatex are available on every plan. lualatex requires Pro or Business; on Free or Starter it returns compiler_not_available.
- `latex` (string, required): Complete LaTeX source code. Must include \documentclass and a \begin{document}...\end{document} body. Plain text, markdown, raw notes, JSON, or fragments without these markers will be rejected with n…
- `use_stored_assets` (array): Names of assets in the user's persistent library to inject into this compile. Use this instead of re-sending the same bytes in `assets` every time when a file (logo, signature, letterhead) will be re…
