## 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 2026-09-25.

- **Endpoint Security**: 80/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 60/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 489 tokens (~489/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**: 10/100
  - Stability observed for 3 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.
- **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 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Pressa - LaTeX to PDF MCP server?

Pressa - LaTeX to PDF is a hosted endpoint at https://api.pressa.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-25 (score 72, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-24 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-23 (score 71, 0)

- [functional improvement] Stability: unverified → 0.03

### 2026-09-22 (score 71)

First indexed and scored.

Compile LaTeX to PDF

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 required. Anonymous callers get a small number of compilations per day and failed attempts do not count, so you can iterate on your LaTeX for free. Send an API key in the Authorization header to raise the limits.
With a key, a document over the plan's page or size limit still returns 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 must generate complete, valid LaTeX source yourself before calling it. Do not pass plain text, markdown or JSON directly - convert them to LaTeX first, and never ask the user to write LaTeX.

A minimal valid document is: \documentclass{article}\begin{document}<content>\end{document}. Escape these in body text: % & $ # _ { } and backslash.

If compilation fails the response includes a `diagnosis` naming the cause and a concrete suggested fix, often a missing \usepackage. Apply it and call again yourself rather than showing the user a TeX log.

Input parameters:

- `compiler` (string): Defaults to pdflatex. Anonymous callers may only use pdflatex.
- `latex` (string, required): Complete LaTeX source, including \documentclass and \begin{document}...\end{document}.
