## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-11-05.

- **Supply Chain Security**: 23/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs were checked across the 92 of 92 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 30 of 92 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 26 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 514 tokens (~257/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 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 MarsDawn MCP server?

MarsDawn ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 8925b836c7ab3959f4e7a98452aa0fe60442c38c79055304219998aebbcb5f41; the commands to do that are on this page. If it does not match, do not open it.

## MCP tools (2)

### `export_markdown_to_pdf` (~286 tokens)

Export Markdown to PDF

Export a Markdown file to a paginated PDF on this Mac with the marsdawn command-line tool, rendered like MarsDawn's preview, Mermaid diagrams included. Needs marsdawn 0.5.0 or later (`brew install redtear1115/tap/marsdawn`). Writes the PDF beside the input unless `output` is given, and won't replace an existing PDF unless `force` is true. Web images are left out unless `allowRemoteImages` is true. It reads and writes only inside the folders the user allowed, and refuses anything outside them.

Input parameters:

- `allowRemoteImages` (boolean): Load images from the web while rendering. This reaches the network.
- `force` (boolean): Replace the output file if it already exists.
- `input` (string, required): Absolute path of the Markdown file to export, inside an allowed folder; a plain absolute path without `.` or `..` components.
- `output` (string): Absolute path to write the PDF to, inside an allowed folder; a plain absolute path without `.` or `..` components, and it must end in .pdf. Defaults to the input path with a .pdf extension.
- `paper` (string): Paper size. Defaults to a4.
- `theme` (string): Preview theme (light palette). Defaults to $MARSDAWN_THEME, or dawn.

Output parameters:

- `diagramErrorDetails` (array): The same failures as `diagramErrors`, in the same order, each as   `{message, fenceLine, line}`. `fenceLine` is the document line the diagram's fence starts on,   present whenever that's known. `line…
- `diagramErrors` (array): One message per Mermaid diagram that failed to render. The PDF is still written.
- `ok`
- `output` (string): Absolute path of the PDF that was written.
- `pages` (integer): Number of pages in the PDF.
- `paper`: Paper size used for the export.
- `theme`: Theme used for the export.

### `open_in_marsdawn` (~228 tokens)

Open in MarsDawn

Open a Markdown file in the MarsDawn app on this Mac for the user to review, with the marsdawn command-line tool. Needs the MarsDawn app, from the Mac App Store (https://apps.apple.com/app/id6812925073). Call this once per file: the window stays open and follows the file's later edits by itself, so there's no need to call it again after every change, only when a new file needs review or the user should be sent to a different line. `background` opens the file without bringing MarsDawn to the front, so the window the user is already working in keeps focus. It opens only files inside the folders the user allowed, and refuses anything outside them.

Input parameters:

- `background` (boolean): Open without bringing MarsDawn to the front.
- `line` (integer): Line to land on.
- `path` (string, required): Absolute path of the Markdown file to open, inside an allowed folder; a plain absolute path without `.` or `..` components. Must be a file, not a folder.

Output parameters:

- `app` (string): Path of the MarsDawn app that opened them.
- `ok`
- `opened` (array): The files that were opened, in the order given.
