## 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 2026-08-03.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 61 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1392 tokens (~278/item across 5 items; 5 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.
- **Capabilities**: 100/100
  - 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 (5)

### `supernote_snapshot` (~185 tokens)

Supernote snapshot

Capture the user's Supernote e-ink tablet's LIVE screen right now (its screen mirror) and return it as an image. Call this when the user refers to what's currently on the tablet — what they just sketched, drew, or handwrote during a whiteboarding/planning session ("what did I just draw?", "look at my screen", "see my sketch"). This is the current screen, NOT a saved file: to read or show a notebook saved earlier, use supernote_list_files then supernote_read_note (text) or supernote_render_note (images). Requires Screen Mirroring enabled on the device, with the device and this host on the same Wi-Fi and no VPN/proxy.

Input parameters:

- `ip` (string): Device IP (optionally with :port) shown on the Supernote mirroring popup. Defaults to the SUPERNOTE_IP environment variable.

### `supernote_list_files` (~224 tokens)

List Supernote files

List the notebooks, documents, and folders saved on the user's Supernote e-ink tablet, over its Browse & Access Wi-Fi file server. Call this to find a saved note before reading or rendering it — for example when the user says "read my notes from yesterday" or "what's on my Supernote?". Returns each entry's name, whether it is a folder, size, date, and a `path` to pass to supernote_read_note / supernote_render_note (or back into this tool to descend into a folder). Requires Browse & Access enabled on the device (swipe down → Browse & Access), same Wi-Fi, no VPN/proxy.

Input parameters:

- `ip` (string): Device IP (optionally with :port) shown on the Supernote's mirroring or Browse & Access popup. Defaults to the SUPERNOTE_IP environment variable; if unset, the device is found by a LAN scan.
- `path` (string): Folder to list, as a `path`/`uri` from a previous listing. Defaults to the root.

### `supernote_read_note` (~232 tokens)

Read a Supernote note as text

Read the recognized handwriting and typed text from a saved Supernote note (.note file) as plain text. Call this when the user wants the CONTENTS of a specific note — e.g. "read my notes from yesterday", "summarise my meeting notes", "what did I write in <note>". Use supernote_list_files first to get the note's `path`. Returns recognized text per page — cheap and accurate, so prefer it over images when the user wants the words. If the note has no recognized text (on-device handwriting recognition wasn't run), it says so; use supernote_render_note for page images instead. Requires Browse & Access enabled, same Wi-Fi, no VPN/proxy.

Input parameters:

- `ip` (string): Device IP (optionally with :port) shown on the Supernote's mirroring or Browse & Access popup. Defaults to the SUPERNOTE_IP environment variable; if unset, the device is found by a LAN scan.
- `path` (string, required): The note's `path` from supernote_list_files, e.g. /Note/obsidian/meeting.note.

### `supernote_render_note` (~234 tokens)

Render Supernote note pages as images

Render the pages of a saved Supernote note (.note file) as images. Call this when the user wants to SEE a note — sketches, diagrams, drawings — or when supernote_read_note reported the note has no recognized text. Use supernote_list_files first to get the note's `path`. By default renders all pages (capped); pass `pages` to select specific 1-indexed pages. Prefer supernote_read_note when the user only wants the words (text is far cheaper than images). Requires Browse & Access enabled, same Wi-Fi, no VPN/proxy.

Input parameters:

- `ip` (string): Device IP (optionally with :port) shown on the Supernote's mirroring or Browse & Access popup. Defaults to the SUPERNOTE_IP environment variable; if unset, the device is found by a LAN scan.
- `pages` (array): 1-indexed page numbers to render. Defaults to all pages (capped at 20).
- `path` (string, required): The note's `path` from supernote_list_files, e.g. /Note/obsidian/sketch.note.

### `supernote_upload_file` (~248 tokens)

Upload a file to the Supernote

Upload a local file to the user's Supernote e-ink tablet over its Browse & Access Wi-Fi server. Use this to put a document on the device for the user to read or annotate — e.g. a PDF or file the agent just created or downloaded. This WRITES to the device. Give the local file `path`; optionally a target `directory` on the device (a `path` from supernote_list_files, default root) and a `filename` to save as (default: the local file's name). Requires Browse & Access enabled, same Wi-Fi, no VPN/proxy.

Input parameters:

- `directory` (string): Target folder on the device (a `path` from supernote_list_files). Defaults to the root.
- `filename` (string): Name to save the file as on the device. Defaults to the local file's name.
- `ip` (string): Device IP (optionally with :port) shown on the Supernote's mirroring or Browse & Access popup. Defaults to the SUPERNOTE_IP environment variable; if unset, the device is found by a LAN scan.
- `path` (string, required): Local filesystem path of the file to upload.
