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. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • No production dependencies, so there is no dependency health to assess. View diagnostics → Pass

Schema Quality & AI Usability69
  • AI-judged instruction clarity (excellent).Pass
  • 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. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management80
  • Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100

  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass

MCP tools · 5 exposed · ~1,123 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
supernote_list_files ~224

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.

NameTypeReqDescription
ipstring–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.
pathstring–Folder to list, as a `path`/`uri` from a previous listing. Defaults to the root.

No output schema declared.

No examples provided.

supernote_read_note ~232

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.

NameTypeReqDescription
ipstring–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.
pathstringyesThe note's `path` from supernote_list_files, e.g. /Note/obsidian/meeting.note.

No output schema declared.

No examples provided.

supernote_render_note ~234

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.

NameTypeReqDescription
ipstring–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.
pagesarray–1-indexed page numbers to render. Defaults to all pages (capped at 20).
pathstringyesThe note's `path` from supernote_list_files, e.g. /Note/obsidian/sketch.note.

No output schema declared.

No examples provided.

supernote_snapshot ~185

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.

NameTypeReqDescription
ipstring–Device IP (optionally with :port) shown on the Supernote mirroring popup. Defaults to the SUPERNOTE_IP environment variable.

No output schema declared.

No examples provided.

supernote_upload_file ~248

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.

NameTypeReqDescription
directorystring–Target folder on the device (a `path` from supernote_list_files). Defaults to the root.
filenamestring–Name to save the file as on the device. Defaults to the local file's name.
ipstring–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.
pathstringyesLocal filesystem path of the file to upload.

No output schema declared.

No examples provided.

Common questions

What is the Supernote MCP server?

Supernote is an MCP server listed in the public MCP registry as io.github.ridget/supernote-mcp. Capture the screen, read/render notes, and upload files on a Ratta Supernote from an AI agent. This page covers its npm package (supernote-mcp).

Is the Supernote MCP server safe to use?

Supernote scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 24 September 2026. 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 Supernote MCP server expose?

Supernote exposes 5 tools: supernote_snapshot, supernote_list_files, supernote_read_note, supernote_render_note, supernote_upload_file. Their descriptions and schemas cost roughly 1,123 tokens of context every time the server is loaded.

Is the Supernote MCP server still maintained?

Supernote is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the Supernote MCP server under?

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