Supernote runs on your own machine — the client starts it, so there is no endpoint to ping. 79 installs a week from npm. Last commit 22 Sep 2026.
Capture the screen, read/render notes, and upload files on a Ratta Supernote from an AI agent.
Today is the operative word: we check Supernote every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Optional settings from the registry entry, left out of the block above:
SUPERNOTE_IP (Device IP (optionally with :port) from the Supernote mirroring popup. Optional — if unset, the server scans the LAN for the mirror), SUPERNOTE_DISCOVER (Set to 0 to disable the LAN-scan fallback used when SUPERNOTE_IP is unset or unreachable).
Upload local files up to 5 GB to Notion and attach them to pages, read from disk, not the chat.
Capture & annotate your screen from an AI agent: arrows, boxes, text, highlight, blur/redact.
Capture website screenshots from any MCP client via the ScreenshotRender API.
Your recent screen captures as structured JSON your AI agent can read. Local only, no network.
Tasks that outlive the chat. Capture features and tasks on your phone; your AI agent picks them up.
Read and write your Caliu notes from any MCP client: search, create, tag, remind, attach files.
Local OCR & screen understanding for agents: read any window, find what to click. No uploads.
Screenshot, PDF and Open Graph image API for AI agents: capture pages, render PDFs, make OG images.
