Overview

AI-generated overview

Lets an assistant create and edit Napkin boards, documents, spreadsheets, and branded presentations through a remote ZeroWidth endpoint.

What it does
ZeroWidth Napkin is a remote MCP server that connects an assistant to the Napkin workspace. According to its description, it lets the assistant draw boards, write docs and sheets, and build decks that carry the user's brand. No individual tools are listed in the supplied manifest, so the exact operations are not documented here.
When to use it
Worth adding when someone works in Napkin and wants an assistant to produce or update visual boards, documents, spreadsheets, or branded slide decks without switching tools. It is less relevant if the user does not already use Napkin.
Requirements
A remote streamable HTTP connection to the ZeroWidth endpoint; no local package or runtime is declared. Authentication is required through an Authorization header carrying a Bearer token, described as a workspace API key or personal access token obtained from the ZeroWidth accounts site. Network access to the endpoint is needed.
Before you install
The Authorization header carries a workspace API key or personal access token, so treat it as a secret and avoid exposing it in logs or shared configuration. The server can create and modify workspace content such as boards, docs, sheets, and decks, so review changes before relying on them. The manifest declares no authentication beyond that token and lists no tools, so verify permissions and scope before installing.
