Details
From the project READMEEditItAll MCP Server
mcp-name: io.github.Subcue/edititall-mcp
EditItAll is a free, local-first suite of in-browser editors (photo, vector, PDF, spreadsheet, Word, slides, image convert/compress) built by Subcue AI LLC. This repository is the Model Context Protocol server that lets Claude Code, Claude Desktop, Cursor, and any MCP client operate those editors on your machine.
Your files never leave the device. The server launches a local headless Chrome, loads the editors from edititall.com (or a local wrangler dev URL), and drives their official automation hooks. The AI client only sees tool results (cell values, file sizes, screenshots you request).

Requirements
- Node.js 22+ (built-in
WebSocket) - Chrome, Edge, Chromium, or Brave installed locally
Install
From npm:
npx -y @edititall/mcp
# or
npm i -g @edititall/mcp
claude mcp add edititall -- edititall-mcp
From crates.io (Rust wrapper):
cargo install edititall-mcp
claude mcp add edititall -- edititall-mcp
The Rust binary embeds edititall-mcp.mjs and execs node. Set NODE if node is not on PATH.
Claude Desktop (one click). Download edititall-mcp.mcpb and drag it into Claude Desktop → Settings → Extensions. Claude Desktop ships its own Node runtime.
Claude Code (Node, no Rust):
curl -fsSL https://edititall.com/edititall-mcp.mjs -o ~/edititall-mcp.mjs
claude mcp add edititall -- node ~/edititall-mcp.mjs
Or clone this repo:
git clone https://github.com/Subcue/edititall-mcp.git
claude mcp add edititall -- node /path/to/edititall-mcp/edititall-mcp.mjs
Cursor / other stdio clients (mcp.json):
{
"mcpServers": {
"edititall": {
"command": "edititall-mcp"
}
}
}
Node-only equivalent: "command": "node", "args": ["/path/to/edititall-mcp.mjs"].

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
