Common questions

Is CanvasKeep safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CANVASKEEP_API_KEY, CANVASKEEP_MASTER_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 25 days ago, and the latest version (0.6.2) reached the registry 25 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

CanvasKeep MCP Server

An MCP (Model Context Protocol) server that lets AI tools like Claude Code and Codex generate Excalidraw diagrams and save them directly into your CanvasKeep workspace.

Setup

1. Get an API key

Log in to CanvasKeep
Click your profile menu (top right) and select API Keys
Generate a new key and copy it immediately (you won't see it again)

2. Install and register

Claude Code:

claude mcp add canvaskeep \

-e CANVASKEEP_API_KEY=ck_your_key_here \ -- npx canvaskeep-mcp

Codex / other MCP clients:

"mcpServers": { "canvaskeep": { "command": "npx", "args": ["canvaskeep-mcp"], "env": { "CANVASKEEP_API_KEY": "ck_your_key_here" } } } }

3. Environment variables

Variable	Required	Default	Description
`CANVASKEEP_API_KEY`	Yes	-	Your API key from the CanvasKeep dashboard
`CANVASKEEP_MASTER_KEY`	No	-	Needed to read or edit encrypted diagrams. Copy it from canvaskeep.com/dashboard/encryption (Key for the MCP server)
`CANVASKEEP_API_URL`	No	`https://canvaskeep.com`	API base URL (override for local dev)

Available tools

Tool	Description
`list_workspaces`	List all your workspaces
`create_workspace`	Create a new workspace
`list_folders`	List folders in a workspace
`create_folder`	Create a new folder, optionally nested
`list_diagrams`	List diagrams in a workspace
`create_diagram`	Create a diagram, optionally inside a folder
`update_diagram`	Rename a diagram
`delete_diagram`	Permanently delete a diagram
`get_diagram_summary`	Get diagram metadata and element count
`get_diagram_scene`	Read the full Excalidraw scene of a diagram
`save_diagram_scene`	Write a full Excalidraw scene back to a diagram
`generate_diagram`	Generate a diagram from nodes and edges with auto-layout

Encryption

Diagrams you encrypt in CanvasKeep stay encrypted when an AI tool works with them. When get_diagram_scene or save_diagram_scene touches an encrypted diagram, this server decrypts and re-encrypts it locally (AES-GCM, see src/encryption.ts) using CANVASKEEP_MASTER_KEY. The master key never leaves your machine.

generate_diagram sends the nodes and edges you give it to CanvasKeep, which lays them out on the server, so diagrams generated this way are stored unencrypted.

Example usage

Ask Claude Code something like:

"Draw an architecture diagram of a web app with a React frontend, Node API, PostgreSQL database, and Redis cache"

Claude will use the MCP tools to create a diagram in your CanvasKeep workspace with properly laid-out boxes and labeled arrows.

Development

git clone https://github.com/CanvasKeep/canvaskeep-mcp.git

cd canvaskeep-mcp npm install npm run build CANVASKEEP_API_KEY=ck_... CANVASKEEP_API_URL=http://localhost:3000 node dist/index.js

To run your local build from Claude Code:

claude mcp add canvaskeep \

-e CANVASKEEP_API_KEY=ck_your_key_here \ -- node /path/to/canvaskeep-mcp/dist/index.js
