Setup snapshot

git clone https://github.com/psmoore/etcha-mcp-app.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Full README

Etcha

An Etch a Sketch style knowledge graph visualizer for Claude. Draw interactive node-and-edge diagrams with that classic retro toy aesthetic - complete with spinning knobs!

Works with Claude.ai, Claude Desktop, VS Code (Insiders), and other MCP-compatible clients.

Etcha Screenshot

Features

  • Etch a Sketch Design - Red frame, green-gray screen, white spinning knobs
  • Orthogonal Lines - All connections are horizontal and vertical only, just like the real toy
  • Spinning Knobs - Left knob spins for horizontal movement, right for vertical
  • Interactive Editing - Double-click to add nodes, Shift+drag to connect them
  • Zoom & Pan - Mouse wheel to zoom, drag empty space to pan
  • Save/Load - Persist your graphs locally

Installation

Option 1: npm (Recommended)

npx etcha-mcp --stdio

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "etcha": {
      "command": "npx",
      "args": ["etcha-mcp", "--stdio"]
    }
  }
}

Option 2: From Source

git clone https://github.com/yourusername/etcha.git
cd etcha
npm install
npm run build

Then add to your Claude Desktop config:

{
  "mcpServers": {
    "etcha": {
      "command": "npx",
      "args": ["tsx", "/path/to/etcha/main.ts", "--stdio"]
    }
  }
}

Usage

In Claude Desktop, ask Claude to draw a graph using Etcha:

  • "Use Etcha to draw a graph of database types"
  • "Draw a mind map of project architecture in Etcha"
  • "Visualize this concept in Etcha"

Interactive Controls

| Action | How | |--------|-----| | Add node | Double-click on empty space | | Move node | Click and drag | | Connect nodes | Shift + drag from one node to another | | Delete node/edge | Right-click | | Pan canvas | Click and drag on empty space | | Zoom | Mouse wheel or +/- buttons | | Save graph | Click "Save" button | | Load graph | Click "Load" button |

How It Works

Etcha is an MCP App - it combines an MCP tool with an interactive HTML UI. When Claude calls the etcha tool with a graph definition, the UI renders it with animated "drawing" effects and spinning knobs.

The tool accepts:

{
  nodes: [
    { id: "1", label: "Node A", x?: 100, y?: 100 },
    { id: "2", label: "Node B" }
  ],
  edges: [
    { from: "1", to: "2", label?: "connects to" }
  ]
}

Cloud Deployment (for claude.ai)

To use Etcha with claude.ai or other web-based MCP clients, deploy the server to the cloud.

Option 1: Docker

# Build the image
docker build -t etcha-mcp .

# Run the container
docker run -p 3001:3001 etcha-mcp

The server will be available at http://localhost:3001/mcp.

Option 2: Deploy to a Cloud Platform

Deploy to any platform that supports Node.js or Docker:

Railway / Render / Fly.io:

  1. Connect your GitHub repository
  2. Set the start command to npm run start (or use the Dockerfile)
  3. The server runs on port 3001 by default (configurable via PORT env var)

Environment Variables:

  • PORT - Server port (default: 3001)

Connecting claude.ai to your server

Once deployed, connect claude.ai to your server's /mcp endpoint (e.g., https://your-app.railway.app/mcp).

See the MCP documentation for details on connecting remote MCP servers.
