Setup snapshot

git clone https://github.com/mcp-tool-shop-org/websketch-mcp.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
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.

# 1. websketch_validate - preflight check (always call first)
# 2. websketch_render   - ASCII wireframe
# 3. websketch_diff     - compare two captures
# 4. websketch_fingerprint - structural hash

Features

🛡️ websketch_validate: Preflight validation (never throws, returns { ok: true/false })
🎨 websketch_render: Render WebSketch IR captures to ASCII wireframes
🔍 websketch_diff: Compute diffs between UI captures
🔑 websketch_fingerprint: Generate deterministic fingerprints for captures

Installation

npm

npm install -g websketch-mcp

From Source

git clone https://github.com/mcp-tool-shop-org/websketch-mcp.git
cd websketch-mcp
npm ci
npm run build
npm link

Usage

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "websketch": {
      "command": "websketch-mcp"
    }
  }
}

Programmatic

# Run as stdio server
websketch-mcp

Or programmatically in Node.js:

import { spawn } from 'child_process';

const server = spawn('websketch-mcp', [], {
  stdio: ['pipe', 'pipe', 'inherit'],
});

// Send MCP protocol messages via stdin/stdout

Tools

websketch_render

Render a WebSketch IR capture to ASCII wireframe.

Input:

{
  "capture": {
    "root": {
      "type": "Frame",
      "id": "root",
      "children": [...]
    }
  }
}

Output:

┌─────────────────────┐
│ Frame (root)        │
│ ├── Button (#btn1)  │
│ └── Text (#text1)   │
└─────────────────────┘

websketch_diff

Compute a diff between two WebSketch IR captures.

Input:

{
  "before": { "root": {...} },
  "after": { "root": {...} }
}

Output:

{
  "added": [...],
  "removed": [...],
  "modified": [...]
}

websketch_fingerprint

Generate a deterministic fingerprint for a capture.

Input:

{
  "capture": { "root": {...} }
}

Output:

abc123def456...

Publishing

The package is configured with pre-publish safety checks:

# This will automatically:
# 1. Run type checking
# 2. Run linting
# 3. Run tests
# 4. Build the package
npm publish

Manual publish steps:

# Bump version
npm version patch|minor|major

# Publish to npm
npm publish

# Push tags
git push --follow-tags

Troubleshooting

CLI Not Found After Install

# Ensure global bin directory is in PATH
npm config get prefix

# Or use npx
npx websketch-mcp

Build Failures

# Clean and rebuild
npm run clean
npm ci
npm run build

Permission Errors on Unix

The post-build script automatically makes dist/index.js executable. If you encounter issues:

chmod +x dist/index.js
