Quick Start

1. Get an API key

Sign up at developer.topazlabs.com.

2. Add to your MCP client

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "Topaz Labs": {
      "command": "npx",
      "args": ["-y", "@topazlabs/mcp"],
      "env": {
        "TOPAZ_API_KEY": "<your-api-key>"
      }
    }
  }
}

3. Enhance images

You: "Enhance ~/Desktop/photo.jpg with Wonder 2"

Claude: I'll enhance your photo using Topaz Labs' Wonder 2 model.

[calls image-enhance tool]

Note: This tool requires a file path or URL — it cannot process images uploaded directly in the chat. It works best with Claude Cowork, which has file system access. It does not work in Claude Chat mode (no file system access).

Here's your enhanced image -- upscaled and sharpened with improved detail and clarity.

Compatibility

This server uses stdio transport, supported by all major MCP desktop clients:

Client	Status
Claude Cowork	✅ (recommended — has file system access)
Claude Desktop (Chat)	⚠️ Requires user to provide file paths manually
Cursor	✅
Windsurf	✅
VS Code (Copilot)	✅
Cline	✅
Claude Code	✅
Zed	✅

HTTP streaming transport (for ChatGPT, remote agents, web/mobile clients) is not yet supported but may be added in a future release.

Tool

image-enhance

Send an image, get back an enhanced version. Defaults to Standard V2 and auto-upscales to 2K.

size: { scale: 2 }              # Optional: exact dims, single dim, or scale factor
model: "Standard V2"            # Optional: defaults to Standard V2

Size options: { width, height } for exact, { width } or { height } for proportional, { scale } for a multiplier. If omitted, images under 2K are auto-upscaled to 2K width.
