A Model Context Protocol (MCP) server for displaying images from your local filesystem directly in Claude conversations.

• Multiple Formats: Supports JPG, PNG, GIF, BMP, WebP, and SVG files
• Path Resolution: Supports ~ for home directory and relative paths

Installation

1. Build the project:

npm install
npm run build

2. Add to your Claude MCP configuration (usually in ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "image-viewer": {
      "command": "node",
      "args": ["/Users/ian/image-viewer-mcp/dist/index.js"]
    }
  }
}

Available Tools

list-images

Find and list image files in a directory.

• searchPath (string): Directory path to search for images
• recursive (boolean, optional): Whether to search subdirectories recursively

image-info

Get detailed information about an image file without loading the full image data.

Usage Examples

- Tool: display-image
- imagePath: ~/Pictures/Headshot_Headphones.jpg

Troubleshooting

• Ensure the image file exists and is readable
• Check that the file extension is supported
• Verify the path is correct (use absolute paths for reliability)
• Large images may take longer to load due to base64 encoding
