High-precision image recognition and description using the GPT-4o-mini model
Image URL validity checking
Image loading from local files and Base64 encoding

Installation

Installing via Smithery

To install Image Analysis Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @champierre/image-mcp-server --client claude

Manual Installation

# Clone the repository
git clone https://github.com/champierre/image-mcp-server.git # or your forked repository
cd image-mcp-server

# Install dependencies
npm install

# Compile TypeScript
npm run build

Configuration

To use this server, you need an OpenAI API key. Set the following environment variable:

OPENAI_API_KEY=your_openai_api_key

MCP Server Configuration

To use with tools like Cline, add the following settings to your MCP server configuration file:

For Cline

Add the following to cline_mcp_settings.json:

{
  "mcpServers": {
    "image-analysis": {
      "command": "node",
      "args": ["/path/to/image-mcp-server/dist/index.js"],
      "env": {
        "OPENAI_API_KEY": "your_openai_api_key"
      }
    }
  }
}

For Claude Desktop App

Add the following to claude_desktop_config.json:

{
  "mcpServers": {
    "image-analysis": {
      "command": "node",
      "args": ["/path/to/image-mcp-server/dist/index.js"],
      "env": {
        "OPENAI_API_KEY": "your_openai_api_key"
      }
    }
  }
}

Usage

Once the MCP server is configured, the following tools become available:

analyze_image: Receives an image URL and analyzes its content.
analyze_image_from_path: Receives a local file path and analyzes its content.

Usage Examples

Analyzing from URL:

Please analyze this image URL: https://example.com/image.jpg

Analyzing from local file path:

Please analyze this image: /path/to/your/image.jpg

Note: Specifying Local File Paths

When using the analyze_image_from_path tool, the AI assistant (client) must specify a valid file path in the environment where this server is running.

If the server is running on WSL:
- If the AI assistant has a Windows path (e.g., C:\...), it needs to convert it to a WSL path (e.g., /mnt/c/...) before passing it to the tool.
- If the AI assistant has a WSL path, it can pass it as is.
If the server is running on Windows:
- If the AI assistant has a WSL path (e.g., /home/user/...), it needs to convert it to a UNC path (e.g., \\wsl$\Distro\...) before passing it to the tool.
- If the AI assistant has a Windows path, it can pass it as is.

Path conversion is the responsibility of the AI assistant (or its execution environment). The server will try to interpret the received path as is.

Note: Type Errors During Build

When running npm run build, you may see an error (TS7016) about missing TypeScript type definitions for the mime-types module.

src/index.ts:16:23 - error TS7016: Could not find a declaration file for module 'mime-types'. ...

This is a type checking error, and since the JavaScript compilation itself succeeds, it does not affect the server's execution. If you want to resolve this error, install the type definition file as a development dependency.

npm install --save-dev @types/mime-types
# or
yarn add --dev @types/mime-types

Development

# Run in development mode
npm run dev
