# 🕵️‍♀️ test-mcp: ExifTool + Steganography MCP Server This project is an MCP (Model Context Protocol) based server that uses ExifTool to perform metadata extraction and simple LSB (Least Significant Bit) steganography on image files. ## 🚀 Features - 📷 Extract metadata from files using ExifTool - 🔎 Extract raw binary data from image files - 🧬 Embed and extract hidden data using LSB steganography (BMP files) - 🛠️ List all tags supported by ExifTool ## 📦 Installation ```bash git clone https://github.com/your-username/test-mcp.git cd test-mcp npm install npm run build ``` ## 🧪 Run To start using MCP Inspector: ```bash npx @modelcontextprotocol/inspector node build/index.js /usr/local/bin/exiftool ``` > Replace `/usr/local/bin/exiftool` with the path to ExifTool on your system. ## 🛠️ Available Tools ### 1. `extract-metadata` Extracts all metadata from a file in JSON format. ### 2. `extract-binary-data` Extracts binary data from an image file in hex, binary, or base64 format. ### 3. `embed-steganography-data` Embeds text data into a BMP image using LSB steganography. ### 4. `extract-steganography-data` Extracts hidden text from a BMP image that was embedded using LSB. ### 5. `list-exiftool-tags` Lists all metadata tags supported by ExifTool. ## 🔧 Development This project is written in TypeScript. To build: ```bash npm run build ``` ## 📂 Project Structure ``` . ├── index.ts # Main server file (TypeScript) ├── index.js # Compiled JavaScript ├── package.json ├── tsconfig.json ``` ## 📜 License MIT License --- ### ✨ Contributing Pull requests and feedback are welcome!
