Mergy is a Chrome extension designed to streamline the process of integrating GitHub repository contents with Anthropic's Claude AI. This tool allows users to fetch files from any public GitHub repository and combine selected files into a single text document, optimizing the content for AI processing. The extension is particularly beneficial for developers working on small to medium-sized libraries, enabling them to provide comprehensive context to Claude for AI-assisted programming tasks.

Key features of Mergy include customizable file inclusion/exclusion rules, adherence to .gitignore rules, and support for custom ignore patterns. The user-friendly interface provides file size estimates, making it easier for users to manage their selections. To utilize Mergy, users simply need to visit a GitHub repository, configure their settings, select the desired files, download the combined file, and upload it to Claude Projects for analysis or code generation. A GitHub Personal Access Token is required for API access, ensuring secure authentication.
