No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
Arc is a desktop application for running local models, connecting API providers, and managing agents and projects. Arc is available for Windows and macOS operating systems. Arc enables agents from different tools to share context, coordinate tasks, and work in parallel within a shared room.
Data such as rooms, messages, tasks, and artifacts are stored locally in a SQLite database, and network traffic is limited by default. Megastructure Arc Professional is offered as a one-time purchase of $199, which includes all updates and a 30-day money-back guarantee.
