Show HN: Relay – Connect Claude Desktop and Claude Code via MCP (github.com)

A new tool called Relay has been introduced to enhance communication between Claude Desktop and Claude Code, allowing seamless transfer of files, code, and conversation context between the two platforms. Utilizing a shared buffer connected via MCP (multi-channel protocol), users can simply invoke commands like "ask Desktop" or "send this to Code," enabling a smoother workflow without the need for cumbersome copy-pasting. This integration is significant as it leverages the unique strengths of both applications—Claude Desktop excels in dialogue and brainstorming, while Claude Code focuses on executing and refining code. Technical implications of Relay include automatic handling of context switching, which improves productivity by allowing users to maintain focus on their tasks. The setup requires adding specific configurations to the platforms, including installation of required packages and settings to facilitate the relay connection. Notifications are also embedded, alerting users when messages are waiting, ultimately creating a cohesive environment that negates project isolation but provides continuous access to all past interactions across tasks. The Relay tool aims to streamline the development process, enhancing collaboration and iterative improvements in AI/ML projects.
