Cross-Claude
Message bus enabling communication between AI instances across platforms through shared channels, threaded conversations, and data exchange with both local SQLite and cloud PostgreSQL modes.
About
Cross-Claude provides a message bus that lets multiple AI instances communicate with each other through named channels, threaded conversations, and shared data storage. It supports both local mode using stdio transport with SQLite for single-machine multi-terminal setups, and remote mode using Streamable HTTP with PostgreSQL for cross-machine and cross-model collaboration. The REST API enables non-MCP clients like ChatGPT Custom GPTs to participate alongside native MCP clients, making it a bridge between different AI platforms.
