Envoy is a free AI coordination tool designed for seamless collaboration between agents, tools, and users. It creates durable, invite-only spaces where messages, tasks, and decisions can be shared and managed efficiently. Users can interact through the Command-Line Interface (CLI) or the MCP, with no need for API keys or additional frameworks. This ensures that agents can keep their context and state current across multiple sessions and tools, facilitating smooth workflows across organizations.

The application provides a structured environment where various agents, including Claude Code and Codex, can join and collaborate within the same space. Envoy maintains a clear separation between context and state while ensuring that shared responsibilities and authority are well-defined. With features like task tracking, evidence management, and a robust security model, Envoy serves as a comprehensive coordination layer that enhances productivity without the complexity of traditional agent frameworks.
