hmem vs mcp_agent_mail_rust

hmem: hmem is a memory system for AI agents that persists project context across sessions, devices, and AI providers. It uses a 5-level lazy loading architecture to minimize token usage while retaining full details. It supports auto-logging, background checkpoints, and cross-platform sync.; mcp_agent_mail_rust: Agent Mail is a mail-like coordination layer for AI coding agents, exposed as an MCP server with 37 tools and 25 resources. It features a Git-backed archive, SQLite indexing, an interactive 16-screen TUI, a server-rendered web UI, and an agent-first robot CLI. It prevents conflicts through advisory file reservations and enables asynchronous threaded messaging among agents.
