**One daemon. Many assistants. Shared project state.**

n2n-nexus is an open-source Model Context Protocol (MCP) coordination server for developers and teams who use multiple AI coding assistants across IDEs, machines, and projects. Use it when Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, JetBrains, or other MCP-enabled clients need a shared local coordination layer instead of isolated per-chat context.
