Claireon is an Unreal Engine 5 plugin that implements a Model Context Protocol server, exposing hundreds of editor automation tools via a minimal two-tool MCP surface for AI-assisted game development. Its hybrid tool discovery using SQLite FTS5 and a vendored embedding model, coupled with sophisticated multi-worktree proxy support and deterministic port assignment, makes it a highly innovative bridge between AI agents and Unreal Editor workflows.

Target audience: game developers
