Claireon is an Unreal Engine editor plugin that runs a [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server inside the editor, exposing hundreds of editor automation tools for AI-assisted development workflows behind a deliberately small MCP surface (`tool_search` + `python_execute`). It enables AI assistants like [Claude Code](https://docs.anthropic.com/en/docs/claude-code) to read, search, inspect, and edit Unreal assets directly.
## Features
- **Hybrid Tool Discovery** — `tool_search` ranks the full tool catalog with SQLite FTS5 + a vendored embedding model, so agents find the right tool without a giant tool list
- **Blueprint Editing** — Read and modify Blueprint graphs, properties, components, and connections
- **Animation Authoring** — Anim sequ Read full README on GitHub → Get the weekly AgentRank digest
