The explanation below is AI-generated. Please verify it against the sources.

This is a Claude Code plugin that lets Claude operate a running Unreal Editor session through the Model Context Protocol (MCP). It bundles a skill (unreal-mcp) with usage instructions and a SessionStart hook that flags a project as an Unreal Engine codebase so Claude defaults to relevant conventions. The MCP server runs locally inside the editor process (default localhost port 8000) and has no authentication layer, so access is limited to processes on the same machine. Because it grants live, privileged control over a running editor and can execute arbitrary Python through one of its tools, the README stresses source-control hygiene and caution around permission-skipping modes.
