Claude Assistant

Claude Assistant integrates Anthropic's Claude AI directly into the Unreal Engine editor, giving you an AI pair programmer that understands your project — your Blueprints, your DataTables, your assets.

Version: 0.1.0 · Engine: UE 5.3+ · Platform: Win64, Linux

Chat panel docked in the UE editor

What it does​

Instead of switching back and forth between your editor and a browser, Claude Assistant lets you ask questions and issue commands directly from within Unreal Engine. Claude can read your open assets, inspect Blueprint graphs, analyze DataTable schemas, and even make changes — all without leaving the editor.

Key Features​

Two operation modes​

ModeBest for
Claude Code (subprocess)Full power: tool calling, prompt caching, MCP protocol
Direct APISimple setup: just paste your API key, no CLI required

Context-aware conversations​

Claude automatically detects which asset you have focused — open a Blueprint, switch to a DataTable, Claude knows. No copy-pasting node names or struct fields.

Read your project​

  • List Blueprint member variables, functions, event graphs, macro graphs
  • Inspect individual graph nodes and their connections
  • Read DataTable schemas and row data (paginated)
  • Identify unused variables

Modify your project (with confirmation)​

  • Add, rename, or delete Blueprint variables
  • Clean up unused variables in one shot
  • Add/update/delete DataTable rows (single or batch)
  • Reposition Blueprint nodes and add comment boxes
  • Execute Python scripts for bulk operations

Persistent conversations​

Every conversation is saved under Saved/Config/UCA/conversations/. Pick up where you left off, switch between conversations from the sidebar, or run sessions in the background while you keep working.
