Everything you need to start analyzing Blueprints, chatting with AI, and understanding your project faster.
NodeLens plugin folder manually into your project's Plugins/ directory. Re-open your project — you'll be prompted to compile the plugin. Click Yes.
Plugin pending Fab approval. The NodeLens UE5 plugin is currently under review on the Fab marketplace. Check back soon or follow us on X @nodelens_io for updates.
http://localhost:7823).
NodeLens saves Blueprint data as plain .md files on your machine. Before you send anything, tell NodeLens where to store them.
Documents\NodeLens Projects. You can change this at any time.
Each UE5 project you send becomes its own subfolder inside this directory. All files are plain Markdown — you can open them in any text editor or Obsidian.
NodeLens plugs directly into UE5 — no copy-paste required.
The project name is set in the UE5 plugin settings (Edit → Project Settings → Plugins → NodeLens). Make sure it matches an existing project in NodeLens, or NodeLens will create a new one automatically.
Once a Blueprint is loaded, you can switch between several views using the tab bar at the top of the viewer:
The built-in AI chat lets you ask questions about your Blueprints in plain English. NodeLens sends your Blueprint context directly to your chosen AI provider — no middleman.
Your data stays yours. API calls go directly from your machine to your chosen provider. NodeLens never sees your Blueprint content or your API key.
If you use Claude Desktop, you can connect NodeLens as an MCP server. This lets Claude read all your saved Blueprints directly — no copy-paste, no context window limits.
%APPDATA%\Claude\claude_desktop_config.json. Open it in any text editor (e.g. Notepad). If the file doesn't exist, create it.
mcpServers object — replace the path with the actual location of your NodeLens MCP server file:
{
"mcpServers": {
"nodelens": {
"command": "node",
"args": ["C:\\Users\\YourName\\AppData\\Local\\Programs\\NodeLens\\resources\\mcp-server\\index.js"]
}
}
}
MCP works best for cross-Blueprint analysis — asking Claude to understand how multiple Blueprints interact, find patterns, or generate new logic based on your existing code style.
If you already have a NodeLens project folder from a previous install or another machine, you can load it in seconds.
NodeLens creates a structured snapshot of your Blueprints when you send them from Unreal Engine. These files represent the state of your Blueprint at that moment — they are not a replacement for your Unreal project files.
Always make Blueprint changes in Unreal Engine first. If you update a Blueprint and send it to NodeLens again, the new snapshot will replace the previous NodeLens data. Any manual edits made inside NodeLens will not be preserved.
When using AI features (chat or MCP) to generate or modify Blueprint logic, always save the result to a new folder (for example, Fixes) — never overwrite the original. This keeps your source Blueprint safe from accidental changes.
NodeLens is actively developed and continuously improved. New Unreal Engine workflows, AI capabilities, and quality-of-life improvements are regularly added to make the workflow faster and more powerful.
