Assets / Copy
Copy assets at given paths and store them at new paths. Does AssetDatabase.Refresh() at the end. Use 'assets-find' tool to find assets before copying.
Inputs
- `sourcePaths` — paths of the assets to copy.
- `destinationPaths` — paths to store the copied assets (must match `sourcePaths` length).
Behavior
Each source/destination pair is copied in order. Per-pair errors are accumulated in the response instead of throwing, so a single bad pair does not abort the whole batch.
How to Call
unity-mcp-cli run-tool assets-copy --input '{
"sourcePaths": "string_value",
"destinationPaths": "string_value"
}'> For complex input (multi-line strings, code), save the JSON to a file and use: > ```bash > unity-mcp-cli run-tool assets-copy --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > unity-mcp-cli run-tool assets-copy --input-file - <<'EOF' > {"param": "value"} > EOF > ```
Troubleshooting
If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead. Read the /unity-initial-setup skill for detailed installation instructions.

Open skill - /assets-create-folder
Create a new folder under a parent folder inside 'Assets/'. The parent path must start with 'Assets/' and every intermediate folder in it must already exist. Refreshes the AssetDatabase at the end and returns the GUID(s) of the created folder(s).

Open skill - /assets-find-built-in
Search the built-in assets of the Unity Editor (located at Resources/unity_builtin_extra). Filters by name and/or type; built-in assets have no GUID so GUID-based lookups are not supported.
Open skill - /assets-find
Search the Unity asset database using a search filter string. The filter accepts names, labels (`l:`), types (`t:`), AssetBundles (`b:`), areas (`a:`), and globs (`glob:`). See the body for the full filter syntax.
