assets-copy

name	assets-copy
description	Copy assets at given paths and store them at new paths. Refreshes the AssetDatabase at the end. Use 'assets-find' to locate the source assets first.

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:

unity-mcp-cli run-tool assets-copy --input-file args.json

Or pipe via stdin (recommended):

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.

Input

Name	Type	Required	Description
