Assets / Copy

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

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.
