Assets / Create Folder

Creates a new folder in the specified parent folder. The parent folder string must start with the 'Assets' folder, and all folders within the parent folder string must already exist. For example, when specifying 'Assets/ParentFolder1/ParentFolder2/', the new folder will be created in 'ParentFolder2' only if ParentFolder1 and ParentFolder2 already exist. Use it to organize scripts and assets in the project. Does AssetDatabase.Refresh() at the end. Returns the GUID of the newly created folder, if successful.

Inputs

• inputs — list of {ParentFolderPath, NewFolderName} entries. Each entry is processed independently; per-entry errors are collected in the response so a single bad input does not abort the batch.

Validation

• NewFolderName must be non-empty and must not contain any of /, \, <, >, :, ", |, ?, *, or control characters (these checks are cross-platform even on Linux/Mac).
• ParentFolderPath must already exist as an AssetDatabase.IsValidFolder path.
• A folder with the same target name must not already exist under the parent.

How to Call

unity-mcp-cli run-tool assets-create-folder --input '{
  "inputs": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use: ``bash unity-mcp-cli run-tool assets-create-folder --input-file args.json ``

>

Or pipe via stdin (recommended): ``bash unity-mcp-cli run-tool assets-create-folder --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.
