Assets / Refresh

Refreshes the AssetDatabase. Use it if any file was added or updated in the project outside of Unity API. Use it if need to force scripts recompilation when '.cs' file changed.

Inputs

• options — ImportAssetOptions flag (default ForceSynchronousImport).
• requestId — required for processing-mode responses; the tool returns Processing immediately and delivers a follow-up completion when compilation finishes.

Behavior

Runs AssetDatabase.Refresh(options). If EditorApplication.isCompiling is true after the refresh, schedules a post-compilation notification and returns a Processing response. If compilation already failed (EditorUtility.scriptCompilationFailed), returns Success with the compilation error details. Otherwise returns a plain Success.

How to Call

unity-mcp-cli run-tool assets-refresh --input '{
  "options": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

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

Or pipe via stdin (recommended):

unity-mcp-cli run-tool assets-refresh --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.
