Search the built-in assets of the Unity Editor located in the built-in resources: Resources/unity_builtin_extra. Doesn't support GUIDs since built-in assets do not have them.
unity-mcp-cli run-tool assets-find-built-in --input '{
"name": "string_value",
"type": "string_value",
"maxResults": 0
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool assets-find-built-in --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool assets-find-built-in --input-file - <<'EOF' {"param": "value"} EOF
If unity-mcp-cli is not found, either install it globally () or use instead.
Read the /unity-initial-setup skill for detailed installation instructions.
