assets-find-built-in

name	assets-find-built-in
description	Search the built-in assets of the Unity Editor (located at Resources/unity_builtin_extra). Filters by name and/or type; built-in assets have no GUID so GUID-based lookups are not supported.

Assets / Find (Built-in)

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.

Inputs

• name (optional) — case-insensitive name fragment. Underscores, hyphens, spaces, and periods delimit search words so partial-word matching works.
• type (optional) — restrict results to assets assignable to this type (e.g. UnityEngine.Texture2D).
• maxResults — cap on returned list size (default 10).

Ranking

Results are sorted by descending match quality: exact match → substring match → all-words match → partial-words match. Within a rank, results are sorted alphabetically by filename for stable ordering.

How to Call

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.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool assets-find-built-in --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
name	string	No	The name of the asset to filter by.
type	any	No	The type of the asset to filter by.
maxResults	integer	No	Maximum number of assets to return. If the number of found assets exceeds this limit, the result will be truncated.
