probuilder-get-mesh-info	Inspect a `ProBuilderMesh` — face/vertex/edge counts plus optional face-by-face detail. Use `detail="summary"` for a token-efficient overview, `detail="full"` for detailed face data. Often skippable when other tools accept `faceDirection` semantic selection.	generated-by mcp-plugin-dotnet

Get ProBuilder mesh information

Inspect a ProBuilderMesh — totals (face/vertex/edge counts) plus optional face-by-face detail (per-face vertex positions, edges, semantic direction). The other ProBuilder tools accept faceDirection (semantic selection like "up", "down") — when that suffices, you can skip this call entirely.

Inputs

• gameObjectRef — the GameObject hosting the ProBuilderMesh component.
• detail — Summary (default, cheap overview with face directions) or Full (per-face data).
• includeVertexPositions — Full only. Include each face's vertex positions in the response.
• includeEdges — Full only. Include each face's edges. Default true.
• maxFacesToShow — Full only. Cap on face-detail entries (default 20; pass -1 for all). Keeps the response small for high-face meshes.

Tip

With semantic face selection (faceDirection) available on Extrude / DeleteFaces / SetFaceMaterial and friends, you often don't need this tool — just pass faceDirection="up" etc. directly.

How to Call

unity-mcp-cli run-tool probuilder-get-mesh-info --input '{
  "gameObjectRef": "string_value",
  "detail": "string_value",
  "includeVertexPositions": false,
  "includeEdges": false,
  "maxFacesToShow": 0
}'

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

unity-mcp-cli run-tool probuilder-get-mesh-info --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool probuilder-get-mesh-info --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
gameObjectRef	any	Yes	Reference to the GameObject with a ProBuilderMesh component.
detail	string	No	Detail level for output.
includeVertexPositions	boolean	No	If true, includes detailed vertex positions for each face (only with detail='full').
includeEdges	boolean	No	If true, includes edge information for each face (only with detail='full').
maxFacesToShow	integer	No	Maximum number of faces to include in detail (only with detail='full'). Use -1 for all faces.
