name: profiler-get-memory-stats
description: Return memory statistics snapshot from UnityEngine.Profiling.Profiler — reserved, allocated, mono heap, graphics, etc. (in MB).

Profiler / Get Memory Stats

Reads UnityEngine.Profiling.Profiler scalar memory counters and converts each from bytes to megabytes (`/1048576f`).

Fields

• `TotalReservedMemoryMB` — `GetTotalReservedMemoryLong()`.
• `TotalAllocatedMemoryMB` — `GetTotalAllocatedMemoryLong()`.
• `TotalUnusedReservedMemoryMB` — `GetTotalUnusedReservedMemoryLong()`.
• `MonoHeapSizeMB` — `GetMonoHeapSizeLong()`.
• `MonoUsedSizeMB` — `GetMonoUsedSizeLong()`.
• `TempAllocatorSizeMB` — `GetTempAllocatorSize()`.
• `GraphicsMemoryMB` — `GetAllocatedMemoryForGraphicsDriver()`.
• `MaxUsedMemoryMB` — `maxUsedMemory`.
• `UsedHeapSizeMB` — `usedHeapSizeLong`.

Behavior

Uses only built-in Unity APIs (`UnityEngine.Profiling.Profiler`). No external Unity package is required.

How to Call

unity-mcp-cli run-tool profiler-get-memory-stats --input '{
  "nothing": "string_value"
}'

> For complex input (multi-line strings, code), save the JSON to a file and use: > ```bash > unity-mcp-cli run-tool profiler-get-memory-stats --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > unity-mcp-cli run-tool profiler-get-memory-stats --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.
