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:

unity-mcp-cli run-tool profiler-get-memory-stats --input-file args.json

Or pipe via stdin (recommended):

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.
