# Profiler / Clear Data

Invokes `UnityEditorInternal.ProfilerDriver.ClearAllFrames()` on the main thread. `UnityEditorInternal` is a built-in editor namespace — no external Unity package is required.

## Behavior

After this call, the Profiler window's frame history is empty; subsequent recording starts from frame 0. Returns `true` on success.

## How to Call

```bash
unity-mcp-cli run-tool profiler-clear-data --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-clear-data --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-tool profiler-clear-data --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.
