/profiler-start

name: profiler-start
description: "Enable Unity's runtime profiler and open the Profiler window. Idempotent: calling when already enabled returns the current enabled state without error."

Profiler / Start

Enables `UnityEngine.Profiling.Profiler.enabled = true` and opens `Window > Analysis > Profiler` via `EditorApplication.ExecuteMenuItem`. Returns `true` once the profiler is enabled.

Behavior

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

Snapshot-based: this tool does not stream historical frame data — use Unity's Profiler window directly for that.

How to Call

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