Control the Unity Editor application state. You can start, stop, or pause the 'playmode'. Use 'editor-application-get-state' tool to get the current state first.
unity-mcp-cli run-tool editor-application-set-state --input '{
"isPlaying": false,
"isPaused": false
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool editor-application-set-state --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool editor-application-set-state --input-file - <<'EOF' {"param": "value"} EOF
If unity-mcp-cli is not found, either install it globally () or use instead.
Read the /unity-initial-setup skill for detailed installation instructions.
