inputsystem-modify	Generic write escape-hatch: apply a `SerializedMember` diff to the `InputActionAsset` object itself via ReflectorNet `TryModify`, for fields not covered by the dedicated tools. Use 'inputsystem-get' first to inspect the structure.	generated-by mcp-plugin-dotnet

InputSystem / Modify Asset (generic)

Modify an InputActionAsset by applying a SerializedMember diff via ReflectorNet. This is the generic escape hatch for asset-level fields/properties that the dedicated tools do not expose.

Inputs

• assetPath — required. Path to the existing .inputactions asset.
• data — the SerializedMember diff to apply. Route fields through the fields channel and properties through the props channel — ReflectorNet resolves them separately with no cross-fallback.

Behavior

Loads the asset, applies the diff via Reflector.TryModify, and on success re-serializes and saves the asset back to disk. The applied logs are returned. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool inputsystem-modify --input '{
  "assetPath": "string_value",
  "data": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool inputsystem-modify --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool inputsystem-modify --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.

Input

assetPath	string	Yes	'Assets/'-rooted path to the existing '.inputactions' asset.
data	string	Yes	The SerializedMember diff to apply. Fields go through the 'fields' channel; properties through 'props'. RQL: SerializedMember
