inputsystem-binding-set	Update a Binding's path, groups, interactions and/or processors by index on an Action in a `.inputactions` asset, then save it. Only the supplied fields are changed.	generated-by mcp-plugin-dotnet

InputSystem / Set Binding

Update fields of an existing InputBinding (identified by its index on an InputAction). Only the parameters you provide are applied; the rest are left unchanged. Use 'inputsystem-get' to find the binding index first.

Inputs

• assetPath — required. Path to the existing .inputactions asset.
• mapName / actionName — required. The Action that owns the binding.
• bindingIndex — required. Zero-based index of the binding.
• path — optional new control path.
• groups — optional new control-scheme group(s).
• interactions — optional new interactions.
• processors — optional new processors.

Behavior

Loads the asset, resolves the Action and binding index (failing if out of range), applies each supplied field via the ChangeBinding syntax (WithPath / WithGroups / WithInteractions / WithProcessors), saves and re-imports the asset. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool inputsystem-binding-set --input '{
  "assetPath": "string_value",
  "mapName": "string_value",
  "actionName": "string_value",
  "bindingIndex": 0,
  "path": "string_value",
  "groups": "string_value",
  "interactions": "string_value",
  "processors": "string_value"
}'

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

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

Or pipe via stdin (recommended):

unity-mcp-cli run-tool inputsystem-binding-set --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.
