AI agents use add_input_binding to create or update resources in Godot — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
key | object | — | Keyboard key name (e.g. "Space", "A", "Escape") — uses physical keycode |
action | string | Yes | Existing input action name |
device | object | — | Device ID (-1 for all) |
joypad_axis | object | — | Joypad axis (e.g. "left_x", "right_trigger") |
mouse_button | object | — | Mouse button index (1=left, 2=right, 3=middle) |
joypad_button | object | — | Joypad button index |
Parameters from the server's own tool schema.
This tool creates or modifies input action bindings, which is a reversible configuration change. It does not execute code, delete data, or trigger external operations—it simply adds a binding entry to the input map.
From the tool's definition Tool name 'add_input_binding' and description 'Add key/mouse/joypad binding to action' indicate creation/modification of input configuration settings in Godot Engine.
Attacks that exploit this kind of access
Add key/mouse/joypad binding to action. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
add_input_binding accepts 6 parameters: key, action, device, joypad_axis, mouse_button, joypad_button. Required: action. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for add_input_binding: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot. Nothing to install.
add_input_binding is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the add_input_binding rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for add_input_binding. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
add_input_binding is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
add_input_binding is one line of Godot's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
