What add_raycast does on Godot
AI agents use add_raycast 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 |
|---|---|---|---|
properties | object | — | Raycast properties (target, enabled, collide_with_areas, etc.) |
parent_path | string | Yes | Parent node — '' for scene root |
Parameters from the server's own tool schema.
Why add_raycast is rated Medium
This tool creates (adds) a new RayCast node to a Godot project's scene tree. This is a reversible modification operation—the node can be removed or the project can be reverted. It does not execute arbitrary code, delete data irreversibly, or move money. Among sibling tools (add_animation_track, add_audio_bus, add_input_action, etc.), all follow the same Write pattern.
From the tool's definition Tool name 'add_raycast' and description 'Add a RayCast2D or RayCast3D node' indicate creation of a scene node in Godot engine.
Attacks that exploit this kind of access
The rule that runs add_raycast safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_raycast, this is the rule to start with:
add_raycast stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every add_raycast call is checked against it from then on.
Questions about add_raycast
Add a RayCast2D or RayCast3D node. 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_raycast accepts 2 parameters: properties, parent_path. Required: parent_path. 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_raycast: 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_raycast 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_raycast 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_raycast. 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_raycast is provided by the Godot MCP server (@keeveeg/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
