What write_path_curve does on Godot
AI agents use write_path_curve 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 |
|---|---|---|---|
path | object | — | Path node name (first found if omitted) |
closed | object | — | Whether the curve is closed |
points | array | Yes | Control points as arrays of [x, y, z] (Path3D) or [x, y] (Path2D) |
scene_path | string | Yes | Path to .tscn scene containing a Path2D/Path3D node |
bake_resolution | object | — | Curve bake resolution |
Parameters from the server's own tool schema.
Why write_path_curve is rated Medium
Modifies scene data reversibly by writing curve data to path nodes without deletion or irreversible effects.

The rule that runs write_path_curve 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 write_path_curve, this is the rule to start with:
write_path_curve 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 write_path_curve call is checked against it from then on.
Questions about write_path_curve
Write a curve into a Path2D/Path3D node in a scene. 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.
write_path_curve accepts 5 parameters: path, closed, points, scene_path, bake_resolution. Required: points, scene_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 write_path_curve: 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.
write_path_curve 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 write_path_curve 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 write_path_curve. 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.
write_path_curve 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.
