What simplify_polygon does on Godot
AI agents use simplify_polygon 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 |
|---|---|---|---|
points | array | Yes | Array of [x, y] points to simplify |
tolerance | object | — | Douglas-Peucker tolerance (higher = more aggressive) |
Parameters from the server's own tool schema.
Why simplify_polygon is rated Medium
Modifies polygon data reversibly through simplification algorithm, writing changes back.
From the tool's definition Simplify polygon, write it back
Attacks that exploit this kind of access
The rule that runs simplify_polygon 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 simplify_polygon, this is the rule to start with:
simplify_polygon 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 simplify_polygon call is checked against it from then on.
Questions about simplify_polygon
Simplify a polygon via Douglas-Peucker and write it back. 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.
simplify_polygon accepts 2 parameters: points, tolerance. Required: points. 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 simplify_polygon: 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.
simplify_polygon 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 simplify_polygon 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 simplify_polygon. 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.
simplify_polygon 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.
