Create, list, and edit TileMapLayer or legacy TileMap nodes
AI agents use tilemap to create or update resources in Godot Devtool — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot Devtool environment.
The tool primarily performs reversible modifications to game scene data (creating and editing tilemap nodes). While 'list' is a read operation, the explicit mention of 'create' and 'edit' establishes this as a Write tool.
From the tool's definition Tool description states "Create, list, and edit TileMapLayer or legacy TileMap nodes". The verbs 'create' and 'edit' indicate data modification capabilities. 'List' is read-only but is secondary to the write operations.
Documented attack patterns abuse exactly the kind of access tilemap gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Godot Devtool, and nothing reaches the server without passing your rules. This is the rule we recommend for tilemap:
{
"version": "1",
"default": "deny",
"tools": {
"tilemap": {
"limits": [
{
"counter": "tilemap_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}tilemap 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.

Create, list, and edit TileMapLayer or legacy TileMap nodes. It is categorised as a Write tool in the Godot Devtool MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Godot Devtool MCP server in PolicyLayer and add a rule for tilemap: 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 Devtool. Nothing to install.
tilemap 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 tilemap 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 tilemap. 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.
tilemap is provided by the Godot Devtool MCP server (wangdiandao/godot-devtool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
