add_autoload · Godot MCP: Risk & Policy

WHAT IT DOES

What add_autoload does on Godot

AI agents use add_autoload 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.

PARAMETERS

Parameter	Type	Required	Description
`name`	string	Yes	Autoload singleton name
`path`	string	Yes	Script path (e.g. "res://globals.gd")

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why add_autoload needs a policy

This tool creates new autoload entries, which modifies the Godot project configuration file. While reversible (autoloads can be removed), it permanently alters project state and runtime behavior until explicitly undone. Classified as Write rather than Execute because the tool itself doesn't run arbitrary code—it registers a node as autoload, which then executes during game startup.

From the tool's definition Tool name 'add_autoload' combined with description 'Add an autoload entry' indicates creation/modification of project configuration.

Verdict

add_autoload Rate-limited

add_autoload 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.
