Return GDScript files with class, base class, exported variables, and functions
AI agents call get_script_index to retrieve information from Godot Devtool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and indexes script metadata for inspection purposes. It queries existing data without creating, modifying, or executing code. This is a safe read operation suitable for project analysis and documentation.
From the tool's definition Tool returns GDScript files with metadata (class, base class, exported variables, and functions). No modifications, deletions, or side effects—purely retrieval of project structure information.
Documented attack patterns abuse exactly the kind of access get_script_index 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 get_script_index:
{
"version": "1",
"default": "deny",
"tools": {
"get_script_index": {}
}
}get_script_index is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return GDScript files with class, base class, exported variables, and functions. It is categorised as a Read tool in the Godot Devtool MCP Server, which means it retrieves data without modifying state.
Register the Godot Devtool MCP server in PolicyLayer and add a rule for get_script_index: 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.
get_script_index is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_script_index 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 get_script_index. 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.
get_script_index 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.
