Return a lightweight godot-devtool tool catalog by default, with optional filtered input schemas by route group, transport, risk level, tool name, or query
AI agents call get_capabilities 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.
get_capabilities is a metadata/introspection endpoint that retrieves tool information and schemas. It performs no mutations, executions, or external operations. Filtering and returning capability data is a classic Read operation.
From the tool's definition Tool returns a 'lightweight godot-devtool tool catalog' with 'optional filtered input schemas' — a pure data retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_capabilities 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_capabilities:
{
"version": "1",
"default": "deny",
"tools": {
"get_capabilities": {}
}
}get_capabilities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return a lightweight godot-devtool tool catalog by default, with optional filtered input schemas by route group, transport, risk level, tool name, or query. 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_capabilities: 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_capabilities 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_capabilities 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_capabilities. 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_capabilities 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.
