ToolAnnotations

Optional properties describing a tool's behavior, per the MCP spec's ToolAnnotations. All hints are advisory and optional; a hint that is left null is omitted from the serialized form (and clients SHOULD treat its absence as "unspecified" rather than a particular default).

@safe

struct ToolAnnotations {

Nullable!string title;

Nullable!bool readOnlyHint;

Nullable!bool destructiveHint;

Nullable!bool idempotentHint;

Nullable!bool openWorldHint;

bool empty();

}

Members

Functions

empty bool empty(): True if no hint is set (serializes to an empty object).

Variables

destructiveHint Nullable!bool destructiveHint;: if true, the tool may perform destructive updates
idempotentHint Nullable!bool idempotentHint;: if true, repeated calls with the same args have no additional effect
openWorldHint Nullable!bool openWorldHint;: if true, the tool interacts with an "open world" of external entities
readOnlyHint Nullable!bool readOnlyHint;: if true, the tool does not modify its environment
title Nullable!string title;: human-readable title for display
