    Interface TypedCallToolResult<T>

    Typed CallToolResult that constrains structuredContent to T.

    Prefer returning a raw CallToolResult from tool callbacks. Example: { content: [{ type: "text", text: JSON.stringify(data) }], structuredContent: data }.

    interface TypedCallToolResult<
        T extends Record<string, unknown> = Record<string, unknown>,
    > {
        _meta?: { [key: string]: unknown };
        content: ({} | {} | {} | {} | {})[];
        isError?: boolean;
        structuredContent?: T;
        [x: string]: unknown;
    }
