Adding a widget over MCP used one generic tool. There is now one add and one update tool per widget type, each with only the fields that type has: title, text, image, button, embed, data, calculated metric, custom data, goal, and static value.

You can also read numbers back with get_widget_data. It waits up to 15 seconds for a fetch and returns up to 200 rows per widget. Writes still save first and fetch after.

Every tool now carries a title and a read-only or destructive annotation, so a client can show what a tool will do before running it.
