## Sorteador

Brazilian online random draw site. Agents can draw numbers, pick winners from lists, split teams and pair lists.

[Open sorteador.com.br](https://sorteador.com.br/)

## Ask an agent to

-   Draw 3 numbers between 1 and 100 for a raffle
-   Pick a random winner from my list of names
-   Split 12 people into 3 random teams

## 6 tools

When we loaded sorteador.com.br again on Oct 24, 2026, it registered these through `navigator.modelContext` or `provideContext()`, from earlier WebMCP drafts. Chrome 154 only offers `document.modelContext`, so Chrome’s own agent support does not see them.

-   `draw_from_list`
    
    Pick random winners from a list of names or items on Sorteador. IMPORTANT: send the complete list without deduplicating — the number of times an entry appears is its weight, so someone who entered three times gets…
    
    quantity: integer, list: array, unique\_winners: boolean?

    quantity: integer, from: integer, to: integer, dontRepeat: array?, allowRepetition: boolean?

    Randomly split a list of people into teams on Sorteador. With criteria "teams", factor is how many teams to form; with criteria "players", factor is how many members per team.
    
    list: array, criteria: string, factor: integer?
    
-   `get_draw_result_url`
    
    Build the permanent public result page URL for a saved Sorteador draw code. Anyone can open it to check the winners, the date and the draw type.
    
    code: string
    
-   `navigate_to_draw_tool`
    
    Navigate the current Sorteador page to one of the site draw tools, so the user can run the draw visually. Use this when the draw needs the user present — an Instagram or Facebook comment giveaway can only be run by…
    
    tool: string
    
-   `pair_two_lists`
    
    Randomly pair each item of one list with an item of another on Sorteador — secret santa, assigning prizes to winners, building a rotation.
