Zovo Name Wheel MCP

A community MCP server that allows agents to spin an animated wheel to pick random winners, split groups into balanced teams, or generate random numbers using cryptographic randomness. It supports weighted entries and removing winners after selection.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo Name Wheel spins a wheel of names or options (random name picker), splits people into random teams whose sizes differ by at most one, and picks random numbers. Randomness comes from the server's cryptographic generator with unbiased sampling. Use spin_wheel for 'spin the wheel' / wheel spinner / random name picker requests, make_teams for team generators, and pick_random_number for a random number in a range. For fun, classroom, and team decisions only; not for lotteries, gambling, or prize draws that have legal requirements.

spin_wheel — Spin the wheel
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants to spin the wheel, use a wheel spinner or random name picker, pick a random name or option from a list (wheel spinner with names, yes or no wheel, food wheel, custom wheel), or call on people one at a time. Draws 1 or more different winners with cryptographic, unbiased randomness and shows an animated wheel that lands on the winner. Repeated entries (matched ignoring case) or weights give bigger slices. Returns the winners, each entry's chance, and the remaining entries when remove_winners is true. For fun, classroom, and team decisions only; not for lotteries, gambling, or prize draws that have legal requirements. Does not store results between calls.

make_teams — Make random teams
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants a random team generator: split a list of names into random teams or groups by number of teams or by team size, for a class, a game, a workshop, or a sports session. Team sizes differ by at most 1. Optional rules keep certain pairs apart or groups together. Returns each team's members. Does not balance by skill or rating (assignment is random), and is not for scheduling or seating charts. For fun, classroom, and team decisions only; not for lotteries, gambling, or prize draws that have legal requirements.

Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants a random number generator or number wheel: pick one or more random whole numbers between a min and a max (inclusive), with or without repeats, e.g. a random student number or who goes next. Uses cryptographic, unbiased randomness. Do not use for lottery or Powerball numbers, betting, or login credentials and security codes. For fun, classroom, and team decisions only; not for lotteries, gambling, or prize draws that have legal requirements.
