Imposter Game MCP Server 🕵️‍♂️

The official Model Context Protocol (MCP) server for playing the Imposter Game (Spyfall alternative) directly with AI.

Powered by Imposter Game Word Generator.

🎮 What is the Imposter Game?

The Imposter Game (also known as Spyfall or Chameleon) is a popular social deduction party game. In the game, everyone receives a secret word (e.g., "Coffee"), except for one player (the Imposter) who receives a slightly different word (e.g., "Tea"). Players take turns asking questions to figure out who the Imposter is, while the Imposter tries to blend in.
