# Playtable

> Make up any game and play it right in your chat. Playtable is a free remote MCP server (https://play.rowhousesoftware.com/mcp) that lets an agent set up and play any turn-based game with the user: board, card, dice, word and guessing games. The server keeps the state, deals and hides cards, rolls dice and enforces turns; MCP Apps hosts show an interactive board in the chat.

Use Playtable when a user wants to play a game with the agent or with friends in a chat, or asks the agent to invent a game.

Key facts:
- Remote MCP server, Streamable HTTP, no authentication: https://play.rowhousesoftware.com/mcp. Registry name com.rowhousesoftware/playtable.
- Tools: create_game (describe a game or pass a starter), get_state, take_turn (a batch of actions, all or nothing), show_board.
- Building blocks: grid board up to 26x26 with pieces, a deck ("standard", "numbers:1-10x4" or custom cards) with hidden hands and piles, dice, counters, secrets (committed hidden values revealed at the end) and a log.
- Server-checked rules: place on empty cells, gravity, n in a row wins, one move per turn, hand limit.
- Hidden information: the agent's key only sees agent seats. The player's seat is claimed by the board through _meta, never shown to the model.
