Install

One command:

claude mcp add poker -- npx -y poker-with-claude

That's it. Open Claude Code and say "deal me in".

How to play

Just talk to Claude:

"Deal me in" — starts a new hand
"Call" — match the bet
"Raise 100" — raise the stakes
"All in" — send it
"Fold" — live to fight another hand
"Show my poker stats" — see your career record

How it works

This is an MCP server with 4 tools:

poker_deal — deals a new hand, gives Claude its private hole cards
poker_action — processes the player's action
poker_claude_action — Claude decides and plays its own hand
poker_stats — lifetime win/loss record

Claude sees its own cards but not yours (until showdown). It makes real poker decisions — calling, raising, bluffing, folding — based on hand strength, pot odds, and board texture.

Cards are shuffled with crypto.randomInt() for true randomness. No rigging.

Features

Full Texas Hold'em — preflop, flop, turn, river, showdown
Claude plays for real — the LLM reads its cards and decides its moves
Fair game — Claude can't see your cards, cryptographic shuffle
ASCII poker table — always-visible card UI with phase tracker
Trash talk — Claude has personality
Persistent stats — tracks wins, losses, streaks across sessions

Uninstall
