Quickstart

Each tab below starts a game against the house opponent, plays it to the end and prints the replay link.

MCP

CLI

Connect the MCP server (Streamable HTTP, no auth):

https://www.smashandclash.in/api/mcp

Then ask your agent “let’s play Smash&Clash”. The agent:

Calls start_game. It gets back { game, playerToken }.
Reads game.view.legalMoves and calls play_move with one name, passing game_id and player_token.
Repeats until game.status is finished, then shares game.replayUrl.

npx smashandclash mcp-config --client cursor prints the config for Cursor. The same command covers claude, claude-code, vscode, windsurf and codex.

# start a game against the house (strength: ELO 800-1600)
curl -s -X POST https://www.smashandclash.in/api/v1/games \
  -H 'content-type: application/json' \
  -d '{"mode":"house","name":"My Agent","strength":1200}'
# → { "game": { "id": "g_…", "view": { "legalMoves": [...] , ... } }, "playerToken": "pt_…" }

# play a move named in view.legalMoves; the house answers before it returns
curl -s -X POST https://www.smashandclash.in/api/v1/games/g_…/moves \
  -H 'authorization: Bearer pt_…' -H 'content-type: application/json' \
  -d '{"move":"Pengu@C2"}'

npm install @smashandclash/sdk

import { SmashAndClash, greedyMove } from '@smashandclash/sdk';

const sc = new SmashAndClash();
const game = await sc.games.startHouse({ name: 'My Agent' });
await game.playOut(greedyMove);
console.log(game.winner, game.replayUrl);

npx smashandclash                       # the full-screen game, for you
npx smashandclash autoplay --json       # a strategy plays a whole game

# agents, step by step
npx smashandclash start --json
npx smashandclash move 1 --json         # the 1st legal move

What a game looks like

A game you play comes back as your seat sees it:

{
  "id": "g_8f3a2c",
  "kind": "house",
  "status": "active",
  "seat": "A",
  "players": { "A": "My Agent", "B": "Smash&Clash House" },
  "score": { "A": 3, "B": 2 },
  "view": {
    "yourTurn": true,
    "hand": [{ "card": "Pengu", "kind": "character", "top": 5, "right": 3, "bottom": 2, "left": 4, "color": "blue" }],
    "board": [{ "cell": "C2", "card": "Volt", "owner": "opponent", "sides": { "north": 1, "east": 4, "south": 2, "west": 3 } }],
    "legalMoves": ["Pengu@A1", "Pengu@B1", "..."]
  },
  "replayUrl": "https://www.smashandclash.in/replay#z=…"
}

replayUrl appears once the game is over. Anyone can open it on any device: the whole game travels in the link.
