api record

csno — a provably-fair arcade for agents, paid in USDC over x402 on Base. Buy chips once, then play coinflip, dice and roulette for free at machine speed and verify every outcome yourself with commit-reveal. Start with csno_games. Buying chips needs a wallet, so csno_buy_chips quotes the payment rather than making it. Full instructions: https://csno.cc/skill.md

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 12 tools

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • csno_games unknown never probed

    List the games csno offers and how to call them. Start here — it also documents the buy-in and verify flow.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • csno_house unknown never probed

    Floor statistics: rounds played, chips in, chips paid out, house profit, and the address the house is paid at.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • csno_free unknown never probed

    Claim 100 free chips — once per address, no payment. Enough to play a few rounds and check a proof before spending anything. `signature` is the same EIP-191 personal_sign of "csno: open a round for {address}" that csno_commit takes; call csno_auth_statement for the exact string. Free chips play and win like any other, but a wallet must buy in at least once before it can cash out. Winnings keep until then.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address",
    "signature"
  ],
  "properties": {
    "address": {

    "signature": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 16 lines
  • csno_balance unknown never probed

    Chip balance for a player's wallet address, and what it's worth in USD. Chips are an IOU held by csno, not on-chain tokens.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address"
  ],
  "properties": {
    "address": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • csno_buy_chips unknown never probed

    Quote the cost of buying chips and return the live x402 payment demand. This tool cannot complete the purchase: paying requires signing an ERC-3009 authorization with a funded wallet, which an MCP client does not have. Use the returned `payment_required` details to pay over x402 (or run scripts/play.py, which does it end to end).

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • csno_commit unknown never probed

    Open a round. csno generates a secret seed and returns ONLY its sha256 commitment — proof it fixed the outcome before seeing your seed. Required before every round; each commitment is good for exactly one. `signature` proves you control `address`: EIP-191 personal_sign of "csno: open a round for {address}". Without it anyone could open rounds against your balance and play it away. Call csno_auth_statement for the exact string to sign.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address",
    "signature"
  ],
  "properties": {
    "address": {
      "type": "string"
    },
    "signature": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 16 lines
  • csno_auth_statement unknown never probed

    The exact string to sign to prove you control an address.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address"
  ],
  "properties": {
    "address": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • csno_flip unknown never probed

    Call heads or tails on a coinflip. `round_id` comes from csno_commit. `client_seed` is YOUR entropy — choose it yourself, it's what stops the house picking a seed that suits it. `call` is "heads" or "tails". Returns the outcome plus the proof needed to verify it.

    mcp-tool

    {
  "type": "object",
  "required": [
    "round_id",
    "client_seed",
    "wager"
  ],
  "properties": {
    "call": {
      "type": "string",
      "default": "heads"
    },
    "wager": {
      "type": "integer"
    },
    "round_id": {
      "type": "string"
    },
    "signature": {
      "type": "string",
      "default": ""
    },
    "client_seed": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 28 lines
  • csno_dice unknown never probed

    Call a 0–100 roll landing under or over `target` (1–99). Longer odds pay more. The payout schedule isn't published — the result tells you what the round returned.

    mcp-tool

    {
  "type": "object",
  "required": [
    "round_id",
    "client_seed",
    "wager",

  "properties": {
    "wager": {
      "type": "integer"
    },
    "target": {
      "type": "integer"
    },
    "round_id": {
      "type": "string"
    },
    "direction": {
      "type": "string",
      "default": "under"
    },
    "signature": {
      "type": "string",
      "default": ""
    },
    "client_seed": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 32 lines
  • csno_roulette unknown never probed

    Spin a European roulette wheel — 37 pockets, 0 to 36. `bet` is the call you're making: straight, red, black, odd, even, low, high, dozen1, dozen2, dozen3, column1, column2, column3. A straight call also needs `number` (0–36). Zero loses every call except a straight on 0. Returns the pocket, its colour, and the proof.

    mcp-tool

    {
  "type": "object",
  "required": [
    "round_id",
    "client_seed",
    "wager",

    "bet": {
      "type": "string"

      "anyOf": [

          "type": "integer"
        },
        {
          "type": "null"
        }
      ],
      "default": null

    "client_seed": {
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 39 lines
  • csno_verify unknown never probed

    Independently re-derive a past round from its revealed seed. Returns whether the revealed seed matches the commitment issued before the round, and whether the recorded roll follows from it. Anyone can call this for any round — that's the point.

    mcp-tool

    {
  "type": "object",
  "required": [
    "bet_id"
  ],
  "properties": {
    "bet_id": {
      "type": "integer"
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • csno_cashout unknown never probed

    Redeem chips for real USDC, sent on-chain to the player's wallet. This is the only path money takes OUT of csno. It settles through the facilitator with the house acting as the x402 client, so it costs no gas on either side. Chips are debited first and refunded if the transfer fails. Returns the transaction hash on success.

    mcp-tool

    {
  "type": "object",
  "required": [
    "address",
    "chips"
  ],
  "properties": {
    "chips": {
      "type": "integer"
    },
    "address": {
      "type": "string"
    },
    "signature": {
      "type": "string",
      "default": ""
    }
  },
  "additionalProperties": false
}

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
