api record

OpenBoss is one giant piñata with a public health bar that everyone in the world is hitting at the same time. Whoever lands the killing blow is engraved on its grave forever, and that engraving is the only thing anyone wins. The Pixel is a single pixel in a permanent auction.

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.

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.

  • get_boss open 1h ago

    Return the world boss everyone is currently hitting: its name, lore, tier, current and maximum hit points, active affixes, the live momentum multiplier, and how much damage has been dealt. Use this to answer "what is the boss right now", "how much health is left", or before deciding whether to smack it. One boss exists at a time and everyone in the world shares it.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • get_graveyard open 1h ago

    Return bosses that have already been killed, newest first, each with the display name of whoever landed the killing blow. That engraving is permanent and is the only thing anyone actually wins. Use this for "who has killed a boss", "how many bosses have died", or to look up a past boss.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 50,
      "minimum": 1,
      "description": "How many graves to return. Defaults to 10."
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • get_leaderboard open 1h ago

    Return the damage leaderboard for the current boss — display names and total damage, highest first — together with the most recent hits. Use this to answer "who is winning", "who has done the most damage", or to see whether a particular name is on the board. Resets when the boss dies.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "maximum": 20,
      "minimum": 1,
      "description": "How many entries to return. Defaults to 10."
    }
  },
  "additionalProperties": false
}
    arguments 12 lines
  • get_pixel unknown never probed

    Return the current state of The Pixel (thepixel.lol): who owns it, what they paid, its colour, the minimum price to take it, and recent ownership history. Use this for "who owns the pixel" or "what would it cost to buy it". BUYING IT IS NOT AVAILABLE AS A TOOL — a purchase needs a person at the payment page, because a bid that loses a simultaneous takeover is charged in full and refunds nothing. Send the human to https://thepixel.lol to buy.

    mcp-tool

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

    Return every smack pack for sale: id, price in US dollars, how many smacks it buys, and any bonus. Call this before create_checkout so you can tell the person what they are about to pay. Prices are final — no VAT or tax is added at checkout. Also reports the free allowance, so you can mention that trying it costs nothing.

    mcp-tool

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

    Open a Stripe Checkout Session for one smack pack and return its URL. THIS DOES NOT PAY — hand the URL to the person, who opens it and enters their own card. That page is where they are told smacks are not refundable and that there are no prizes and no payouts, which is why it cannot be skipped. Then poll check_purchase with the returned sessionId until it reports paid, and you get a walletToken to spend with smack_boss. Pass an existing walletToken to top that same wallet up instead of starting a new one.

    mcp-tool

    {
  "type": "object",
  "required": [
    "pack"
  ],
  "properties": {
    "pack": {
      "type": "string",
      "description": "Which pack to buy. Call list_packs for the valid ids and prices."
    },
    "walletToken": {
      "type": "string",
      "description": "Optional. A walletToken from an earlier purchase, to add these smacks to that wallet rather than creating a second one."
    }
  },
  "additionalProperties": false
}
    arguments 17 lines
  • check_purchase unknown never probed

    Given the sessionId from create_checkout, report whether the person has paid yet. Once paid, returns a walletToken and the smack balance it holds — pass that token to smack_boss to spend it. Poll every few seconds after sending someone to the checkout URL; card payments settle asynchronously, so "not paid yet" shortly afterwards is normal rather than a failure. Keep the walletToken: it IS the wallet, there is no account behind it, and whoever holds it holds the smacks.

    mcp-tool

    {
  "type": "object",
  "required": [
    "sessionId"
  ],
  "properties": {
    "sessionId": {
      "type": "string",
      "description": "The sessionId returned by create_checkout."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • get_wallet unknown never probed

    Return the smack balance held by a walletToken. Use it to decide whether to keep smacking or to buy another pack.

    mcp-tool

    {
  "type": "object",
  "required": [
    "walletToken"
  ],
  "properties": {
    "walletToken": {
      "type": "string",
      "description": "A walletToken from check_purchase."
    }
  },
  "additionalProperties": false
}
    arguments 13 lines
  • smack_boss unknown never probed

    Land one smack on the current boss and return the damage dealt and the remaining hit points. One swing per call — call it repeatedly to keep hitting. PAID: pass walletToken (from check_purchase) to spend one smack from that wallet. Paid hits are the real thing — they can crit, they take the momentum multiplier, and only a paid hit can land the killing blow and put a name on the grave forever. FREE: pass visitorId instead and it costs nothing. Three per visitorId — the count is held for about thirty days — then FREE_EXHAUSTED, which is the limit working and not a fault. It is NOT an hourly allowance: waiting does not give them back. A free smack can never land the killing blow and free damage is capped per boss, so the engraving stays with somebody who paid for it. Pass one or the other. If both arrive, the wallet is spent.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "maxLength": 24,
      "description": "Optional display name for the public hit feed, the leaderboard, and — on a killing blow — the grave. Visible to everyone, and permanent once engraved."
    },
    "visitorId": {
      "type": "string",
      "maxLength": 128,
      "minLength": 8,
      "description": "For a free smack. A stable identifier you generate once and reuse so the free allowance is tracked. Any opaque string; a UUID is ideal. Nothing personal in it."
    },
    "walletToken": {
      "type": "string",
      "description": "A walletToken from check_purchase. Spends one paid smack. Takes precedence over visitorId."
    }
  },
  "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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.
