Spirit Cards MCP server

Which MCP servers are Spirit Cards's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namefun.spiritcards/spirit-cards-mcpverified in the MCP registry

The registry name sits under spiritcards.fun. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 108 ms.

Should an agent connect itSkip it
  • Its tools do none of the product's use cases we checked: merge cards into evolved forms; stake cards to earn rewards.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • not sure · mine creature cards through proof of work
  • cannot · merge cards into evolved forms
  • cannot · stake cards to earn rewards

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • get_collection_stats

    Live collection statistics for Spirit Cards: total minted, max supply, current mint price (ETH), difficulty (requiredBits/baseBits), cooldown, merge fee, burned/forged counters, paused flag, chainId and contract.

  • get_card

    Full profile of a Spirit Cards token by id: species, element, rarity tier, HP/ATK/DEF, and the deterministic on-chain seed. Works for any minted token id.

  • verify_nonce

    Recompute the proof-of-work for a (miner, nonce) pair exactly as the contract does: work = keccak256(chainId ‖ contract ‖ miner ‖ nonce). Returns the hash, its leading-zero-bit count, the current requiredBits threshold, and whether it…

  • get_leaderboard

    On-chain activity-points leaderboard (mine/merge/stake/pvp-win points), top N wallets.

  • get_pool

    Staking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards.

  • get_recent_activity

    Recent on-chain activity (mints / pack opens) from the latest blocks.

  • get_project_info

    What Spirit Cards is: the game, the five-node loop (mine → merge → battle → stake → points), the chain (Robinhood Chain, CORE contract, explorer, ETH gas), official links, the collection (species / rarity tiers / battle elements) and the…

  • get_mining_guide

    Step-by-step guide to mine a Spirit Card: the exact proof-of-work rule, the live difficulty / price / cooldown / chip discount, where to get a miner (browser at /mine, public CLI), the exact contract call, and how to get a valid nonce…

  • find_nonce

    Grind a proof-of-work nonce for a miner address so it can mint immediately: work = keccak256(chainId ‖ core ‖ miner ‖ nonce), using the live requiredBits threshold. Returns the first nonce whose work has at least requiredBits leading zero…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "spirit-cards-mcp": {
      "type": "http",
      "url": "https://spiritcards.fun/api/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http spiritcards https://spiritcards.fun/api/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://spiritcards.fun/api/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
