- Is spirit-cards live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is spirit-cards free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does spirit-cards have?
- 9 tools: get_card, get_pool, verify_nonce, get_recent_activity, get_project_info, find_nonce, get_collection_stats, get_leaderboard, ….
- Is spirit-cards safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid
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_collection_stats open 1h ago
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.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {} }arguments 5 linesget_leaderboard open 1h ago
On-chain activity-points leaderboard (mine/merge/stake/pvp-win points), top N wallets.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "limit": { "type": "integer", "default": 25, "maximum": 200, "minimum": 1, "description": "Max rows (1–200)" } } }arguments 13 linesget_mining_guide open 1h ago
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 with the find_nonce tool.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {} }arguments 5 linesget_card unknown never probed
Full profile of a Spirit Cards token by id: species, element, rarity tier, HP/ATK/DEF, and the deterministic on-chain seed. Works for any minted token id.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "tokenId" ], "properties": { "tokenId": { "type": [ "string", "number" ], "description": "Token id (unsigned integer)" } } }arguments 16 linesget_pool unknown never probed
Staking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {} }arguments 5 linesverify_nonce unknown never probed
Recompute the proof-of-work for a (miner, nonce) pair exactly as the contract does: work = keccak256(chainId ‖ contract ‖ miner ‖ nonce). Returns the hash, its leading-zero-bit count, the current requiredBits threshold, and whether it would be accepted on-chain.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "miner", "nonce" ], "properties": { "miner": { "type": "string", "description": "Miner address (0x…)" }, "nonce": { "type": [ "string", "number" ], "description": "Nonce (unsigned integer)" } } }arguments 21 linesget_recent_activity unknown never probed
Recent on-chain activity (mints / pack opens) from the latest blocks.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": { "limit": { "type": "integer", "default": 10, "maximum": 50, "minimum": 1, "description": "Max events (1–50)" } } }arguments 13 linesget_project_info unknown never probed
What Spirit Cards is: the game, the five-node loop (mine → merge → battle → stake → points), the chain (Robinhood Chain, CORE contract, explorer, ETH gas), official links, the collection (species / rarity tiers / battle elements) and the key economy (max supply, price step, fee split). Call get_mining_guide to start mining.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "properties": {} }arguments 5 linesfind_nonce unknown never probed
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 bits, within a ~20 s wall-clock cap. If the difficulty is high it may return found:false — retry or lower maxAttempts.
{ "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "miner" ], "properties": { "miner": { "type": "string", "description": "Miner address (0x…)" }, "maxAttempts": { "type": "integer", "default": 1000000, "maximum": 5000000, "minimum": 1000, "description": "Maximum number of nonces to try (1000–5,000,000)" } } }arguments 20 lines
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.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id9c2c05f9d61bde4e.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/9c2c05f9d61bde4e/claim.
Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
