cbros-nft-minting
Registry code: 46417027385fd477
Non-custodial API for minting native Cardano NFTs (CIP-25 metadata). Cardano MAINNET -- real ADA is used for fees and payments.
This server never holds a caller's signing keys and never holds the minted NFT, even momentarily -- every mint pays the operator's fee and sends the NFT to destination_address in the same transaction. You are responsible for signing your own transactions; this requires either direct Cardano key access (pycardano, cardano-cli, MeshJS, Lucid Evolution) or a human operator who can sign on your behalf. If you have no way at all to produce a Cardano signature, these…

- Is cbros-nft-minting live?
- Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
- Is cbros-nft-minting free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does cbros-nft-minting have?
- 6 tools: register, check_payment_status, prepare_payment, mint, prepare_atomic_mint, get_server_info.
- Is cbros-nft-minting 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.

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_server_info open 1h ago
Everything you need before your first call: where to send ADA, and how much. No API key required -- call this first, before 'register'.
{ "type": "object", "title": "get_server_infoArguments", "properties": {} }arguments 5 linesregister unknown never probed
Register a new API key by paying a one-time fee. Pay the registration fee (see get_server_info) from the Cardano address you want your key bound to, sending it to the operator's payment_address, then call this with that transaction's hash. The payment must already be CONFIRMED on-chain (wait ~20-30s after submitting, or check with check_payment_status). One active key per address -- registering twice with the same address fails. Each payment transaction can only be used once, for registration or for a mint, not both.
{ "type": "object", "title": "registerArguments", "required": [ "from_address", "registration_tx" ], "properties": { "from_address": { "type": "string", "title": "From Address" }, "registration_tx": { "type": "string", "title": "Registration Tx" } } }arguments 18 linescheck_payment_status unknown never probed
Check whether a payment transaction is confirmed on-chain yet. Poll this after paying and before calling 'register', 'mint', or trusting a payment_tx you're about to reference -- submitting a transaction does not mean it is confirmed.
{ "type": "object", "title": "check_payment_statusArguments", "required": [ "tx", "api_key" ], "properties": { "tx": { "type": "string", "title": "Tx" }, "api_key": { "type": "string", "title": "Api Key" } } }arguments 18 linesprepare_payment unknown never probed
Build an unsigned transaction that pays the mint fee from from_address to the operator, with change returned to from_address. You (or your human operator) sign and submit it yourself -- this server never sees or holds private keys. Entirely optional: you can send the payment with any tool of your choice and skip this.
{ "type": "object", "title": "prepare_paymentArguments", "required": [ "from_address", "api_key" ], "properties": { "api_key": { "type": "string", "title": "Api Key" }, "from_address": { "type": "string", "title": "From Address" } } }arguments 18 linesmint unknown never probed
Mint an NFT after separately paying the mint fee (see prepare_payment or pay any other way, then wait for on-chain confirmation -- check_payment_status). Pin your asset (and a thumbnail, for video) to IPFS yourself first; this server never stores files. Each payment transaction hash can only be used once -- a failed mint attempt does not consume it, retry with the same payment_tx. You are solely responsible for the content referenced by ipfs_hash.

Build a single transaction that pays the mint fee from from_address AND mints the NFT to destination_address at the same time -- no separate payment step, no payment_tx. Either both happen or neither does. The operator co-signs its own two witnesses (minting policy + its own fee-covering input) before returning the transaction -- inspect it before signing. You then add your own witness for from_address and submit: sign partially_signed_tx directly (cardano-cli 'transaction sign --tx-file <this> --signing-key-file <your key>', or a CIP-30 wallet's signTx(_, true) then merge the witness) and submit it yourself -- this server cannot sign or submit on your behalf. Pin your asset to IPFS yourself first. You are solely responsible for the content referenced by ipfs_hash.
{ "type": "object", "title": "prepare_atomic_mintArguments", "required": [ "ipfs_hash", "nft_name", "from_address", "destination_address", "api_key" ], "properties": { "api_key": { "type": "string", "title": "Api Key" }, "nft_name": { "type": "string", "title": "Nft Name" }, "ipfs_hash": { "type": "string", "title": "Ipfs Hash" }, "asset_kind": { "type": "string", "title": "Asset Kind", "default": "image" }, "description": { "type": "string", "title": "Description", "default": "" }, "from_address": { "type": "string", "title": "From Address" }, "destination_address": { "type": "string", "title": "Destination Address" }, "ipfs_hash_thumbnail": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Ipfs Hash Thumbnail", "default": null } } }arguments 55 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 id46417027385fd477.

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.
