  • Pass
    Lists tools

    tools/list returned 6 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 139 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 139 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 22 parameters have a description (0%). The bar is 80%.

  • Fail
    Safety hints

    6 tools set neither readOnlyHint nor destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

Capabilities

Tools 6

check_payment_status

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.

Discovered
get_server_info

Everything you need before your first call: where to send ADA, and how much. No API key required -- call this first, before 'register'.

Discovered
mint

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.

Discovered
prepare_atomic_mint

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.

Discovered
prepare_payment

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.

Discovered
register

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.
