Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 476 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name lightyear-cryptopunks.

  • Pass
    Lists tools

    tools/list returned 11 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 476 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 476 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.

  • Pass
    Parameters documented

    20 of 21 parameters have a description (95%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Fail
    Recently updated

    Updated 2026-03-30T09:20:39.722919Z, which is older than 180 days.

Capabilities

Tools 11

browse_traits

List all CryptoPunk traits with their counts. Optionally filter by type to see how many punks of that type have each trait. Rate limit: 10 per 10 min (read bucket — shared with browse_types, get_punk_details, get_listings, get_floor_price, get_bids_for_punk, get_bids_for_merkle_root).

Discovered
browse_types

List all CryptoPunk type categories with their counts. Rate limit: 10 per 10 min (read bucket — shared with browse_traits, get_punk_details, get_listings, get_floor_price, get_bids_for_punk, get_bids_for_merkle_root).

Discovered
compute_merkle_root

Compute the Merkle root for a set of CryptoPunk IDs. The root matches the on-chain Solady MerkleProofLib encoding used by the Stash contract. Rate limit: 5 per 10 min (compute bucket — shared with filter_punks, resolve_merkle_root).

Discovered
filter_punks

Filter CryptoPunks by type and traits. Returns matching punk IDs and their Merkle root. Rate limit: 5 per 10 min (compute bucket — shared with compute_merkle_root, resolve_merkle_root).

Discovered
get_bid_recommendation

Analyze market data and recommend a bid price range for a CryptoPunk trait selection. Combines floor price, competing bids, and set composition into actionable guidance. `composition` lists only the traits that define the selection; use `absentTraits` for a full exclusion list when needed. Rate limit: 1 per 1 min (recommend bucket).

Discovered
get_bids_for_merkle_root

Get pending EIP-712 bids matching a specific Merkle root. Useful for seeing competition on a trait-based bid set. Rate limit: 10 per 10 min (read bucket — shared with browse_types, browse_traits, get_punk_details, get_listings, get_floor_price, get_bids_for_punk).

Discovered
get_bids_for_punk

Get pending EIP-712 bids that include a specific CryptoPunk. Returns bids from the CryptoPunks Bids API. Rate limit: 10 per 10 min (read bucket — shared with browse_types, browse_traits, get_punk_details, get_listings, get_floor_price, get_bids_for_merkle_root).

Discovered
get_floor_price

Get the current floor ask price from the native CryptoPunks marketplace. Excludes restricted (onlySellTo) and zero-value listings. Returns `totalActive` (same denominator as get_listings). Rate limit: 10 per 10 min (read bucket — shared with browse_types, browse_traits, get_punk_details, get_listings, get_bids_for_punk, get_bids_for_merkle_root).

Discovered
get_listings

Get currently listed CryptoPunks from the native marketplace. By default returns only publicly buyable listings (excludes restricted onlySellTo and zero-value entries); pass `includeRestricted: true` to include private bundle sales. Optionally filter by price range. Returns `totalActive` (publicly buyable listings, same denominator as get_floor_price) and `matchedCount` (after your filters). Rate limit: 10 per 10 min (read bucket — shared with browse_types, browse_traits, get_punk_details, get_floor_price, get_bids_for_punk, get_bids_for_merkle_root).

Discovered
get_punk_details

Get metadata for specific CryptoPunks: type, traits with rarity percentages, and permalink. Rate limit: 10 per 10 min (read bucket — shared with browse_types, browse_traits, get_listings, get_floor_price, get_bids_for_punk, get_bids_for_merkle_root).

Discovered
resolve_merkle_root

Reverse-engineer a Merkle root back to its punk IDs and inferred trait selection. ONLY works for roots that already have at least one bid in the CryptoPunks Bids API — this tool looks bids up by root, then derives trait config from the resulting punk set. Returns `resolved: false` for unknown roots; constructing a root locally and passing it here will not work. Rate limit: 5 per 10 min (compute bucket — shared with filter_punks, compute_merkle_root).
