Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 136 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name z1n.

  • 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 136 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 136 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 7 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.

  • Not measured
    Website matches publisher

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

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

z1n_get_action_state

What one Key can do right now, with reasons. Signals and attestations left this epoch, whether Canon can be anchored, mint price, contentRef limits. Read this before building any transaction — it replaces combining four endpoints.

Discovered
z1n_get_attestable_signals

Signals inside their attestation window right now. Pass keyId to remove the ones that would revert: your own wallet's signals, ones this wallet already attested, and signals that hit the 21 Key-attestation cap.

Discovered
z1n_get_key

One Key: glyphs, owner, signal and attestation counts, recent signals.

Discovered
z1n_get_protocol_state

Current Z1N field state: epoch, totals, mint price, contract addresses.

Discovered
z1n_list_signals

Signals, filterable by key and epoch range. Never returns full history.

Discovered
z1n_verify_index

On-chain vs indexed delta per entity. Check before trusting indexed data.
