  • Not measured
    Fast (p50)

    Median latency 1057 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1530 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

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.

  • 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 51 parameters have a description (0%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

    Website matches publisher

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

  • Pass
    Source repo linked

    A 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 8

kg_audit_identity

Canonical audit of one existing Wikidata QID against one local identity envelope. Returns contradictions, evidence and uncertainty. Provider agreement is not local identity proof. Google crosscheck is disabled remotely. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_discover_identity

Canonical discovery of one identity from a local evidence envelope. Default 3, maximum 5 candidates. Returns ambiguity and insufficient-evidence states; sameAs candidates are unapproved. Google crosscheck is disabled remotely. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_entity

Bounded structured facts for one Wikidata QID. Arbitrary source prose, aliases, URLs, media and references are withheld. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_lookup_entities

Compact selected Wikidata facts for at most 10 supplied QIDs. Fact lookup does not establish local identity. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_related

Bounded outgoing, inverse or hierarchy relationships for one Wikidata QID. Maximum depth 2 and 10 results. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_resolve

Canonical deterministic resolution of one identity from supplied local facts and Wikidata evidence. Returns identity verdicts and reason codes, including uncertainty. Google is disabled remotely. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_search

Wikidata entity candidates by name, with local place/type filtering. Default 3, maximum 5 candidates. Google and fallback are disabled remotely. New entities use bounded direct-record admission without recursive content certification. Identity evidence and uncertainty remain separate. Public prose, aliases, external links and media are withheld.

Discovered
kg_status

Public remote provider configuration and operational limits. No external provider calls. Wikidata is available; Google Knowledge Graph is disabled.
