B3.2/5.0

Scored across 8 tools

Disambiguation4/5

Most tools have distinct inputs and outputs (search vs. lookup vs. entity vs. related vs. status), but the identity cluster (kg_audit_identity, kg_discover_identity, kg_resolve) is subtly differentiated only by which inputs are supplied and how the verdict is derived. The verbose, almost identical boilerplate appended to every description makes those three harder to separate than they should be.

Naming Consistency4/5

All names share a kg_ prefix and use snake_case consistently, which is easy to read and predict. However, the pattern shifts between verb_noun (kg_audit_identity, kg_search) and bare noun forms (kg_entity, kg_related, kg_status), a minor deviation from a fully predictable convention.

Tool Count5/5

Eight tools is well-scoped for a bounded knowledge-graph lookup and identity server, with each tool covering a recognizable slice (search, entity facts, batch lookup, relationships, identity resolution, status). Nothing feels padded or missing purely on count grounds.

Completeness3/5

The surface covers Wikidata search, lookup, entity facts, relations, identity audit/discovery/resolution and status, so the Wikidata half is reasonably complete for read-only use. But the server is named for Google Knowledge Graph and every description states Google is disabled remotely, plus there are no write/update operations and relationship traversal is capped at depth 2 and 10 results, leaving a notable functional gap versus the advertised scope.

Available Tools

8 tools
kg_audit_identityC
Read-onlyIdempotent
Inspect

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.

Inputs: envelope (required), refresh, max_candidates, google_crosscheck.

kg_discover_identityB
Read-onlyIdempotent
Inspect

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.

Inputs: envelope (required), refresh, max_candidates, google_crosscheck.

kg_entityC
Read-onlyIdempotent
Inspect

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.

Inputs: id (required), lang, props, evidence.

kg_lookup_entitiesB
Read-onlyIdempotent
Inspect

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.

Inputs: qids (required), lang, fields, refresh.

kg_relatedB
Read-onlyIdempotent
Inspect

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.

Inputs: id (required), lang, prop, depth, +3 more.

kg_resolveB
Read-onlyIdempotent
Inspect

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.

Inputs: name (required), city, kind, lang, +17 more.

kg_searchB
Read-onlyIdempotent
Inspect

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.

Inputs: query (required), lang, type, limit, +3 more.

kg_statusB
Read-onlyIdempotent
Inspect

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

Inputs: no named parameters.
