Artsdata tools (5, 1 write)

write = sends, deletes, buys or posts
  • get_entityFree

    Tool to get entities details from Artsdata Knowledge Graph by entity URI. Entity URIs end in the Artsdata ID (K\d+-\d+, e.g. K12-345); cite it with the entity name. The result's `sources` lists the datasets the entity was built from: name them when you answer about the entity, linking `url` when present, else by `name`.

  • get_schemaFree

    Returns the data model of the Artsdata Knowledge Graph: its entity classes (Event, Place, Organization, Person, LivePerformanceWork...), the properties of each with required/optional, cardinality, value types, linked classes and allowed values, the controlled vocabularies, the SPARQL prefixes, and conventions for querying. Derived from the Artsdata Ontology and the Artsdata CORE graph SHACL shapes. Call this before writing a SPARQL query to run with sparql_query against https://query.artsdata.ca/query, since Artsdata's model is not general knowledge. Takes no input.

  • search_entitiesFree

    Tool to search for entities in the Artsdata knowledge graph by name, with optional filters on entity type and on the controlled vocabulary (skos:ConceptScheme) a concept belongs to. Each result has a markdown-link `label` like '[Name (K12-345)](https://kg.artsdata.ca/resource/K12-345)': use it verbatim when mentioning the entity.

  • search_eventsFree

    Tool to search for events in the Artsdata knowledge graph by place, artist, organization, has_event_type_concept and language. Places, artists and organizations are Artsdata entity URIs; the has_event_type_concept filter takes concept URIs from the Artsdata Event Types vocabulary (adr:ArtsdataEventTypes), not schema.org classes. Resolve any name or label to its URI with search_entities first. Places must be venues; for events in a city or region, use sparql_query (see the places parameter). At least one filter is required. Entity URIs end in the Artsdata ID (K\d+-\d+, e.g. K12-345); cite it with the entity name.

  • sparql_querywrite actionFree

    Runs a read-only SPARQL 1.1 SELECT or ASK query against the Artsdata Knowledge Graph (https://query.artsdata.ca/query) and returns the result as SPARQL 1.1 Query Results JSON, exactly as the endpoint returns it: head.vars and results.bindings for SELECT, boolean for ASK. Call get_schema first and build the query from the classes, properties, prefixes and conventions it returns, since Artsdata's model is not general knowledge. Declare every PREFIX you use and always add a LIMIT: at most 1000 rows are returned (the rest is cut and truncated is true; page with OFFSET), and a query gets 25 seconds. If the endpoint rejects the query, its error message is returned so you can fix the query and retry. For the details of an entity URI in the results use get_entity; to find an entity's URI from its name use search_entities. Always SELECT the entity URI next to its label so its Artsdata ID can be cited. Entity URIs end in the Artsdata ID (K\d+-\d+, e.g. K12-345); cite it with the entity name. To find who claims a property value, see the sources guidance in the get_schema conventions.

Calls to /mcp are reported to Google Analytics 4.

MCP resources

latest Artsdata core-minus-provenance dump — the core graph with provenance and RDF-star annotations removed, published monthly as a gzipped Turtle file.

  • artsdata://dumps/core-minus-provenance/latest (artsdata_dump): manifest for the

resources/read asks the Artsdata Databus for the newest version of the artifact (GET /databus/artifact/latest?artifact=) and returns a small JSON document with the download URL, version, format and compression — never the dump contents. Going through the Databus means MCP clients need to know nothing about where the file is actually stored. Clients download the file from downloadUrl and compare version across reads to detect when a new dump lands.

Usage analytics

Calls to /mcp are reported to Google Analytics 4, including the tool used, how long the call took, and the caller's User-Agent. Reporting stays off until both variables below are set, so development and CI need no configuration.
