How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1859 tokens (~309/item across 6 items; 5 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_entity ~101
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_schema ~129
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.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| about | object | yes | – |
| classes | array | yes | – |
| conventions | array | yes | How to read the digest and write SPARQL against the graph. |
| prefixes | object | yes | Prefix name -> namespace IRI. |
| vocabularies | array | yes | – |
No examples provided.
search_entities ~248
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.
| Name | Type | Req | Description |
|---|---|---|---|
| in_scheme | array | – | Optional list of Artsdata controlled vocabulary (skos:ConceptScheme) URIs (e.g., ['http://kg.artsdata.ca/resource/ArtsdataEventTypes']). Paired with types: ['http://www.w3.org/2004/02/skos/core#Conce… |

|---|---|---|---|
| results | array | yes | – |
No examples provided.
search_events ~683
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.
| Name | Type | Req | Description |
|---|---|---|---|
| artists | array | – | Optional list of Artsdata artist URIs (e.g., ["http://kg.artsdata.ca/resource/K2-6574"]). If you only have a name, use search_entities (types: ['http://kg.artsdata.ca/ontology/Person']) to find its U… |
| has_event_type_concept | array | – | Optional list of concept URIs from the Artsdata Event Types vocabulary (http://kg.artsdata.ca/resource/ArtsdataEventTypes). Must be valid concept URIs (e.g., http://kg.artsdata.ca/resource/ClassicalM… |
| language | string | – | Language for the labels in the response (e.g. 'en', 'fr'); default is 'en'. This selects the output language only — it does NOT filter events by the language they are performed in. |
| limit | integer | – | Number of results to return. |
| organizations | array | – | Optional list of Artsdata organization URIs (e.g., ["http://kg.artsdata.ca/resource/K5-72"]). If you only have a name, use search_entities (types: ['http://kg.artsdata.ca/ontology/Organization']) to… |
| places | array | – | Optional list of Artsdata VENUE URIs (e.g., ["http://kg.artsdata.ca/resource/K11-2"]) for a theatre, hall, auditorium, room or stage. Only venue URIs work: a city, region or country (e.g. 'Toronto',… |
| startDateFrom | string | – | Optional lower bound filter. Includes events starting on or after this date/time. ISO 8601 format (YYYY-MM-DD or YYYY-MM-DDTHH:mm:ssZ). |
| startDateTo | string | – | Optional upper bound filter. Includes events starting on or before this date/time. ISO 8601 format (YYYY-MM-DD or YYYY-MM-DDTHH:mm:ssZ). |
| Name | Type | Req | Description |

| results | array | yes | – |
No examples provided.
sparql_query ~311
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.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | A complete SPARQL 1.1 SELECT or ASK query, with a PREFIX declaration for every prefix it uses. Build it from the classes, properties and prefixes returned by get_schema, and add a LIMIT. |
| Name | Type | Req | Description |
|---|---|---|---|
| boolean | boolean | – | The answer to an ASK query. |
| head | object | yes | – |
| results | object | – | – |
| truncated | boolean | – | Present and true when the endpoint returned more rows than the server's row cap and only the first rows are included. Add or lower the LIMIT, or page with OFFSET. |
