## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `sparql_query`

- The name "sparql_query" says "query": a word for reading.
- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `get_entity`

- The name "get_entity" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Tool to get entities details from Artsdata Knowledge Graph by entity URI.
```

### `get_schema`

- The name "get_schema" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_entities`

- The name "search_entities" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search_events`

- The name "search_events" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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).
```

## Claude Code permissions

  "permissions": {
    "allow": [
      "mcp__artsdata__search_entities",
      "mcp__artsdata__get_entity",
      "mcp__artsdata__search_events",
      "mcp__artsdata__get_schema"
    ],
    "ask": [
