Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package mcp-sparql
Claude Code 
claude mcp add mcp-sparql -- uvx mcp-sparql==0.1.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "mcp-sparql": {

Examples

Query Wikidata:

sparql_query:
  endpoint: "https://query.wikidata.org/sparql"
  query: "SELECT ?item ?itemLabel WHERE { ?item wdt:P31 wd:Q5 . ?item rdfs:label ?itemLabel . FILTER(LANG(?itemLabel) = 'en') } LIMIT 5"

Check if an entity exists:

sparql_ask:
  endpoint: "https://query.wikidata.org/sparql"
  query: "ASK { wd:Q42 wdt:P31 wd:Q5 }"

Validate a query:

sparql_validate:
  query: "SELECT ?s WHERE { ?s ?p ?o }"

List named graphs:

sparql_list_graphs:
  endpoint: "https://query.wikidata.org/sparql"

Get common prefixes:

sparql_get_prefixes:
  endpoint: "https://query.wikidata.org/sparql"
