Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@RCE CHO SPARQL MCP ServerHow many cultural heritage objects are registered?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
RCE CHO SPARQL MCP Server
MCP server waarmee een LLM het RCE Cultureel Erfgoed SPARQL endpoint kan bevragen. Gebouwd op de CEO ontologie (automatisch geladen van GitHub) en de RCE datamodelregels.
Remote gebruik (geen installatie nodig)
De server draait publiek op Render en is direct te gebruiken:
https://mcp-server-rce-cho-http.onrender.com/mcpClaude Desktop (via mcp-remote proxy)
{
"mcpServers": {
"rce-cho-sparql": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://mcp-server-rce-cho-http.onrender.com/mcp"]
}
}
}Cursor
Voeg toe aan .cursor/mcp.json:
{
"mcpServers": {
"rce-cho-sparql": {
"url": "https://mcp-server-rce-cho-http.onrender.com/mcp"
}
}
}Open WebUI / andere MCP clients
Gebruik de URL direct: https://mcp-server-rce-cho-http.onrender.com/mcp
Let op: de server draait op de gratis Render-tier en kan na 15 minuten inactiviteit sluimeren. De eerste aanroep na een pauze duurt dan 20-30 seconden.

Tool | Beschrijving |
| Geeft de volledige ontologie-context terug (klassen, properties, paden, spelregels). Altijd eerst aanroepen. |
| Voert een SPARQL SELECT/ASK query uit op het endpoint |
| Checkt een query op veelgemaakte fouten vóór uitvoering |
| DESCRIBE op een specifieke URI |
| Geeft de correcte URI voor een Nederlandse provincie |
Hoe het werkt
LLM roept
get_ontology_context()aan → krijgt alle klassen, properties en spelregelsLLM stelt SPARQL query op op basis van de ontologie
LLM roept
validate_query(query)aan → fouten worden geblokkeerdLLM roept
query_sparql(query)aan → resultaten uit de brondataLLM presenteert resultaten in mensentaal
