KentekenKompas MCP
Read-only Dutch vehicle knowledge, comparisons, terminology and cited sources for AI clients. It is not RDW and does not claim official RDW affiliation. Missing or delayed data is a limitation, not proof of a good or bad vehicle.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
MCP endpoint (Streamable HTTP)
https://api.kentekenkompas.nl/mcpWhat its tools do
7 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

search_vehicle_knowledge
Advertised read-only
Discover public models, existing answers, terms and provenance from free text when no canonical key is known. Use get_model_context, get_answer_context, explain_dutch_vehicle_term or get_source_context for known IDs; compare_vehicle_models for a known model pair; get_fuel_price_context for fuel-source status. Results use deterministic lexical/intent relevance, never AI confidence; no supported match returns data=[] with limitations. Public read-only access; no knowledge writes. Calls consume rate limits.

Advertised read-only
Read model-level knowledge for an exact modelKey; optionally include its existing Direct Answers. Use search_vehicle_knowledge to discover a key, get_answer_context for a known answerId, or compare_vehicle_models for a known pair. Not a license-plate lookup or individual-car assessment. Unknown key returns MODEL_NOT_FOUND; incomplete coverage remains a successful result with coverage and limitations. Public read-only access; no knowledge writes. Calls consume rate limits.

Do not pass a free-text question as an ID. Unknown ID returns ANSWER_NOT_FOUND; preserve the returned evidence and limitations. Public read-only access; no knowledge writes.

Read one stored sourceModelKey-to-targetModelKey relation, not a generated comparison. Returns model keys, relationType/meaning and rationale, with evidence, sources and citations. Preserve classification and limitations; do not strengthen the stored claims. Only DIRECT_ALTERNATIVE denotes a direct alternative. Existing models need not have a relation; the reverse direction is a separate lookup. Use get_model_context for one model and its peers, or search_vehicle_knowledge to discover keys. Unknown model returns MODEL_NOT_FOUND; self/missing relation returns COMPARISON_NOT_AVAILABLE. Public read-only access; no knowledge writes. Calls consume rate limits.

Advertised read-only
Read the existing fuel-price provenance/status, not current pump prices or a vehicle's consumption. No arguments. Currently succeeds with SOURCE_REQUIRED_AT_RUNTIME and prices=[] because no validated current-price adapter is configured. Use get_source_context for an exact source ID or search_vehicle_knowledge for broader fuel knowledge. Never treat empty prices as zero or invent a current price. Public read-only access; no knowledge writes. Calls consume rate limits.
