io.github.3121n/udir-mcp — MCP Server for Developer Tools

@nor-data/udir-mcp

MCP-server som wrapper UDIRs åpne registre — bygget for Nabodata-kartleggingen (#4: skoler/barnehager).

NSR (Nasjonalt skoleregister): https://data-nsr.udir.no/v3
NBR (Nasjonalt barnehageregister): https://data-nbr.udir.no/v3

Begge er åpne, auth-frie REST-API-er.

Verktøy

Verktøy	Beskrivelse
`sok_skole`	Skoler per kommune (4-sifret kommunenr, normaliserer ledende null). Filter: navn-delstreng, type (grunnskole/videregaaende/privat/offentlig/spesialskole), inkluder_inaktive
`hent_skole`	Full detalj per orgnr: adresse, koordinater (lat/lon, GeoNorge), elevtall, ansatte-intervall, målform, kontakt
`sok_barnehage`	Barnehager per kommune. Filter: navn, eierform (privat/offentlig), inkluder_inaktive
`hent_barnehage`	Full detalj per orgnr: adresse, koordinater, eierform, kategorier

Datakvalitets-merknader (verifisert 6. juni 2026)

UDIR leverer {Lengdegrad:0, Breddegrad:0, GeoKilde:"Undefined"} for ikke-geokodede enheter — serveren behandler dette som manglende koordinat (utelater feltet).
Navn-queryparam på /v3/enheter ignoreres av UDIR — navnefilter gjøres derfor klientside per kommune.
Registrene inneholder test-enheter (orgnr U999…, kommune 2599) — filtreres implisitt bort ved kommune-søk.

Bygg & test

npm install && npm run build
npm test   # E2E med ekte UDIR-kall (11 sjekker)

Nabodata-bruk

sok_grunnkrets (kartverket) → kommunenr → sok_skole/sok_barnehage → hent_* for koordinater → avstandsberegning klientside. Fremtidig fase B: skoler_naer_punkt med batch-detaljhenting og haversine-radius.
