Is KPN Grexx official?

How is the trust score calculated?

This listing scores 52 (Fair). The formula is published on the methodology page.

Environment

Name	Required	Notes
KPN_GREXX_USERNAME	Yes	Grexx API username. Passed to the SDK as the OAuth client_id (portal: API Gegevens). The SDK sends it with HTTP Basic on the token endpoint. This server does not mint the token.
KPN_GREXX_PASSWORD	Yes	Grexx API password. Passed to the SDK as the OAuth client_secret (scope=all). The SDK sends it with HTTP Basic on the token endpoint. Secret.
KPN_GREXX_BASE_URL	Yes	Grexx interface root, without /realtime. Env only — never a gateway header. No default; acceptatie and production differ.
KPN_GREXX_TOKEN_URL	No	OAuth token endpoint. Env only — never a gateway header. Production will differ from acceptatie.
KPN_LEGACY_DEVELOPER_API	No	Set to 1 to also register the developer.kpn.com tools (disturbances, availability, SIM swap, MSM). Default is Grexx only.
KPN_CLIENT_ID	No	Legacy developer.kpn.com project client ID. Used only when KPN_LEGACY_DEVELOPER_API=1.
KPN_CLIENT_SECRET	No	Legacy developer.kpn.com project client secret. Used only when KPN_LEGACY_DEVELOPER_API=1, together with KPN_CLIENT_ID. Secret.
KPN_MSM_CLIENT_ID	No	Optional legacy MSM app ID. Used only when KPN_LEGACY_DEVELOPER_API=1. Must be paired with KPN_MSM_CLIENT_SECRET.
KPN_MSM_CLIENT_SECRET	No	Optional legacy MSM app secret. Used only when KPN_LEGACY_DEVELOPER_API=1, together with KPN_MSM_CLIENT_ID. Secret.
KPN_BASE_URL	No	Legacy developer.kpn.com base URL. Env only. Used only when KPN_LEGACY_DEVELOPER_API=1.
MCP_TRANSPORT	No	Transport mode. Set to 'stdio' for local CLI use; the image defaults to 'http' for gateway hosting.
AUTH_MODE	No	Credential source: 'env' reads KPN_GREXX_* locally, 'gateway' expects X-KPN-Grexx-Username and X-KPN-Grexx-Password. Base URL and token URL stay env-only.
LOG_LEVEL	No	Log verbosity: debug, info, warn, error
