Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Neither one's marketplaces publish a list of tools, so there is nothing to compare.

Only io.github.cletcher/chaprola asks for
CHAPROLA_API_KEY (secret)CHAPROLA_USERNAME
Only io.github.faulkj/fhirhydrant asks for
FHIR_ACTIVE_KEY (secret)FHIR_AUTHFHIR_CLIENT_IDFHIR_JWKS_URLFHIR_SERVER_URLFHIR_TOKEN_URLFHIR_VERSIONMCP_TRANSPORT
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
