  CMS publishes first-party client libraries only for the Blue Button 2.0 API (Node, Python, Java) plus
  the QPP measures-data package and the QPP submissions file-upload client. The bulk-FHIR APIs (BCDA,
  AB2D, DPC) ship SAMPLE CLIENTS in the CMSgov org rather than published packages — those are listed
  under samples[], not packages[], because they are not distributed through any registry. The
  @cmsgov/design-system family is a first-party UI component library, captured in
  components/cms-components.yml rather than here.

    version: 11.0.0
    published: '2026-07-21'
    api: CMS Quality Payment Program (QPP) Measures API
    note: >-
      First-party machine-readable MIPS quality / promoting-interoperability / improvement-activity /
      cost measure specifications per performance year, shipped as an npm package. This is the
      distribution channel for the QPP Measures data described at
      https://cmsgov.github.io/qpp-measures-data/.
  - language: javascript
    registry: npm
    name: qpp-file-upload-api-client

    official: true
    version: null
    published: null
    api: CMS Quality Payment Program (QPP) Submissions API
    note: >-
      First-party helper client for the QPP Submissions API file-upload flow. Registry metadata was not
      resolvable at probe time (2026-08-15), so version and published are recorded null rather than
      guessed — checked, nothing to record.
  - language: java
    registry: maven
    name: gov.hhs.cms.bluebutton:bluebutton-parent
    url: https://search.maven.org/artifact/gov.hhs.cms.bluebutton/bluebutton-parent

    version: 1.1.0

    api: CMS Blue Button
    note: >-
      DECAY SIGNAL. The only CMS-owned Maven Central coordinates under gov.hhs.cms.bluebutton were last
      published in 2016 and describe the original Blue Button FHIR server, not a client SDK. The current
      Java client, CMSgov/cms-bb2-java-sdk, is source-only — last pushed 2022-10-18, never released to
      a registry — so a Java consumer of Blue Button 2.0 has no installable first-party artifact and
      must build from a repo that has been untouched for nearly four years while the Node SDK shipped
      eleven releases.
