summary: >-
  SegmentStream ships no maintained language SDK. Every first-party package that
  reached a registry or a public repository has been archived, and the one npm
  package that still resolves last shipped in 2019 — six and a half years before
  the MCP server it would have to wrap. The live client surface is a
  CDN-distributed browser tracker with no version pin, and the two packages the
  provider currently markets (the CLI and the Cloud TypeScript SDK) are not
  published anywhere. The programmatic surface an integrator actually uses is
  the hosted MCP server (mcp/segmentstream-mcp.yml).

    note: >-
      The only first-party SegmentStream package on any public registry. Latest
      release 1.0.15 (2019-10-25); its GitHub repository is archived. It predates
      the MCP server (launched 2026-02-25) by more than six years and wraps
      nothing in the current product.

    note: >-
      The current, generally-available browser tracker. Distributed only from
      SegmentStream's own CDN — there is no metadata endpoint to query and no
      npm mirror. The URL pins the major version path (/sdk/v1/) but nothing
      finer, so it floats to the latest v1 build: version and published are null
      because the distribution genuinely does not expose them, and a consumer
      cannot determine which build they are serving either. No subresource
      integrity hash is published with the snippet.

      Open-source browser data-collection / dataLayer manager library, the

    note: >-
      Archived on GitHub and never published under a resolvable npm name
      (digital-data-manager and @segmentstream/digital-data-manager both 404 on
      registry.npmjs.org, checked 2026-08-13). Superseded by the CDN tracker.

      Notable only as evidence that SegmentStream once generated clients from an
      OpenAPI document internally. No such specification is published today.

      End-to-end geo-experimental methodology package, underpinning the

    note: >-
      The most recently touched repository in the org, but it is not a
      SegmentStream client library — GeoLift originates with Meta's Marketing
      Science team. Marked official: false because SegmentStream is not the
      author.
