  Unbounce publishes NO first-party client SDK in any package registry. Every client
  library found is community-maintained and long stale — the newest first release of
  any of them predates the current API version's own docs revision. The only
  first-party distributable Unbounce ships for developers is the agent plugin below,
  which is a plugin manifest pointing at the hosted MCP server, not a client library,
  so no SDKs pointer is emitted for this provider.

    First-party Claude Code / Cowork and ChatGPT / Codex plugin marketplace. Distributed
    from GitHub only — no npm/PyPI package exists — so there is no registry metadata
    endpoint; version read from plugins/unbounce-mcp/.claude-plugin/plugin.json and the
    date from the repository's last push. Not a client SDK: it only wires an MCP client
    to https://mcp.unbounce.com/mcp.

    The project README documents `npm install unbounce-api`, but registry.npmjs.org
    returns {"error":"Not found"} for that name — the package was never published (or
    has been unpublished). Recorded as a checked gap, not a guess.
