  ClosedLoop AI publishes NO client SDK for the /v1 REST API. Its documentation shows raw curl
  against api.closedloop.sh and contains no SDK or client-library section. What it does publish on
  npm is two first-party command-line/agent tools under the @closedloop-ai scope. Both predate the
  current API (spec v1.8.0) and neither is referenced from any current documentation page, so they
  are recorded as published-but-undocumented. PyPI has no closedloop package. The distribution the
  provider actually documents -- the closedloop-skills Claude Code plugin -- ships through the
  Anthropic community plugin marketplace, which is not a package registry and has no version
  metadata endpoint; it is recorded below with version: null for that reason.
packages:

  registry: npm
  url: https://www.npmjs.com/package/@closedloop-ai/mcp-client
  official: true
  official_basis: >-
    Same @closedloop-ai npm scope and same sole maintainer (jirikobelka) as @closedloop-ai/cli,
    whose package author email is team@closedloop.sh; package author is "ClosedLoop AI" and the
    repository is github.com/closed-loop-ai, the GitHub account whose profile blog is
    https://closedloop.sh.

  published: '2026-02-22'
  repository: https://github.com/closed-loop-ai/mcp-client
  repository_status: 404
  note: >-
    Published 2026-02-22, six months before the current API spec (v1.8.0) and the hosted MCP the
    docs prescribe. No current documentation page references it -- every MCP setup path in the docs
    points at the hosted URL https://mcp.closedloop.sh instead. Its declared GitHub repository
    returns 404, so the source is not public.

  repository: https://github.com/closed-loop-ai/closedloop-cli
  repository_status: 404
  note: >-
    Last published 2025-10-17 -- roughly ten months before the /v1 spec version this repo captured,
    and it is at 0.2.x. No documentation page mentions a CLI. Declared repository returns 404.
    Treated as an abandonment signal, not a current SDK.

  version_note: >-
    Checked, nothing to record. The Anthropic community plugin marketplace is not a package registry
    and exposes no version or publish-date metadata endpoint for a plugin, and the provider's install
    snippet is unpinned (`closedloop-skills@claude-community` floats to whatever the marketplace
    currently holds). A consumer cannot tell which revision they are installing either.
  note: ~25 pre-built Claude Code skills documented at https://closedloop.sh/docs/skills/overview.

false_positives:
- name: closedloop
  registry: npm
  version: 0.2.1
  reason: >-
    NOT ClosedLoop AI. "Composable, fail-closed agent workflow blocks for TypeScript" by
    github.com/Yash456k -- an unrelated project that happens to share the word.
- name: github.com/closedloop-ai
  reason: >-
    NOT this company. That GitHub org is Closedloop.ai of Austin, TX (blog closedloop.ai), a
    different company. This provider's GitHub account is github.com/closed-loop-ai, with dashes,
    whose profile blog is https://closedloop.sh.
official_sdk_count: 0
official_sdk_note: >-
  Zero client SDKs for the REST API. The two npm packages are a CLI and an MCP client, not
  language bindings for /v1.
