  Membrane (formerly Integration.app) publishes its client libraries on npm only. The company
  rebranded in 2025 and moved its packages from the @integration-app scope to @membranehq; both
  scopes are recorded here because the legacy scope is still installable and is the abandonment
  signal for anyone still pinned to it. No PyPI, RubyGems, Maven, NuGet, crates.io or Go module
  was found under either name; the docs SDK page lists TypeScript/JavaScript, React, Vue (via the
  React adapter) and the CLI and nothing else.

    Pre-rebrand React SDK. Its own npm description now reads "Package has moved to
    @membranehq/react", which is the provider stating the move itself.
  superseded_by: '@membranehq/react'
not_found:
  note: >-
    Probed and absent, recorded so a later run does not re-litigate them. Each returned a registry
    404 / "Not found" on 2026-09-13.
  packages:
  - name: integration-app-mcp-server
    registry: npm
    version: null
    note: >-
      The name declared in package.json of github.com/membranehq/mcp-server (v1.3.0), but the package
      is not published to npm. The self-hosted MCP server is distributed as a git clone + Docker
      build only, which is why mcp/ records no npx install line.
  - name: '@membranehq/agent-skills'
    registry: npm
    version: null
    note: >-
      The Agent Skills are distributed through `npx skills add membranehq/agent-skills`, which reads
      the GitHub repo directly; there is no npm package behind that command.
  - name: '@membranehq/vue'
    registry: npm
    version: null
    note: The Vue.js guide wraps @membranehq/react; no dedicated Vue package exists.
