note: 'HackNotice publishes no conventional REST client SDK in any language. What it does publish
  is two first-party n8n community nodes, released from its own GitHub organization via GitHub
  Actions and authored under nicolas@hacknotice.com with url https://hacknotice.com — one wrapping
  the REST API, one acting as an MCP client for the hosted MCP server. Registries with no HackNotice
  package at all: PyPI (404), RubyGems (404), crates.io (no crate), Maven Central, NuGet, pkg.go.dev.'

  covers: REST API — alerts, watchlists, saved searches, assessments, research, leak-file search
  note: 'Fetch HackNotice alerts and saved searches from n8n workflows (REST API). Supports both
    auth flows: apiKey + email + password, and X-HackNotice-Integration-Key. Declares the production

  kind: mcp-client-node
  covers: All hacknotice-mcp-server tools, discovered live via MCP tools/list
  note: 'MCP client for n8n, not an MCP server: it POSTs JSON-RPC 2.0 over Streamable HTTP to the
    fixed endpoint https://mcp.hacknotice.com:13330/mcp and exposes every discovered tool to an
    n8n AI Agent. Deliberately avoids @modelcontextprotocol/sdk (ESM) and implements the client
    half of the transport itself.'

  note: 'Reserved then UNPUBLISHED — registry.npmjs.org returns the package document with an
    "unpublished" time key, no dist-tags and no description. Superseded by n8n-nodes-hacknotice-api.
    Recorded so a consumer following an old reference knows why it resolves to nothing.'
