The only first-party code is a GitHub repo holding zero-dependency Node and Python reference clients for the MCP server, plus a server.json. None of these is an SDK, so no SDKs pointer is emitted.' registries_probed: - registry: npm queries: - numbers-online - '@numbers-online/sdk' - numbersonline - numbers-online-mcp - '@numbers-online/mcp' - search?text=numbers-online result: 404 on every name; search returns unrelated packages - registry: pypi queries: - numbers-online - numbersonline - numbers_online result: 404 on every name - registry: github queries: - orgs/numbers-online - search/repositories?q="numbers.online" result: 'org exists (created 2026-06-16, contact@numbers.online, blog https://numbers.online) with one repo: numbers-online/numbers-online-mcp (MIT, pushed 2026-06-16, no releases, no package manifest)' packages: - language: javascript registry: github kind: reference-client name: numbers-online-mcp/examples/node/lookup.mjs url: https://github.com/numbers-online/numbers-online-mcp/blob/main/examples/node/lookup.mjs install: none — a single-file script run with node 18+ (NUMBERS_ONLINE_KEY=… node lookup.mjs +14155552671) official: true version: null published: null note: 'Not on a registry and not versioned: a zero-dependency fetch-based example that speaks the Streamable HTTP transport.
