  EventRegistry GitHub organization (https://github.com/orgs/EventRegistry/repos) and the
  SDK pointers already recorded in apis.yml.

  First-party client libraries and the first-party MCP server published by Event Registry
  (NewsAPI.ai). Every version/published pair below was read from the registry metadata
  endpoint on 2026-08-13.

    note: >
      Official Python SDK, 260 GitHub stars. Registry metadata reports the latest release as
      9.1 on 2023-06-23; the GitHub repository was last pushed 2023-06-23. The SDK has not
      been republished in the three years since, while the API itself has continued to add
      parameters (the first-party MCP server released `conceptOper`, `categoryOper`,
      `dateMentionStart/End` and expanded `articlesSortBy` values during 2026) — a currency
      gap a consumer should account for.

      First-party Model Context Protocol server, published by the EventRegistry GitHub
      organization and linked as the package homepage on the repo. This is the most current
      first-party client Event Registry ships and it is the one tracking the live API surface
      — it carries a dated CHANGELOG.md and exposes 8 MCP tools (verified by a local
      tools/list probe on 2026-08-13). See mcp/event-registry-mcp.yml.

  The two general-purpose SDKs (Python 2023-06-23, Node 2024-11-14) are materially older than
  the MCP server (2026-03-18). Event Registry's investment has visibly moved from SDKs to the
  agent surface.
