description: 'Anthropic is an AI safety company and the creator of the Claude family of large language models (Opus, Sonnet,
  Haiku, and the Fable/Mythos frontier line). The Claude Developer Platform exposes them through a single REST API at api.anthropic.com:
  the Messages API for text, vision, tool use, thinking, streaming and structured outputs; Message Batches for asynchronous
  work at half price; Files, Token Counting, Models, and experimental Prompt Tools; Managed Agents with sessions, environments,
  memory stores, vaults and scheduled deployments; a Skills API; and an Admin API for organizations, workspaces, members,
  invites and API keys. Authentication is x-api-key with a required anthropic-version date header and dated anthropic-beta
  opt-ins. Anthropic also authors two of the open standards the agent ecosystem runs on — the Model Context Protocol and the
  Agent Skills specification — and ships Claude Code, the terminal agentic coding tool, which doubles as a first-party stdio
  MCP server.'

    from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server
    correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
