  Tool names and categories captured verbatim from Harmonic's published llms.txt (MCP Server Tools
  section). The provider states 40+ tools; the ~23 named above plus their net-new/people-list variants
  make up the published surface. Unofficial third-party servers (e.g. blue-yard/harmonic-mcp-server)
  exist on GitHub but are distinct from this official hosted server.
