source: openapi/ (23 operations across the two published Gravity Connect OpenAPI documents)
note: 'Virtual Peaker publishes NO MCP server. Searched the docs, the two Gravity Connect Redoc references,
  the marketing site, virtual-peaker.com/llms.txt, the github.com/virtual-peaker org, npm (@modelcontextprotocol
  and vendor scopes) and the public MCP registries — nothing. This is a CANDIDATE tool surface derived
  one-tool-per-operation from the provider''s own OpenAPI so the API is representable to agents; it is
  not a provider claim and nothing is hosted. Each tool inherits its real input schema from the backing
  operation''s parameters + requestBody in the referenced spec. Note the asymmetry of Gravity Connect:
  the device-partner half is implemented by the OEM (servers[] is the placeholder https://example.com),
  so those tools have no single canonical host; only the VPP publishing half resolves to https://partner.virtualpeaker.io/v1.'
