RECLASSIFIED FROM THE CANDIDATE ROW for the same reason as Pipeworx: the research filed it "third-party wrapper (community)", which describes its relationship to the wrapped vendors correctly, but the servers are usefulapi's own first-party product, so mcp_status is official with the qualifier carried in the value itself. THE CAVEAT IS THE ENTRY: none of the wrapped vendors endorses these servers, the wrapped vendor's own terms of service still govern the API calls underneath, and connecting one means a third party sits in the OAuth path to a system of record. GTM-relevant servers seen in the catalogue include Aircall (27 tools), Pipedrive, Mixpanel, Chargebee, Zendesk and Groove HQ. The Aircall server page is a good worked example of the transparency: every tool names its upstream call, for instance aircall_search_calls documented as "Aircall REST: GET /calls/search". Compare against 02-engagement-outbound.md's Aircall entry, where the only servers found were community ones, and note that this host is one of them. 2026-09-07: The repo is the usefulapi portal and server catalogue: README "usefulapi - Hosted MCP servers for the tools you already use ...
