NAME COLLISION INSIDE ONE VENDOR, worth recording because it will catch an automated verifier: https://docs.stackone.com/mcp is also a live MCP server, but it is a Mintlify documentation server whose tools are search_stackone and query_docs_filesystem_stackone over StackOne's own docs, and it is read-only and scoped to published site content. It is not the unified-API server and must not be recorded as the product endpoint. The vendor's positioning line is a direct swipe at this directory's own subject matter and is quotable: \"First-party MCPs weren't built for production. StackOne's are.\" GTM connectors the research surfaced on StackOne include Salesloft, JustCall, Dialpad, Help Scout, RingCentral and Aircall, which means several vendors in this directory can be reached either directly or through StackOne, and a buyer should compare rather than assume the wrapper is worse. Vendor also advertises automated creation of new MCP servers, which would make the 518 figure a moving number. 2026-09-07: Official MCP registry carries com.stackone/mcp (DNS-verified stackone.com namespace) with remote https://mcp.stackone.com/mcp; that URL returned 401 to an MCP initialize, as did https://api.stackone.com/mcp (https://mcp.stackone.com/mcp). 2026-09-09 (P6-04 repo sweep): first-party repository recorded at https://github.com/StackOneHQ/stackone-plugin, the org StackOneHQ (profile site stackone.com), homepage docs.stackone.com, last push 2026-08-22. It is NOT the server source: the README says the plugin connects an agent to StackOne's HOSTED MCP server.
