So the keyless surface is advertised to a stranger as documented and has been stable across four server versions since 2026-09-09. This record measures the listing only; whether a listed tool can be called keyless is measured in the companion record p-20261009-firecrawl-mcp-keyless-tool-call of the same minute, and on this date it could not. Listing a tool is not calling it.",
