Every response carries a status. `supported` means the Record answered. `partial`, `stale`, `under_review`, `ambiguous` and `unsupported` are all real answers about the Record and none of them is a fact about the product: report them as what FormulaSignal holds, never as what is true of the product. Read `limitations` and repeat what applies. An observation date is when a source was read, not when a change was made, and an observation window is not an exact reformulation date. Nothing here is medical advice or a suitability judgement for any person.","annotations":{"title":"Unwatch product","readOnlyHint":false,"openWorldHint":false,"idempotentHint":true,"destructiveHint":true},"source":"probe","observed_at":"2026-10-19T06:42:17.034Z"}],"dev.protogrid/trust":{"score":79,"components":{"hygiene":80,"liveness":99,"freshness":85,"provenance":55},"drivers":["+dns-namespace","+website","+reachable","+uptime-97%","~updated-52d-ago","-no-repository"],"flags":["no-repository"],"blocked":false,"computed_at":"2026-10-19T11:41:18.334Z","disclaimer":"Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed."},"dev.protogrid/quality":{"score":77,"label":"good","components":{"auth":null,"hygiene":79,"protocol":75,"stability":75,"dependencies":null},"checks":[{"id":"protocol.modern","detail":"newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28","status":"warn","category":"protocol"},{"id":"protocol.stateless","detail":"only applies to 2026-07-28 servers","status":"na","category":"protocol"},{"id":"protocol.transport","detail":"streamable HTTP","status":"pass","category":"protocol"},{"id":"protocol.list_ttl","detail":"only applies to 2026-07-28 servers","status":"na","category":"protocol"},{"id":"auth.prm","detail":"no remote uses OAuth","status":"na","category":"auth"},{"id":"auth.as_metadata","detail":"no remote uses OAuth","status":"na","category":"auth"},{"id":"auth.cimd","detail":"no remote uses OAuth","status":"na","category":"auth"},{"id":"auth.secret_in_url","detail":"no templated URL","status":"na","category":"auth"},{"id":"tools.descriptions","detail":"every tool has a description","status":"pass","category":"hygiene"},{"id":"tools.description_length","detail":"18 tools have descriptions over 1,024 characters, which crowds the context","status":"warn","category":"hygiene"},{"id":"tools.schemas","detail":"every tool has an object input schema","status":"pass","category":"hygiene"},{"id":"tools.annotations","detail":"18 of 18 tools declare readOnlyHint or destructiveHint","status":"pass","category":"hygiene"},{"id":"tools.directory_hints","detail":"2 of 18 tools declare all four hints; missing: record.search (destructiveHint); products.resolve (destructiveHint); products.serving_economics (destructiveHint); …","status":"warn","category":"hygiene"},{"id":"tools.token_cost","detail":"about 9,051 tokens to load every tool","status":"warn","category":"hygiene"},{"id":"tools.api_dump","detail":"tools are not a one-to-one API dump","status":"pass","category":"hygiene"},{"id":"stability.changes","detail":"36 tool changes in 30 days","status":"warn","category":"stability"},{"id":"stability.rug_pull","detail":"no tool changed its meaning under the same name","status":"pass","category":"stability"},{"id":"deps.known_vulns","detail":"no npm or PyPI package","status":"na","category":"dependencies"},{"id":"deps.mcp_sdk_version","detail":"no npm or PyPI package","status":"na","category":"dependencies"},{"id":"deps.resolvable","detail":"no npm or PyPI package","status":"na","category":"dependencies"}],"drivers":["~protocol.modern","~tools.description_length","~tools.directory_hints","~tools.token_cost","~stability.changes"],"flags":[],"tool_count":18,"token_estimate":9051,"tools_hash":"f8de4e3867ffb9188e29083655365ee2","tools_changed_at":"2026-09-27T06:32:12.986Z","computed_at":"2026-10-19T12:00:19.663Z","disclaimer":"Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed."},"dev.protogrid/identity":{"canonical_id":"com.formulasignal/record","aliases":[],"alias_count":0,"repository_key":null,"owner":{"verified":false,"method":null,"since":null}}},"next_actions":[{"action":"list_tools","description":"Every current tool with input schemas","href":"/v1/servers/com.formulasignal%2Frecord/tools","arguments":{"name":"com.formulasignal/record"}},{"action":"get_connection","description":"Minimal connection block for the preferred remote or package","href":"/v1/servers/com.formulasignal%2Frecord/connection?target=mcpServers","arguments":{"name":"com.formulasignal/record","target":"mcpServers"}},{"action":"search","description":"Find other servers by intent","href":"/v1/search?q={query}","arguments":{"q":"{query}"}}]}
