Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security66
  • The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
  • Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
  • HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
  • The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
  • DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
Schema Quality & AI Usability64
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 915 tokens (~228/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability check failed: schema churn in the 8 days we've observed: 0 tool removals, 4 breaking changes, 0 auth/transport breaks, 0 additions. See how to fix → Fail
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 4 exposed · ~810 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
hn_get_stories ~123

Fetch stories from an HN feed (top, new, best, ask, show, jobs), with title, URL, score, author, and comment count for each story.

NameTypeReqDescription
countintegerNumber of stories to return. Larger counts take longer.
feedstringyesWhich HN feed to fetch. "top" includes jobs. "ask" and "show" are Ask HN / Show HN posts.
offsetintegerNumber of stories to skip from the start of the feed. Use with count for pagination.
NameTypeReqDescription
capnumberThe count cap that was applied.
feedstringyesWhich feed was fetched.
hasMorebooleanyesWhether more stories are available beyond this page.
noticestringRecovery hint when a page is empty — e.g. offset past end of feed or feed has no items. Absent on non-empty result pages.
offsetnumberyesOffset that was applied to this page.
shownnumberNumber of stories returned on this page.
storiesarrayyesStories from the feed, ordered by HN ranking.
totalnumberyesTotal items in the feed (up to 500 for top/new/best, 200 for ask/show/jobs).
truncatedbooleanTrue when the feed was capped by the count parameter.

No examples provided.

hn_get_thread ~165

Get an item and its comment tree as a threaded discussion, with child comments resolved recursively. Use depth 0 for an item-only lookup.

NameTypeReqDescription
depthintegerHow many levels of replies to resolve. 0 = just the item, no comments. 1 = direct replies only. Popular stories often have more top-level comments than maxComments — to see nesting, raise maxComments…
itemIdintegeryesID of the story, comment, or poll to fetch the thread for.
maxCommentsintegerMaximum total comments to include across all depth levels. Highest-ranked top-level comments resolve first; replies fill in only after the level above is exhausted.
NameTypeReqDescription
capnumberThe maxComments cap that was applied.
commentsarrayyesFlat comment list ordered breadth-first by rank: highest-ranked top-level comments first, then their replies. Use depth/parentId to reconstruct nesting.
itemobjectyesThe root item (story, comment, or poll).
noticestringTruncation context: counts of deleted/dead comments dropped during traversal, or pagination hint when totalLoaded < totalAvailable. Absent when no comments were dropped and all available comments wer…
shownnumberNumber of comments returned.
totalAvailablenumberTotal comment count from the root item. If totalLoaded < totalAvailable, raise maxComments (and depth, if you want nested replies) and call again.
totalLoadednumberyesNumber of comments actually fetched and included.
truncatedbooleanTrue when the comment list was capped by maxComments.

No examples provided.

hn_get_user ~184

Get an HN user profile with karma, about, and optionally their most recent submissions resolved into full items.

NameTypeReqDescription
includeSubmissionsbooleanResolve the user's most recent submissions into full items. Without this, only the submission count is available.
submissionCountintegerPage size — how many submissions to resolve per call. Only used when includeSubmissions is true.
submissionOffsetintegerHow many submissions to skip before resolving, counting back from the most recent. Use with submissionCount to page through a long history: request offset 0, then offset submissionCount, and so on. T…
usernamestringyesHN username. Case-sensitive. Trimmed; blank or whitespace-only input is rejected.
NameTypeReqDescription
capnumberThe submissionCount cap that was applied.
noticestringPagination context — which window of the history this page covers and the submissionOffset to send next, or a warning that the offset is past the end. Absent when the page reaches the end of the hist…
shownnumberNumber of submissions returned.
submissionOffsetnumberThe offset this page started at. Absent when includeSubmissions is false or the user has never submitted.
submissionsarrayOne page of submissions, most recent first, starting at submissionOffset. Absent when includeSubmissions is false or the user has never submitted. Empty when the page holds no live items — either the…
truncatedbooleanTrue when submissions remain beyond this page.
userobjectyesUser profile.

No examples provided.

hn_search_content ~338

Search Hacker News stories and comments via Algolia. Filterable by content type, author, date range, and minimum points.

NameTypeReqDescription
authorstringFilter results to a specific author. Useful for finding a user's posts on a topic (hn_get_user only shows recent submissions). Trimmed before filtering; omit the field to search all authors rather th…
countintegerNumber of results to return.
dateRangeobjectFilter to a date window. Useful for finding discussions about recent events.
minPointsintegerMinimum score/points. Filters out low-engagement content.
pageintegerPage number for pagination (0-indexed).
querystringyesSearch terms. Supports simple keywords — Algolia handles stemming and relevance. Trimmed before searching; blank or whitespace-only input is rejected.
sortstringSort order. "relevance" for best match, "date" for most recent first.
tagsstringFilter results by content type. Omit to search all types.
viewstringHow much of each hit to return. "full" includes every field. "compact" omits the two body-text fields — `text` and `highlights.text` — which together can repeat a long comment twice per hit; everythi…
NameTypeReqDescription
capnumberThe count cap that was applied.
hitsarrayyesSearch results ranked by sort order.
noticestringRecovery hint when results are empty — names the filters applied, for relaxing the search. Absent on non-empty result pages.
pagenumberyesCurrent page number (0-indexed).
querystringyesThe query that was searched.
shownnumberNumber of hits returned.
totalHitsnumberyesTotal matching results across all pages.
totalPagesnumberyesNumber of pages Algolia will actually serve for this query. Not derived from totalHits — broad queries report a totalHits far larger than the reachable page range, so paginate against this value.
truncatedbooleanTrue when the hit list was capped by the count parameter.
