Nothing serious here today
Today is the operative word: we check Attic every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

attic
attic_card_sold_comps
STUB. Does not return eBay sold prices for sports cards. Do not call this to price a card, and do not invent a hammer or a sold comp. Requires an Attic API key. PCGS is unrelated and is not offered.
attic_coin_sold_comps
STUB. Does not return sold prices for coins. Do not call this to price a coin, and do not invent a hammer. Requires an Attic API key. PCGS comps are not offered.
attic_comps_status
Whether PSA cert lookup and the eBay-sold bridge are configured or live. No upstream price call. PCGS comps are not offered. If live is false, do not quote sold prices or grades. Public.
attic_get_article
Get one atticcapital.com article by WordPress slug: title, date, excerpt, markets, dossier slugs, and episode numbers. The excerpt is a summary of at most 400 characters. Do not fetch the article HTML.
attic_get_changes
Ledger of roster and gathering moves since the prior weekly cut. Use this for 'what changed', rank moves, names that entered or left a top 5. Optional since (YYYY-MM-DD), market, and layer. layer=beyond is Attic Beyond. An empty list means the rosters did not move.
attic_get_dossier
Get an Attic object dossier by market and slug: thesis, risk flags, related Creators episodes, and outbound links. About 38 Creators-grounded briefs. Slugs appear on articles and episodes. Attic Beyond: needs an API key. Unknown slugs 404. Do not invent a dossier.
attic_get_episode
Get one Creators episode by episode number or slug. Prefer episode when you have the number. Returns the summary, show notes on atticcapital.com, collection, and audio URL. Public.
attic_get_indexes
Attic Market Strength composites for rare coins, sports cards, collector cars, and fine art. Week-0 levels are 100 until scored inputs exist. Peer feeds may be stub_until_licensed. Omit market for the full package. Attic Beyond: needs an API key. Do not invent index levels. This is not the Price Indexes pillar of the weekly report.
attic_get_market_report
Get one weekly top-5 roster for a market, layer, and pillar. Use this for 'top 5', 'who is in the report', or a Headlines / Beyond pillar. For the paragraph on one rank, call attic_get_report_entry. For a name across pillars, use attic_search. layer=beyond is Attic Beyond and needs an API key.
attic_get_report_entry
Get one ranked name from a weekly pillar pack, with its summary and a short expanded excerpt. Requires market, layer, and pillar. rank is 1-5 and defaults to 1. The excerpt is not the whole page. layer=beyond is Attic Beyond.
attic_list_articles
List published atticcapital.com articles: title, date, URL, and a short excerpt. Never the full body. Optional q matches title, slug, and excerpt. Optional market (rare-coins, sports-cards, collector-cars, art, or other) and since (YYYY-MM-DD). Newest first.
attic_list_episodes
List Creators & Cultural Icons podcast episodes (public): number, title, date, summary, show-notes URL, and audio URL. Optional q searches title, slug, and summary. Optional market filters the mapped collection. Newest episode number first.
attic_list_gatherings
List shows, auctions, and other gatherings on the Attic calendar. Optional market filter. Public. This is the calendar, not the Gatherings pillar of the weekly report (use attic_get_market_report with pillar gatherings for that top 5).
attic_list_markets
List the four Attic collector markets (rare coins, sports cards, collector cars, fine art) with Headlines, Beyond, and Creators page URLs on atticcapital.com. Use this when you need the canonical page to link, not a top-5 roster.
attic_list_pillars
List the 14 locked report pillars in order (Collectors through Insights In Depth). Use the slug with attic_get_market_report. This does not return the ranked names.
attic_lookup_psa_cert
STUB. Does not return a PSA grade or population. PCGS comps are not offered. Do not call this to answer what a card graded or sold for. Requires an Attic API key; without one, the tool explains Attic Beyond. Never invent a cert result.
attic_search
Keyword search across roster names, summaries, and expanded report copy. The parameter is query (not q). This does not search articles or episodes. Optional market and layer filters. layer=beyond is Attic Beyond. Use attic_list_articles for the article archive.
attic_status
Current Attic connector status: API version, the weekly as-of date, the four markets, and the 14 pillars. Call this first when the user asks what week the reports cover.

Attic — questions
Answers built from our own checks of this server.
What can Attic do?
It exposes 18 tools, read directly from the server on our last check. Among them: attic_card_sold_comps, attic_coin_sold_comps, attic_comps_status, attic_get_article, attic_get_changes, attic_get_dossier and 12 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Attic working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 295 ms. The bar chart above shows every period we have measured.
How do I connect Attic?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Attic need an API key?
No. Attic completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 18 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Attic?
It answers our handshake in 295 ms on average, which is faster than 55% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Attic?
The npm package attic-mcp was installed 26 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
