AimRank turns pairwise judgements -- this one is better than that one -- into calibrated rankings and RLHF-ready preference data, with an audit-citeable data card. Ratings come from one of 6 rating engines (Glicko-2 default, Elo, Bradley-Terry, TrueSkill, OpenSkill, Elo-MMR), never a vote tally; Plackett-Luce and CrowdBT are 2 offline audit aggregators that never write ratings. The quality evidence is real: Fleiss kappa / Scott's pi / Krippendorff alpha (Cohen's kappa only where there are exactly 2 raters), Wilson 95% intervals, calibration, drift, and a complementarity metric measuring…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
aimrank_list_public_judges reads open 24h ago
Browse public judge-prompt artifacts shared by other users. Filter by ``category`` (free-text), ``domain_id``, or both. Sort options: ``fork_count`` (default — most-forked first), ``recent``, ``faithfulness``. Returns artifact summaries WITHOUT the full prompt text — call `aimrank_fork_judge_prompt` or the REST GET to retrieve the full prompt before using it. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

iCOMPLY contract: liveness + DB-connectivity probe.
{ "type": "object", "title": "icomply_healthcheckArguments", "properties": {} }arguments 5 linesaimrank_get_daily_pair reads open 12h ago
Fetch today's Daily Pair — the trending matchup chosen at 00:00 UTC. Pairs with the `vote_of_the_day` agent template. Returns the challenge + a fresh matchup. If the cron hasn't run yet, falls back via ok=False so the agent can use `aimrank_get_matchup` instead. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Browse public rankings — agent equivalent of surfing aimrank.io. Filters: category, media_type ("text" | "image" | "audio" | "video"), sort ("trending" | "recent" | "most_votes" | "random"), limit 1-50. Each result embeds share assets so the agent can hand any ranking back to the user as a clickable link without a follow-up call. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Get the next pair of entities to evaluate. Strategies: adaptive (default), swiss, balanced, random, uncertainty, explore, information_gain -- the same selection the web app uses. Left/right order is randomised, and the pair comes with no rating or predicted winner (match_quality is closeness only), so show it to the voter as-is. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Predict a matchup's winner from the current ratings -- for analysis. Uses Glicko-2 win probability under the same formula matchmaking uses internally. Use it to analyse a ranking, or AFTER a vote to compare the cast vote with what the ratings expected. Never show a prediction to a voter before they vote: a voter who sees who "should" win anchors on it, and the preference data stops being independent. Does not record a vote — read-only. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Get domain details including entity pool and competition list. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.
{ "type": "object", "title": "get_domainArguments", "required": [ "domain_id" ], "properties": { "api_key": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Api Key", "default": null }, "domain_id": { "type": "string", "title": "Domain Id" } } }arguments 25 linesaimrank_get_leaderboard reads unknown 3h ago
Get the top N entities of a ranking with honest uncertainty. Ratings come from a Bradley-Terry fit over the counted votes, each with a 95% interval (ci_95). `rank` is tie-aware — entities the data cannot separate share a rank — and `provisional` is true while any do. `method` says how the numbers were computed. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.
{ "type": "object", "title": "get_leaderboardArguments", "required": [ "ranking_id" ], "properties": { "limit": { "type": "integer", "title": "Limit", "default": 10 }, "api_key": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Api Key", "default": null }, "ranking_id": { "type": "string", "title": "Ranking Id" } } }arguments 30 linesaimrank_get_ranking reads unknown 19h ago
Fetch a ranking's metadata + its top 25 entities. Entities carry a Bradley-Terry rating with a 95% interval (ci_95) and a tie-aware rank: entities whose intervals overlap share a rank. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.
{ "type": "object", "title": "get_rankingArguments", "required": [ "ranking_id" ], "properties": { "api_key": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Api Key", "default": null }, "ranking_id": { "type": "string", "title": "Ranking Id" } } }arguments 25 linesaimrank_create_share_card reads unknown never probed
Return share-ready URLs + embed snippets for a ranking. Formats: "all" (default — everything), "twitter", "linkedin", "embed_leaderboard", "embed_vote", "badge_markdown", "qr_code", "data_card". Pass these to a human to paste into a tweet, blog, Notion page, or Slack message. The OG image renders automatically when the public_url is unfurled by Twitter / LinkedIn / Slack. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Inter-annotator agreement — Layer 4. Returns Cohen's κ (n=2 raters), Fleiss' κ, Krippendorff's α, Scott's π + Landis-Koch interpretation, plus the multi-rater coverage report. `min_raters` overrides the ranking's configured min_raters_per_pair. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Plackett-Luce listwise ranking aggregation — OFFLINE AUDIT ONLY. Reported post-hoc; it NEVER writes ratings, and setting it as a ranking's algorithm returns 400. AimRank has 6 rating engines plus 2 offline aggregators (this and CrowdBT) — never describe it as an 8th rating algorithm. Generalises Bradley-Terry to ranked lists. On pairwise data, collapses to BT MLE — useful as a second-opinion aggregator. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

Find public domains most similar to a query or a known domain. Use ``query`` for free-text search ("pharma evaluation") OR ``domain_id`` to find domains similar to one you already know. Exactly one must be provided. TF-IDF + cosine similarity over name + description + category + declared constitution + objectives text. Cheap (no embedding API calls), 5-minute in-process cache. Only public domains are searched / returned. Score in [0, 1] — typical "useful match" threshold is ≥0.15; "near duplicate" is ≥0.5. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

iCOMPLY contract: pairwise prediction with provenance fields. Returns the engine's predicted winner + probability shaped so iCOMPLY's Annex IV section-4 generator can ingest the response directly. See [iCOMPLY_INTEGRATION_STRATEGY.md] for the contract. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

iCOMPLY contract: explain a prediction in features + narrative. Returns the Glicko-2 μ/φ inputs for both entities + a deterministic narrative. No LLM-synthesised rationale — these are the actual numbers the math uses, which is exactly what an Annex IV auditor needs to trace. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.

CrowdBT — joint fit of entity scores + per-annotator reliability η. Surfaces noisy / anti-correlated raters explicitly. Methodology audit, not a live engine. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused.
{ "type": "object", "title": "get_crowd_btArguments", "required": [ "ranking_id" ], "properties": { "api_key": { "anyOf": [ { "type": "string" }, { "type": "null" } ], "title": "Api Key", "default": null }, "ranking_id": { "type": "string", "title": "Ranking Id" }, "max_iterations": { "type": "integer", "title": "Max Iterations", "default": 300 }, "min_votes_per_entity": { "type": "integer", "title": "Min Votes Per Entity", "default": 2 }, "min_votes_per_annotator": { "type": "integer", "title": "Min Votes Per Annotator", "default": 5 } } }arguments 40 linesaimrank_get_data_card reads unknown 6h ago
Auto data card — Layer 7. Provenance + IAA + coverage + per-annotator quality + transitivity + qualification stats in one synthesized markdown audit artefact.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id4b1752598b100101.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/4b1752598b100101/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
