Claude Code: ask. ### `aimrank_create_share_card` - The name "aimrank_create_share_card" says "create": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_healthcheck` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text iCOMPLY contract: liveness + DB-connectivity probe. ``` ### `aimrank_predict` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_predict_matchup_winner` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Predict the winner of a matchup BEFORE a vote is cast. Uses Glicko-2 win probability under the same formula matchmaking uses internally. Pairs with aimrank_submit_vote for the "Claude predicts, you vote, we compare" demo. Does not record a vote — read-only. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused. ``` ## Only reads (17) Looks things up and changes nothing. Claude Code: allow. ### `aimrank_discover_public_rankings` - The description's first verb is "browse": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_explain` - The name "aimrank_explain" says "explain": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_find_similar_domains` - The name "aimrank_find_similar_domains" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_get_agreement` - The name "aimrank_get_agreement" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Inter-annotator agreement — Layer 5. 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. ``` ### `aimrank_get_ceiling` - The name "aimrank_get_ceiling" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Pairwise-κ ceiling from qualification attempts. The upper bound any judge / RM can credibly hit on this domain — used to pin the L3 pilot refund clause (refund if κ < ceiling - 5pp). api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused. ``` ### `aimrank_get_crowd_bt` - The name "aimrank_get_crowd_bt" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_get_daily_pair` - The name "aimrank_get_daily_pair" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_get_data_card` - The name "aimrank_get_data_card" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Auto data card — Layer 7. Provenance + IAA + coverage + per-annotator quality + transitivity + qualification stats in one synthesized markdown audit artefact. Format: 'markdown' (default) or 'json' for structured summary. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused. ``` ### `aimrank_get_domain` - The name "aimrank_get_domain" says "get": a word for reading.

Description, as the server wrote it: ```untrusted-server-text Get the next pair of entities to evaluate. Strategies: adaptive (default), swiss, balanced, random, uncertainty, explore, information_gain. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused. ``` ### `aimrank_get_plackett_luce` - The name "aimrank_get_plackett_luce" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_get_ranking` - The name "aimrank_get_ranking" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch a ranking's metadata + top 25 entities sorted by rating. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused. ``` ### `aimrank_list_competitions` - The name "aimrank_list_competitions" says "list": a word for reading.

Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `aimrank_search_entities` - The name "aimrank_search_entities" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text Find entities by name substring within a ranking. api_key is optional on the public endpoint; on /mcp/mcp a missing key is refused. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `aimrank`: ```json { "permissions": { "allow": [ "mcp__aimrank__aimrank_get_daily_pair", "mcp__aimrank__aimrank_get_ranking", "mcp__aimrank__aimrank_get_leaderboard", "mcp__aimrank__aimrank_get_matchup", "mcp__aimrank__aimrank_search_entities", "mcp__aimrank__aimrank_discover_public_rankings", "mcp__aimrank__aimrank_list_domain_entities", "mcp__aimrank__aimrank_get_domain", "mcp__aimrank__aimrank_list_competitions", "mcp__aimrank__aimrank_get_data_card", "mcp__aimrank__aimrank_get_agreement", "mcp__aimrank__aimrank_get_ceiling", "mcp__aimrank__aimrank_get_plackett_luce", "mcp__aimrank__aimrank_get_crowd_bt", "mcp__aimrank__aimrank_list_public_judges", "mcp__aimrank__aimrank_find_similar_domains", "mcp__aimrank__aimrank_explain" ], "ask": [ "mcp__aimrank__aimrank_create_share_card", "mcp__aimrank__aimrank_predict_matchup_winner", "mcp__aimrank__aimrank_predict", "mcp__aimrank__aimrank_healthcheck" ], "deny": [] } } ```
