TrackDIFF does not always answer
Over the last week it answered 90.8% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

If a tool disappears, we record the date.
champion
get_champion_build
The build TrackDIFF shows for a champion in its main role: starting items (+ trinket), the highest-win-rate core three-item builds, situational items, full build paths, skill max orders and level-by-level skill points, summoner spells, rune pages with stat shards, and final-item presence — each with games and win rate (0–1). Items, runes and spells are Data Dragon numeric ids. `patch` is the patch the numbers come from (TrackDIFF falls back one patch when the newest has too few games unless you pin `patch`). `null` means no build data for that champion/patch yet.
get_champion_stats
Without `champion`: the current-patch champion board (top `limit` rows by TrackDIFF's tier grade): rank, champion, games, win rate, pick rate, ban rate (all 0–1), tier grade (S+…D), roles played and worst matchups, optionally for one role and one rank bucket. With `champion`: that champion's headline stats, per-role split, and its board standing, pinnable to a `patch` like "16.17". Stats are ranked solo/duo from the games TrackDIFF tracks. For items/runes/skill order call `get_champion_build`.
player
get_player_live_game
Whether an account is in a ranked game right now and, if so, the lobby TrackDIFF shows on its Live Game tab: `gameId`, `startedAtMs`, bans, and all ten participants with champion, team, summoner spells, keystone, current rank/LP, primary role, their win rate on the champion they are playing (0–1), and public persona. `in_game: false` means no game is in progress (or the account is not indexed). Data comes from TrackDIFF's own live-game tracker and may lag a game start by a minute or two.
get_player_profile
One League of Legends account by Riot ID: identity (Riot ID, level, primary role, linked public persona), current ranked solo/duo standing with wins/losses, this split's peak, apex ladder rank (null below Master), the most-played champions with win rate/KDA/CS per minute, and recent form summarised from the last 20 solo games (wins, losses, win rate, average K/D/A). `indexed: false` means TrackDIFF has not seen this account; no data is fetched on demand. Win rates are 0–1 fractions; timestamps are Unix ms. For the game they are in right now use `get_player_live_game`.
event
get_event_standings
One public event by slug: its summary (name, kind, status, dates) and the standings board — each member's rank, Riot ID, region, current tier/division/LP, persona and team tag, done/failed flags, and the kind-specific `progress` payload (LP gained for a race, challenge counters, …). `peak: true` shows the board as a record (best standings, hidden members re-admitted) instead of live. Unknown slug → an error; find slugs with `list_events` or `search`.
events
list_events
TrackDIFF's public events — ranked races, team events, champion challenges — as hub cards: slug, name, description, kind, lifecycle status (scheduled/active/ended/…), start/end dates, roster size and the regions the roster plays on. Filter by `status`, `featured` (the curated hub) or `kind`. Call `get_event_standings` with a card's `slug` for its leaderboard.
leaderboard
get_leaderboard
One page (100 rows) of a region's Master+ ranked solo/duo ladder as TrackDIFF shows it: rank, Riot ID (summonerName#tagLine), tier/division/LP, wins/losses, LP change over `span`, whether the player is live-streaming or in a game, and their public persona (streamer/pro) if any. `board: "prestige"` is the global Master+ board filtered to ≥69% win rate and ignores `region`. Use `get_rank_cutoffs` for the Challenger/Grandmaster thresholds and `get_player_profile` for one player. Pages beyond 10 are not served — this is an answer, not a dataset.
live
list_live_streamers
League of Legends streamers live right now that TrackDIFF tracks, as cards: display name, platform and channel, stream title, viewer count, the champion they are playing (`liveChampionId`), their best account's rank, primary role, region and top champions. Filter by champion, role, tier or region; 24 cards per page. Empty rows mean nobody matching is live. For one streamer's full page call `get_persona`.
persona
get_persona
A public TrackDIFF persona (a streamer or pro player) by site slug or display name: their linked Riot accounts with region, current tier/division/LP and whether they played recently, live status per platform (Twitch/Kick/SOOP) with stream title and start time, social links, esports team, best champion-board standing, and recent clips. Only accounts the owner made public are listed. `found: false` means no persona matches — try `search` with the name. For one account's ranked detail call `get_player_profile` with its Riot ID.
rank
get_rank_cutoffs
A region's apex cutoffs right now: the LP needed for Challenger and for Grandmaster (`challengerCutoff`, `grandmasterCutoff`), how many players hold each apex tier, how much each cutoff moved since the region's midnight (`*DeltaToday`, null when unknown), when the ladder snapshot ran (`updatedAtMs`), and the primary-role mix of the top 200. Cutoffs are positional (Riot's apex slots), not a formula.
search
search
The site's typeahead over everything TrackDIFF indexes: players (whole ladder, typo-tolerant; each with region, tier/division/LP, persona and whether they are in a game), personas (streamers/pros, with live status), champions (name and slug) and events. Use it to turn a half-remembered name into a Riot ID, persona slug, champion slug or event slug for the other tools. `resolveHint` is set when the query is already an exact "Name#TAG". `source: "fallback"` means the full-ladder index was unavailable and players are apex-only.

TrackDIFF — questions
Answers built from our own checks of this server.
What can TrackDIFF do?
It exposes 11 tools, read directly from the server on our last check. Among them: get_champion_build, get_champion_stats, get_event_standings, get_leaderboard, get_persona, get_player_live_game and 5 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 →
What is TrackDIFF mostly used for?
Its tools cluster around player and champion. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is TrackDIFF 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 502 ms. The bar chart above shows every period we have measured.
How do I connect TrackDIFF?
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 TrackDIFF need an API key?
No. TrackDIFF completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is TrackDIFF?
It answers our handshake in 502 ms on average, which is faster than 24% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
