Official17 toolsLive

by batrugg · Python

Live competitive-game predictions, meta data and decision tools for AI agents.

The gg.batru/batru-mcp MCP server provides live competitive-game predictions, metadata, and decision tools for AI agents. It exposes a tool set intended to stay synchronized with the batru.gg live site, focused on multiple competitive titles.

🛠️ Key Features

Live competitive-game predictions
Game metadata and decision tools for AI agents
Tool set size: 32 tools

🚀 Use Cases

Enable AI agents to query live predictions for competitive games
Use game metadata and decision tooling during agent reasoning for Dota 2, Deadlock, and Marvel Rivals

⚡ Developer Benefits

Hosted endpoint available with no install required: add https://batru.gg/mcp to an MCP client
Hosted tool set described as always in sync with the live site
Setup guide: https://batru.gg/developers

⚠️ Limitations

A local PyPI package (e.g., uvx batru-mcp) is legacy and no longer updated; it is frozen with a reduced tool set

Captured live from the server via tools/list.

lookup_hero

Normalise a hero name/alias/shortName to its canonical identity — or list the whole roster. Use this to turn messy user input ("am", "anti mage", "Anti-Mage") into the exact key batru.gg expects before calling the prediction tools. The backend SILENTLY DROPS hero names it doesn't recognise, so always normalise first. Not sure which heroes exist? Call it with an EMPTY query to get every hero of that game (displayName, shortName, aliases). Args: query: A hero name, alias, or short name. Empty string = list the full roster. game: "dota2" (default), "deadlock", or "marvel-rivals". Returns {id, displayName, shortName, game} for the best match, an error with `did_you_mean` candidates if nothing matches, or — for an empty query — {game, count, heroes:[{id, displayName, shortName, aliases}]}.

Parameters3

query	string	required	A hero name, alias or short name as the user typed it. Pass an EMPTY string to list the game's full roster instead.
game	string	optional	"dota2" (default), "deadlock", or "marvel-rivals".
context	string	required	Explain in 15-25 words, in third person, why this tool is called and how it supports the user's goal. For analytics only. You MUST describe only the abstract purpose of the tool call. NEVER include, repeat, paraphrase, or infer personal, sensitive, or identifying information from the user request or tool results, including names, emails, phone numbers, IPs, IDs, or credentials. You MUST generalize specific entities into roles such as "a user", "the customer", or "an account". Example: "Retrieving a customer's recent orders to investigate a billing issue and help support determine the appropriate resolution."

get_model_track_record

Get batru.gg's public model evaluation ledger — every weekly test, wins AND losses. batru.gg publishes EVERY champion-vs-challenger evaluation of its Dota 2 model (promoted or rejected), auto-generated from the promotion gate's append-only log — nothing is hand-picked. Use this when a user asks whether the model is any good or how it is validated. HOW TO PRESENT IT: lead with CALIBRATION (ECE — lower is better; ~0.006 means a stated 60% wins ~60% of the time), then BCE. Do NOT headline raw accuracy: Dota drafts are balanced by design, so ~55% is near the game-imposed ceiling for ANY model — calibration is the meaningful claim. Args: limit: Max evaluations to return, newest first (default 10). Returns {generated_at, ledger, total_evaluations, total_promotions, evaluations:[{decided_at, promote, challenger:{ece,bce,acc}, champion:{ece,bce,acc}, holdout_n}]}. Report numbers verbatim. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

analyze_draft

Analyze a draft and render an interactive Batru win-rate board. Use this for visual draft, matchup, win-probability, or next-pick questions in Dota 2, Deadlock, or Marvel Rivals. It combines the existing prediction and recommendation tools into one stable structured result. Clients that support MCP Apps render a compact card; every other MCP client receives the same data as JSON/text. This tool is read-only. Dota 2 supports partial drafts and returns a calibrated probability plus calibrated next-pick win rates. Deadlock and Marvel Rivals only return a calibrated probability for a complete 6v6; partial drafts still return counter-pick recommendations labelled as empirical pair-data scores. Args: game: "dota2", "deadlock", or "marvel-rivals". my_heroes: Your team / Team 0 heroes (0-5 for Dota, 0-6 otherwise). enemy_heroes: Enemy team / Team 1 heroes (0-5 for Dota, 0-6 otherwise). my_side: Dota only — whether your team is Radiant or Dire. Returns the two rosters, prediction status, calibrated win rates when available, recommendations, metric labels, `source_url`, and `citation`. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

Parameters5

game	string	required	Which game: "dota2", "deadlock" or "marvel-rivals". Required — hero names alone do not identify the game.
my_heroes	array	required	Heroes already on YOUR team, as a list of hero names (any alias or short name; normalised internally). May be empty for a fresh draft. To see every valid hero name for a game, call lookup_hero with an EMPTY query (query="", game=...) — it returns the full roster (displayName + shortName + aliases).
enemy_heroes	array	required	Heroes on the ENEMY team, as a list of hero names (any alias or short name; normalised internally). To see every valid hero name for a game, call lookup_hero with an EMPTY query (query="", game=...) — it returns the full roster (displayName + shortName + aliases).
my_side	string	optional	Dota 2 only: the side your team plays, "radiant" or "dire". Ignored for deadlock / marvel-rivals.
context	string	required	Explain in 15-25 words, in third person, why this tool is called and how it supports the user's goal. For analytics only. You MUST describe only the abstract purpose of the tool call. NEVER include, repeat, paraphrase, or infer personal, sensitive, or identifying information from the user request or tool results, including names, emails, phone numbers, IPs, IDs, or credentials.

predict_winrate

Which team wins this draft — CALIBRATED win probability for Dota 2, Deadlock or Marvel Rivals. Backed by batru.gg's per-game production models (built on 140M+ real matches and calibrated: a reported 60% reflects a real ~60% empirical win rate — not a guess). Hero names are normalised internally. Per-game semantics: - dota2: full OR partial drafts (0-5 per side); empty draft = 50/50. `my_side` says whether my_heroes are Radiant or Dire. - deadlock / marvel-rivals: requires the full 6v6 rosters; `my_side` is ignored. For partial drafts use recommend_pick instead. Args: game: "dota2", "deadlock", or "marvel-rivals" (required). my_heroes: Your team's heroes (list of names; may be empty). enemy_heroes: The enemy team's heroes (list of names). my_side: Dota only — "radiant" (default) or "dire". Returns calibrated win-rate percentages for both teams. Report them verbatim; do not adjust them. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

predict_winrate_batch

Score MANY candidate next-picks for a Dota 2 draft in ONE call — calibrated win rate + delta each. Use this instead of looping predict_winrate over candidates: the whole batch runs as a single model invoke server-side. For each candidate you get the CALIBRATED team win rate after adding it, plus the delta vs the draft without it (a full-roster sweep of up to 150 candidates fits in one call). Currently dota2-only. Args: my_heroes: Heroes your team already picked (0-4). enemy_heroes: Enemy heroes (0-5). candidates: Candidate heroes to evaluate (1-150). my_side: "radiant" (default) or "dire". game: Only "dota2" today. Returns {baseline_win_rate_pct, candidates:[{hero, shortName, win_rate_pct, delta_pp}]} sorted best-first. Report verbatim. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

recommend_pick

Best heroes to pick next against this draft — Dota 2, Deadlock or Marvel Rivals. Per-game semantics: - dota2: top 3 picks scored by the CALIBRATED draft model (each with the calibrated team win rate after adding that hero); `my_side` applies. - deadlock / marvel-rivals: ranked by REAL observed pair data (win rate vs the enemy heroes, blended with duo rate alongside your picks) — an empirical heuristic, not the calibrated model; verify a full 6v6 with predict_winrate. Args: game: "dota2", "deadlock", or "marvel-rivals". enemy_heroes: Enemy heroes to pick against. my_heroes: Heroes your team already has. my_side: Dota only — "radiant" (default) or "dire". limit: Max recommendations (Deadlock/Marvel; Dota returns top 3).

get_tier_list

Best heroes right now — the current-patch tier list for Dota 2, Deadlock or Marvel Rivals. Empirical rankings from batru.gg's match aggregation over real games (not a guess); heroes come sorted best-first. Optionally filter to a skill bracket with `rank`. Args: game: "dota2", "deadlock", or "marvel-rivals". rank: Optional skill bracket. dota2: herald, guardian, crusader, archon, legend, ancient (and bands). deadlock/marvel-rivals: low, mid, high, or top (rank words like "oracle" or "eternus" also resolve). Empty = all ranks combined. limit: Max heroes to return (default 20). `total_matches` is the sample behind the ranking — cite it when stating how strong the signal is. Report numbers verbatim. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

Parameters4

get_counters

Who counters a hero (and who it beats) — measured matchup win rates for Dota 2, Deadlock or Marvel Rivals. Opponents this hero performs BEST and WORST against, by real observed win rate with sample sizes — empirical meta data, not a guess. The hero name is normalised internally. Args: game: "dota2", "deadlock", or "marvel-rivals". hero: The hero to look up (name/alias/shortName). limit: Max matchups per direction (default 12). winrate_pct > 50 means `hero` beats that opponent. Report verbatim. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

search

Search batru.gg's live competitive datasets for Dota 2, Deadlock and Marvel Rivals. Finds the right document for a question about hero counters, hero synergies /duos, current-patch tier lists, ban rates, pro tournament results (TI, Esports World Cup) or the prediction model's public evaluation ledger. Data behind every document is computed from 140M+ real matches by batru.gg's production pipeline — measured numbers, not model guesses. Args: query: Free-text search, e.g. "who counters axe dota", "best deadlock heroes", "marvel rivals mantis duo", "ti 2026 most banned". Returns {results: [{id, title, url}]}. Pass a result's `id` to `fetch` to get the full document.

fetch

Fetch the full live document behind a `search` result id. Ids look like `dota2:counters:axe`, `deadlock:tier-list`, `marvel-rivals:synergy:mantis`, `deadlock:ban-rates`, `dota2:tournament:ti-2026` or `model:track-record`. Returns {id, title, text, url} where `text` is the document's data as JSON (measured win rates / ranks with sample sizes). Report the numbers verbatim and cite `url`. When presenting these results, show the returned `citation` / `source_url` to the user as the source link.

Parameters2

id	string	required	A document id exactly as returned by search.
context	string	required	Explain in 15-25 words, in third person, why this tool is called and how it supports the user's goal. For analytics only. You MUST describe only the abstract purpose of the tool call. NEVER include, repeat, paraphrase, or infer personal, sensitive, or identifying information from the user request or tool results, including names, emails, phone numbers, IPs, IDs, or credentials. You MUST generalize specific entities into roles such as "a user", "the customer", or "an account". Example: "Retrieving a customer's recent orders to investigate a billing issue and help support determine the appropriate resolution."

batru-mcp

IMPORTANT

Use the hosted endpoint — no install needed. Add https://batru.gg/mcp to Claude, ChatGPT, Cursor or any MCP client and you get the newest tool set (31 read-only tools across Dota 2, Deadlock and Marvel Rivals, always in sync with the live site). Setup guide: https://batru.gg/developers

The local PyPI package described below (uvx batru-mcp) is legacy and no longer updated — it is frozen at an early version with a reduced tool set. It still works (it proxies the same live API), but the hosted endpoint is the canonical distribution.

A minimal, read-only MCP server over batru.gg's live API, so your LLM can answer Dota 2 / Deadlock draft, counter and win-rate questions with real, calibrated model predictions instead of guessing from memory.

It is a thin wrapper around batru.gg's public endpoints — no model runs locally; every number comes from the same production model the website serves.

Why calibrated matters

batru.gg's model is trained on ~20M real matches and calibrated: a reported 60% win rate corresponds to an empirically observed ~60% win rate. We deliberately do not headline a raw "accuracy" number — accuracy alone is misleading for win prediction. What you get from these tools are probabilities you can trust at face value. The tool descriptions instruct the host LLM to report these numbers verbatim and never invent matchup data.

Tools

Tool	What it does
`lookup_hero(query, game="dota2")`	Normalise a name/alias/shortName to `{id, displayName, shortName}`. `game` ∈ {`dota2`, `deadlock`}.
`predict_dota_winrate(my_heroes, enemy_heroes, my_side="radiant")`	Calibrated win-rate % for both teams (partial drafts OK; empty → 50/50).
`recommend_dota_pick(my_heroes, enemy_heroes, my_side="radiant")`	Top-3 heroes to pick next, each with its calibrated win rate.
`get_dota_counters(hero, limit=12)`	Real matchup table: who this hero beats / loses to, with win rate % and sample size.
`predict_deadlock_draft(team0_heroes, team1_heroes)`	Calibrated win-rate % for a Deadlock 6v6 (6 heroes per team).

Hero names are accepted in any form (e.g. am, anti mage, Anti-Mage) and normalised internally — the backend silently drops names it doesn't recognise, so normalising first keeps predictions honest.

Install

Requires uv (or any way to run a Python 3.12+ package from PyPI):

bash

uvx batru-mcp           # fetches from PyPI and starts the stdio MCP server

Configuration is via the BATRU_API_BASE environment variable (default https://batru.gg) — you normally don't need to set anything.

Claude Desktop config

Add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

json

{
  "mcpServers": {
    "batru": {
      "command": "uvx",
      "args": ["batru-mcp"]
    }
  }
}

Restart Claude Desktop; the batru tools appear in the tool picker. Claude Code: claude mcp add batru -- uvx batru-mcp.

Development

bash

git clone https://github.com/batrugg/batru-mcp && cd batru-mcp
uv sync
uv run batru-mcp        # run the server from the checkout (blocks, waiting on stdin)

For a Claude Desktop pointing at the checkout, use "command": "uv", "args": ["run", "--directory", "/absolute/path/to/batru-mcp", "batru-mcp"].

Tests

bash

uv run pytest            # offline: hero normalisation + draft assembly
uv run pytest -m live    # also hits the real batru.gg API

Prefer programmatic access from Python instead of MCP? pip install batru — the official batru SDK.
