概覽

AI 產生的概覽

託管式 MCP 伺服器，用數千次比賽模擬為 MLB、WNBA、PGA 與 ATP 投注評分，給出模擬機率、隱含機率與優勢值。

可以做什麼
  • 以純文字送出單注或多腿串關，取得每一腿的模擬機率、博彩公司賠率隱含機率以及兩者間的優勢值
  • 查詢 MLB、WNBA、PGA、ATP 目前是否有可檢查的賽程，免費
  • 查看剩餘投注檢查次數以及下一次額度釋放時間，同樣免費
  • 逐腿評分並將串關投注整體定價
適用情境
適合讓助理用模擬比賽結果核對某個運動投注或串關，而不是依賴模型憑記憶猜測，並判斷賠率是否留有優勢。它只為你指定的投注定價，不會在盤口中主動尋找價值。
執行需求
遠端 Streamable HTTP 端點，無需在本機安裝或執行。匿名使用不需要 API 金鑰或註冊。可選擇以 Authorization Bearer 標頭送出已登入使用者的存取權杖，以取得較高額度。
安裝前請注意
匿名使用共用每裝置每天 100 次檢查的額度；登入後為每小時 1000 次。只有投注被完整評分時才會消耗一次檢查。送出存取權杖意味著把憑證交給該服務；無效或過期的權杖會回傳 401。此服務不收注、不賣推薦，輸出為模擬機率而非保證。

README

NegativeEV MCP server

Grade any MLB, WNBA, PGA or ATP bet against thousands of play-by-play game simulations, from inside your AI client.

Whether a bet is worth taking depends on tonight's lineups, today's injuries, and the weather at first pitch. None of that is in a model's weights. Asked cold, a model answers fluently and wrongly. This server returns a probability counted from simulations of the actual game: each leg's simulated win probability, the probability the sportsbook's price implies, and the edge between them.

This is a hosted remote server. There is nothing to build or run from this repo. The repo is the server's public face and carries a mirror of its registry record (server.json).

Connect

No API key, no signup. Anonymous calls work immediately. The server speaks plain Streamable HTTP, so any MCP client can connect to https://negativeev.com/mcp.

Tools

ToolWhat it does
check_betGrades a bet written as plain text, including a multi-leg parlay in one string. Returns each leg's simulated probability, the implied probability from the price, and the edge. It prices a bet you name. It does not search the board for value.
get_slateSays whether there is a checkable slate right now. Free. Spends no check.
get_usageReports checks remaining and when the next frees up. Free. Spends no check.

Call get_slate first to confirm there is a checkable slate. check_bet spends one of the caller's checks only when the bet fully grades, and every result says so outright in its status and check_spent fields. A bet that comes back ungraded was understood. It is simply not on the simulated slate, so re-sending it with different wording returns the same answer. Check get_slate instead.

Limits and auth

Anonymous calls share a per-device quota of 100 checks a day, on its own counter. Signing in makes checks unlimited, with a pace cap of 1000 checks an hour. Send a signed-in user's access token as Authorization: Bearer. Details at negativeev.com/auth.md. An invalid or expired token is rejected with a 401 rather than silently downgraded, so re-authenticate rather than retrying anonymously.

check_bet

Check a bet

Check a specific sports bet against thousands of play-by-play game simulations: each leg's simulated probability, the sportsbook's implied probability, and the edge. Send the bet as plain text - teams or players, market, line, odds. A parlay in one string is graded leg by leg and priced as a whole. Call this first; nothing has to be set up, and a missing slate, an unrecognized bet, or an unsupported market comes back as a plain `status` without spending a check. It prices a bet the caller names and never suggests one, so there is nothing to send for "what should I bet tonight". Every result leads with `status` and `check_spent` and says whether re-wording would change anything; when it says no, it means no. Covers MLB, WNBA, PGA, and ATP. A game that already started still checks, against the simulations from before it began.

輸入參數bet必填

get_slate

Today's slate

Which of MLB, WNBA, PGA, and ATP have a checkable slate right now - at least one simulated game that has not started. Pass `sport` for one; omit it for all. Free, spends no check. It is not required before `check_bet`, which reports a missing slate itself at no cost. Call it to answer "what can be checked today", or after a `no_slate` or `ungraded` result, which mean the game is not on the simulated slate rather than that the bet was worded wrong.

輸入參數sport

get_usage

Checks remaining

How many bet checks the caller has left and when the next one frees up - 100 a day shared per device anonymously, 1000 an hour with a signed-in user's token. Free, spends no check. It grades nothing, so it is not a step before a check: call it when a check comes back refused for quota, or before working through a long list of bets.

無需輸入參數。
