Real-time & historical options analytics: GEX, dealer positioning, vol, VRP, 0DTE, CME futures

已驗證Streamable HTTP可網頁執行金融資料與分析

概覽

AI 產生的概覽

遠端 MCP 伺服器,提供即時與歷史選擇權分析:造市商曝險(GEX/DEX/VEX/CHEX)、波動率、VRP、0DTE、資金流與財報資料。

可以做什麼
  • 查詢即時造市商曝險與關鍵價位:GEX、DEX、VEX、CHEX、曝險表、gamma 翻轉點、買權/賣權牆、最大痛點與 0DTE 分析
  • 讀取波動率資料:隱含波動率曲面與 SVI 參數、已實現波動率、VRP 儀表板與歷史、偏斜、期限結構、現貨-波動率相關性、離散度
  • 檢視訂單流:選擇權與股票成交、大單、掃單、造市商權利金、跨標的資金流排行與 0DTE 資金流
  • 在全市場篩選與排序標的,並執行財報分析、財報行事曆與財報篩選器
  • 取得十種選擇權策略訊號的決策結果,以及純數學的 Black-Scholes 希臘值、隱含波動率求解、Kelly 部位規模與多腳組合損益
  • 以分鐘為單位回放 2018 年 4 月以來的歷史分析資料,用於回測
適用情境
適合需要選擇權市場脈絡的任務:造市商部位與 gamma 價位、波動率與 VRP 判讀、0DTE 布局、財報隱含波動、資金流掃描,或用於回測的歷史回放。與金融無關的一般任務不需要安裝。
執行需求
遠端 Streamable HTTP 端點,無需本機安裝。提供兩個端點:一個在每次工具呼叫時傳入 apiKey 參數,另一個使用 OAuth 2.1(PKCE 與動態用戶端註冊)。需要服務商帳號與 API 金鑰;ETF 與指數、全鏈 GEX、0DTE、波動率分析與歷史回放等功能需付費方案,且有每日呼叫配額。
安裝前請注意
多數功能需付費訂閱,並依方案限制每日呼叫次數與資料新鮮度。apiKey 以工具參數逐次傳遞,會出現在工具參數與對話脈絡中。市場資料僅供參考,不構成投資建議;結果附有 data_as_of 新鮮度資訊,引用數字前應先確認。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Flashalpha,將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable,透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式,或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南,先向你展示發布者、端點和登入方式,經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.tdobrowolski1%2Fflashalpha/install.md,並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前,先告訴我它的發布者、端點和登入方式,等我確認。不要把 API 金鑰寫進命令或我會提交的檔案;問我金鑰應從哪裡取得。

What is this repo

Documentation, setup snippets, and server.json metadata for the FlashAlpha remote MCP server. The server itself runs at https://lab.flashalpha.com/mcp (and /mcp-oauth for OAuth-authenticated clients) — its source is not open. Use this repo as a reference for how to wire FlashAlpha into your AI client of choice.


Server URLs

Two endpoints, identical tool catalog, different authentication:

EndpointAuthWhen to use

https://lab.flashalpha.com/mcp-oauthOAuth 2.1 + PKCE + DCR (RFC 7591)Claude Connector Directory, ChatGPT Apps, Perplexity custom connectors, any host that requires OAuth-authenticated remote MCP

Persona-scoped endpoints

Each base endpoint also has nine persona variants that expose a curated subset of the catalog for a specific trading style. Same auth model — /mcp/<persona> takes the apiKey parameter, /mcp-oauth/<persona> uses OAuth. Point your client at a persona URL instead of the base URL to load just that toolset.

Authentication

/mcp (apiKey)

Every tool call takes apiKey as a string parameter. Get a free key at flashalpha.com.

apiKey: "fa_your_key_here"

Key passes per-call rather than in a header so it works uniformly across all MCP clients without transport-level configuration.

/mcp-oauth (Bearer)

OAuth 2.1 + PKCE + Dynamic Client Registration (RFC 7591). The client registers itself, walks the authorization-code + PKCE flow, and presents a Bearer JWT on each request. No apiKey parameter needed — the server resolves the user's account from the OAuth identity and forwards the API key internally for upstream /v1/* calls. Same per-user tier gating and rate limits apply as the apiKey flow.

Data provenance: data_as_of

Every tool result carries the API's response envelope: data_as_of, reporting when each upstream feed last delivered to the node that answered, and endpoint_version identifying the deployment that produced it.

FieldFeedExpected cadence
nodeWhich node answeredNodes hydrate independently
equity_feedEquity and ETF spot quotesseconds, during market hours
equity_options_feedEquity and ETF option quotesseconds, during market hours
index_feedIndex spot (SPX, RUT, VIX and the other index roots)seconds, during market hours
index_options_feedIndex option quotesseconds, during market hours
futures_feedFutures pricesseconds, during the futures session
futures_options_feedFutures option quotesseconds, during the futures session
flow_feedClassified options and stock trade tapeseconds, during market hours
oi_feedSettled open interestdaily, dated to the prior 16:00 ET close
macro_feedVIX, VVIX, SKEW, MOVE, SPX, Fear & Greedminutes; reports its OLDEST component

This matters more for an MCP client than for a normal SDK caller: a model reading a tool result has no other way to tell a current figure from a stale one, and will otherwise present both with equal confidence.

How to read it

  • Check the feeds the tool depends on. A GEX call on an equity is answered from equity_feed, equity_options_feed and oi_feed. futures_feed being null in that result says nothing about the answer.
  • Compare against the cadence, not the clock. oi_feed at the previous session's close is correct: settled open interest is published once per session, so on a Monday the newest figure that exists is Friday's. An options feed an hour behind during the regular session is not correct.
  • null means "not seen on this node", not "broken". A node that has never been asked for a futures symbol has never opened that feed.
  • Spot and options are separate on purpose. They arrive over different pipes and can fail independently, so an index chain can be current while the index level behind it is not.
  • It evidences feed activity, not per-contract freshness. An illiquid strike may not have quoted for hours while its feed is healthy.
  • data_as_of is not as_of. as_of is response-generation time or the newest contract in the payload, depending on the endpoint. data_as_of describes the feeds behind it.

Historical replay tools carry a second object, archive_as_of, in the same shape: the vintage of the archive rows actually replayed for the timestamp requested. Their every feed in data_as_of is null, because a replay node reads the archive and consumes no live feed.

Futures (CME)

FlashAlpha serves the full options-analytics stack for CME futures across six complexes - equity index (ES=F, NQ=F, RTY=F, YM=F, MES=F, MNQ=F), metals (GC=F gold, SI=F silver), energy (CL=F crude oil, NG=F natural gas), the Treasury curve (ZT=F, ZF=F, ZN=F, TN=F, ZB=F, UB=F), grains (ZC=F corn, ZS=F soybeans, ZW=F wheat) and crypto (BTC=F bitcoin). Options-on-futures are priced with Black-76 (forward-priced) and each root carries its own CME contract multiplier, so notionals and dollar gamma are in real dollars. Note the quote conventions: Treasuries are quoted in points of par and grains in cents, so their multipliers are the contract size divided by 100. Everything that works for an equity works for futures: gamma exposure (GEX), DEX, VEX, CHEX, key levels, max pain, the IV surface, exposure summary, narrative, and live flow.

Call any live tool with the futures symbol — e.g. get_gex with symbol: "ES=F" returns gamma exposure for the E-mini S&P 500 future:

json
{ "symbol": "ES=F" }

Use the =F suffix - bare ES/NQ are equities, not futures. In raw REST paths URL-encode the = as %3D (e.g. GET /v1/exposure/gex/GC%3DF); SDK methods take the plain string "GC=F". Futures symbols require the Growth plan or higher. Historical replay for futures is coming; live analytics are available now.


Historical replay tools (17, Alpha tier)

All historical tools take a required at=YYYY-MM-DDTHH:mm:ss parameter (ET wall-clock) and replay the matching live analytic at any minute since 2017-01-03. Response shapes are identical to the live counterparts — backtesting code that parses live responses works on historical with a tool-name swap.

Note: The multi-factor options screener is now exposed as the post_screener MCP tool (with get_screener_fields for the field taxonomy), in addition to POST /v1/screener. The historical replay tools cover analytics only; for raw historical tick data use the historical REST endpoints directly.

  • Full-chain GEX, 0DTE and flow analytics — from the Growth tier ($299/mo).
  • Point-in-time replay since 2017, SVI vol surfaces, VRP analytics, higher-order Greeks, uncached and unlimited — the Alpha tier ($1,499/mo). FlashAlpha is one of the only public APIs publishing aggregate vanna and charm exposure across the full universe, with no look-ahead and no training-serving skew.
