How do I use FlashAlpha MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@FlashAlpha MCP Server show me the gamma exposure for AAPL" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

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:

Endpoint	Auth	When to use
`https://lab.flashalpha.com/mcp`	`apiKey` tool parameter	Self-hosted clients: Claude Desktop, Claude Code CLI, Cursor, Windsurf, VS Code Copilot
`https://lab.flashalpha.com/mcp-oauth`	OAuth 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.

Perplexity (Pro/Max/Enterprise)

Settings → Connectors → + Custom connector → Remote

URL: https://lab.flashalpha.com/mcp-oauth
Auth: OAuth (walks the consent flow at flashalpha.com/oauth/login)

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.

Discovery + endpoints:

Futures (CME equity-index)

FlashAlpha serves the full options-analytics stack for CME equity-index futures — ES=F (E-mini S&P 500) and NQ=F (E-mini Nasdaq-100). Options-on-futures are priced with Black-76 (forward-priced) using the correct CME contract multipliers. 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:

{ "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/ES%3DF); MCP tools take the plain string "ES=F". 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 2018-04-16. Response shapes are identical to the live counterparts — backtesting code that parses live responses works on historical with a tool-name swap.

Tool	Mirrors
`get_historical_gex`	`get_gex`
`get_historical_dex`	`get_dex`
`get_historical_vex`	`get_vex`
`get_historical_chex`	`get_chex`
`get_historical_levels`	`get_levels`
`get_historical_exposure_summary`	`get_exposure_summary`
`get_historical_narrative`	`get_narrative`
`get_historical_zero_dte`	`get_zero_dte`
`get_historical_max_pain`	`get_max_pain`
`get_historical_volatility`	`get_volatility`
`get_historical_advanced_volatility`	`get_advanced_volatility`
`get_historical_vrp`	`get_vrp`
`get_historical_surface`	`get_surface`
`get_historical_stock_quote`	`get_stock_quote`
`get_historical_option_quote`	`get_option_quote`
`get_historical_stock_summary`	`get_stock_summary`
`get_historical_coverage`	List symbols backfilled with coverage windows and gaps — call first to check whether (symbol, date range) is queryable

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.

MCP Resources (5)

The server publishes 5 markdown documents as MCP Resources so connected clients can pull the full reference into context with one call instead of relying on tool descriptions:

URI	Title
`flashalpha://docs/api`	Live API reference (every REST endpoint at api.flashalpha.com)
`flashalpha://docs/historical`	Historical replay reference
`flashalpha://docs/mcp`	This document
`flashalpha://docs/screener`	Live screener spec (filter DSL, sorts, formulas)
`flashalpha://docs/screener-fields`	Screener field taxonomy

MCP Prompts (4)

Canonical workflow templates that surface in Claude Desktop / Cursor / Windsurf UI as one-click recipes:

Prompt	Description
`analyze_exposure(symbol)`	Full dealer-positioning walkthrough — gamma regime, key levels, hedging pressure, 0DTE contribution
`vrp_regime_check(symbol)`	VRP percentile, IV-vs-RV richness, strategy scoring conditioned on the gamma regime
