Summary

Persona endpoints are the detail that makes 70 tools workable.

A catalogue this size would otherwise swamp a model's tool list; pointing at `/mcp/0dte` or `/mcp/volarb` loads only what that style of trading needs. The analytics are the real draw — dealer gamma, vanna and charm exposure computed for you, rather than a chain you have to reduce yourself. Check the tier table against what you actually plan to call, because the free key is a taste rather than a working setup.

What it is

A hosted options-analytics server with more than 70 tools, reached over streamable HTTP. It covers dealer positioning, volatility structure, real-time order flow and earnings, and returns computed analytics rather than raw chains. The repository holds the documentation and configuration; the server itself is closed-source and runs at lab.flashalpha.com.

What you get

Exposure: `get_gex`, `get_dex`, `get_chex`, max pain and key dealer-positioning levels, plus `get_exposure_sheet` and `get_exposure_basket` across symbols
Volatility: IV surfaces with SVI parameters, skew and term structure, spot-vol correlation, `get_advanced_volatility` and VRP with history
Order flow: `get_flow_live`, `get_flow_scan`, `get_flow_signals`, `get_dealer_premium`, `get_flow_pin_risk` — sweeps, blocks and dealer premium as they happen
0DTE intraday flow as snapshot, time series, hedge flow, heatmap and strike flow
Ten strategy signals as their own tools, including `flow_anomaly`, `dealer_regime`, `expiry_positioning`, `surface_anomaly` and `tail_pricing`
Earnings suite: `get_earnings_calendar`, `get_earnings`, `get_earnings_screener`, expected move, IV crush and dealer positioning around the print
`calculate_greeks` and `calculate_kelly` for Black-Scholes greeks and position sizing, plus multi-leg structure P&L
Nine persona endpoints — `/mcp/gex`, `/mcp/0dte`, `/mcp/volarb`, `/mcp/earnings` and others — that load a curated subset instead of the whole catalog

Requirements

Nothing to install. Point your client at https://lab.flashalpha.com/mcp and pass `apiKey` on each tool call, or use https://lab.flashalpha.com/mcp-oauth for hosts that require OAuth 2.1 with PKCE and dynamic client registration, where no key parameter is needed. A free key gives 5 calls a day on 15-minute-delayed data; paid tiers raise the quota and the freshness, with real-time and the historical replay on the top plan. Tier gating is enforced per tool — a call above your plan returns a 403 naming the plan required.

Setup effort

One command plus a key — claude mcp add flashalpha --transport http https://lab.flashalpha.com/mcp, then supply credentials
