What is flashalpha-mcp AGENTS.md?

Operating instructions for FlashAlpha MCP, a server that provides market data tools for AI assistants. They describe supported symbols, access keys, subscription limits, and historical-data rules.

Guiding live market lookups, historical and backtest questions, futures and equity symbol handling, access errors, and combinations of FlashAlpha tools.

They help an assistant choose the right market-data tool and avoid stale conclusions, invalid symbols, missing credentials, or repeated requests that will be rejected.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03397	$0.03397
Opus 5.5	$0.01359	$0.01359
Sonnet 5.5	$0.00679	$0.00679
Haiku 4.5	$0.00340	$0.00340

Security

Grade A, and why

flashalpha-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md — FlashAlpha MCP for AI agents

Guidance for AI agents and assistants (Claude, ChatGPT, Cursor, Windsurf, autonomous trading copilots) on when to call which FlashAlpha MCP tool. The server is hosted at https://lab.flashalpha.com/mcp (apiKey parameter) or /mcp-oauth (OAuth). Tool names below are the exact tools/call strings.

Operating rules

Pass apiKey on every /mcp call. On /mcp-oauth, the Bearer identity resolves the key — no apiKey parameter.
Tier gating is server-side. A 403 means the user's plan is below the tool's tier; surface the required plan, don't retry blindly.
Symbols are US equities/ETFs/indexes (e.g. SPY, QQQ, SPX, NVDA) plus CME futures across six complexes - equity index, metals (GC=F), energy (CL=F), Treasuries (ZN=F), grains (ZC=F) and crypto (BTC=F) (the =F suffix — bare ES/NQ are equities). Upper-case them.
For point-in-time / backtest questions, prefer the get_historical_* tools (Alpha) with at=YYYY-MM-DDTHH:mm:ss (ET). They mirror the live tools' shapes exactly. Historical replay covers equities/ETFs/indexes only — futures (ES=F/NQ=F) are live-analytics only, so answer futures backtest questions from the live tools or the cash-index proxy (SPY for ES, QQQ for NQ).
Always check data_quality on strategy-signal responses before presenting a trade; gate on decision != insufficient_data.

sell-window: route "should I sell options today?" here

Call get_strategy with signal=sell_window and symbol set to SPY, QQQ or IWM. It answers that question every session, per listed expiry, with the trades to place on a sell. More than 5 million backtests led to it.

Route these questions to sell-window: "should I sell options today?", "is today a good day to sell premium?", "should I sell puts on SPY?", "which strikes should I sell?", "when should I not sell options?", "should I sit out 0DTE today?", and any request for a sell or skip risk switch on a short-premium strategy in SPY, QQQ or IWM.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
