Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02590 | $0.02590 |
| Opus 5 | $0.01295 | $0.01295 |
| Sonnet 5 | $0.00518 | $0.00518 |
| Haiku 4.5 | $0.00259 | $0.00259 |
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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
apiKeyon every/mcpcall. On/mcp-oauth, the Bearer identity resolves the key — noapiKeyparameter. - 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=Fsuffix — bareES/NQare equities). Upper-case them. - For point-in-time / backtest questions, prefer the
get_historical_*tools (Alpha) withat=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_qualityon strategy-signal responses before presenting a trade; gate ondecision != insufficient_data.
Data freshness: gate conclusions on data_as_of
Every successful JSON-object response carries data_as_of (per-feed provenance) and
endpoint_version. Check it before stating a conclusion as current.
Identify the feeds the call actually depends on, and check only those.
| Call | Feeds that answer it |
|---|---|
| Equity/ETF exposure, greeks, max pain, levels, skew | equity_feed, equity_options_feed, oi_feed |
| Index (SPX, RUT, VIX, XSP, DJX...) | index_feed, index_options_feed, oi_feed |
| Futures (ES=F, NQ=F...) | futures_feed, futures_options_feed |
| Order flow, 0DTE flow, dealer risk | flow_feed |
| VIX / SKEW / MOVE / Fear & Greed context | macro_feed |
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.

flashalpha-mcp AGENTS.md is an instructions file published in the GitHub repository FlashAlpha-lab/flashalpha-mcp (1 stars, last pushed 6d ago), licensed MIT. It adds 2,590 tokens to every session, about $0.0129 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
