quant-swarm vs. the data servers
The short version
Data MCPs move numbers; quant-swarm answers questions. Alpha Vantage, Financial Modeling Prep, EODHD, Polygon and Financial Datasets expose prices, filings and fundamentals as tool calls — excellent when you know what you want and what to do with it. quant-swarm is a validation layer on top of that stage of your work: “is this signal real?”, “will this order breach risk limits?”, “does my genome survive a drawdown regime?”, and a benchmark tournament before any promotion claim. You can run both: use a data server for raw inputs and quant-swarm for derived verdicts and gates.

| Question | Data MCPs (Alpha Vantage, FMP, EODHD, Polygon, Financial Datasets) | quant-swarm |
|---|---|---|
| What does a tool call return? | Raw series/events: quotes, technical indicators, filings, fundamentals, news. | Derived-only answers: verdicts, ranks, labels, gating decisions. No raw provider values are ever echoed. |
| “Is this signal real?” | Out of scope — data exits; the significance question is yours. |
pit.analysis: every family explained with rolling IR,
an overlap-corrected p, observation count, and an explicit verdict tied to the
funnel's gate.
|
| Point-in-time guarantee | Varies by endpoint; vintage semantics are the caller's problem (see each provider's series API docs). | Every dataset dated by its public release event; point-in-time is enforced in the store and refused otherwise. |
| Multiple-testing / overlapping-window correction | Not applicable to raw data. | Benjamini-Hochberg across all families + Newey-West inference on overlapping horizons + shuffled-date placebo. |
| Pre-trade risk gates | Out of scope. | Warden checkers pinned by tests against the live risk engine's floors. |
| Benchmark before promotion | Out of scope. | Shadow Tournament: hosted, paired champion-vs-challenger runs, credit-metered. |
| Free tier | Mostly freemium API keys with rate limits (e.g. Alpha Vantage's free key tier). |
Free token instantly; lite answers incl. pit.analysis;
hosted compute is Pro.
|
| Install | stdio servers/API keys; a few hosted URLs. |
stdio uvx + hosted remote with OAuth 2.1 + PKCE.

When to use them instead
If you need raw OHLCV depth, fundamental statement level detail, options chains or tick-level news feeds, a data MCP is the right tool — that is exactly the input layer quant-swarm refuses to duplicate. The warden and gym tools accept caller-supplied bars for exactly that reason: bring data from wherever you get it, and let the validation layer answer the questions a data API cannot.
