## 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 |

- **Transport:** Streamable HTTP
- **Protocol version:** MCP 2025-06-18
- **OAuth discovery:** [`https://lab.flashalpha.com/.well-known/oauth-protected-resource`](https://lab.flashalpha.com/.well-known/oauth-protected-resource) (RFC 9728)
- **Authorization server:** `https://flashalpha.com/oauth`

### 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.

## Quick Setup (self-hosted clients → `/mcp` + `apiKey`)

### Claude Desktop

Edit `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows):

```json
{
  "mcpServers": {
    "flashalpha": {
      "type": "http",
      "url": "https://lab.flashalpha.com/mcp"
    }
  }
}
```

### Claude Code CLI

```bash
claude mcp add flashalpha --transport http https://lab.flashalpha.com/mcp
claude mcp list
```

### Cursor

**Settings → MCP** → Add server:

```json
{
  "flashalpha": {
    "transport": "http",
    "url": "https://lab.flashalpha.com/mcp"
  }
}
```

### VS Code (Copilot / Continue)

`.vscode/mcp.json` or user settings:

```json
{
  "servers": {
    "flashalpha": {
      "type": "http",
      "url": "https://lab.flashalpha.com/mcp"
    }
  }
}
```

### Windsurf

**Cascade settings → MCP Servers**:

```json
{
  "flashalpha": {
    "transport": "http",
    "url": "https://lab.flashalpha.com/mcp"
  }
}
```

### 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](https://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:

| | |
|---|---|
| RFC 9728 protected-resource metadata | `https://lab.flashalpha.com/.well-known/oauth-protected-resource` |
| OIDC discovery | `https://flashalpha.com/oauth/.well-known/openid-configuration` |
| JWKS | `https://flashalpha.com/oauth/.well-known/jwks` |
| Dynamic Client Registration | `POST https://flashalpha.com/oauth/register` |
| Authorization endpoint | `https://flashalpha.com/oauth/authorize` |
| Token endpoint | `https://flashalpha.com/oauth/token` |
| Scope | `flashalpha.mcp` |

## Data provenance: `data_as_of`

Every tool result carries the API's response envelope: `data_as_of`, reporting when each
upstream feed last delivered to the node that answered, and `endpoint_version` identifying
the deployment that produced it.

| Field | Feed | Expected cadence |
|---|---|---|
| `node` | Which node answered | Nodes hydrate independently |
| `equity_feed` | Equity and ETF spot quotes | seconds, during market hours |
| `equity_options_feed` | Equity and ETF option quotes | seconds, during market hours |
| `index_feed` | Index spot (SPX, RUT, VIX and the other index roots) | seconds, during market hours |
| `index_options_feed` | Index option quotes | seconds, during market hours |
| `futures_feed` | Futures prices | seconds, during the futures session |
| `futures_options_feed` | Futures option quotes | seconds, during the futures session |
| `flow_feed` | Classified options and stock trade tape | seconds, during market hours |
| `oi_feed` | Settled open interest | daily, dated to the prior 16:00 ET close |
| `macro_feed` | VIX, VVIX, SKEW, MOVE, SPX, Fear & Greed | minutes; reports its OLDEST component |

This matters more for an MCP client than for a normal SDK caller: a model reading a tool
result has no other way to tell a current figure from a stale one, and will otherwise
present both with equal confidence.

### How to read it

- **Check the feeds the tool depends on.** A GEX call on an equity is answered from
  `equity_feed`, `equity_options_feed` and `oi_feed`. `futures_feed` being `null` in that
  result says nothing about the answer.
- **Compare against the cadence, not the clock.** `oi_feed` at the previous session's
  close is correct: settled open interest is published once per session, so on a Monday
  the newest figure that exists is Friday's. An options feed an hour behind during the
  regular session is not correct.
- **`null` means "not seen on this node", not "broken".** A node that has never been
  asked for a futures symbol has never opened that feed.
- **Spot and options are separate on purpose.** They arrive over different pipes and can
  fail independently, so an index chain can be current while the index level behind it is
  not.
- **It evidences feed activity, not per-contract freshness.** An illiquid strike may not
  have quoted for hours while its feed is healthy.
- **`data_as_of` is not `as_of`.** `as_of` is response-generation time or the newest
  contract in the payload, depending on the endpoint. `data_as_of` describes the feeds
  behind it.

Historical replay tools carry a second object, `archive_as_of`, in the same shape: the
vintage of the archive rows actually replayed for the timestamp requested. Their
every feed in `data_as_of` is `null`, because a replay node reads the archive and consumes no live
feed.

### Futures (CME)

FlashAlpha serves the full options-analytics stack for **CME futures** across six complexes - equity index (`ES=F`, `NQ=F`, `RTY=F`, `YM=F`, `MES=F`, `MNQ=F`), metals (`GC=F` gold, `SI=F` silver), energy (`CL=F` crude oil, `NG=F` natural gas), the Treasury curve (`ZT=F`, `ZF=F`, `ZN=F`, `TN=F`, `ZB=F`, `UB=F`), grains (`ZC=F` corn, `ZS=F` soybeans, `ZW=F` wheat) and crypto (`BTC=F` bitcoin). Options-on-futures are priced with **Black-76** (forward-priced) and each root carries its own CME contract multiplier, so notionals and dollar gamma are in real dollars. Note the quote conventions: Treasuries are quoted in points of par and grains in cents, so their multipliers are the contract size divided by 100. 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:

```json
{ "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/GC%3DF`); SDK methods take the plain string `"GC=F"`. Futures symbols require the Growth plan or higher. 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 2017-01-03. 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.

## What the paid tiers unlock

The free tier covers single-expiry GEX on equities, key levels, the BSM Greeks/IV
calculator and stock quotes. Paid tiers add:

- **DEX, VEX (vanna) and CHEX (charm) exposure, plus max pain** — from the **Basic tier**
  ($79/mo), with ETF and index symbols.
- **Full-chain GEX, 0DTE and flow analytics** — from the **Growth tier** ($299/mo).
- **Point-in-time replay since 2017, SVI vol surfaces, VRP analytics, higher-order Greeks**,
  uncached and unlimited — the **Alpha tier** ($1,499/mo). FlashAlpha is one of the only
  public APIs publishing aggregate vanna and charm exposure across the full universe, with
  no look-ahead and no training-serving skew.
