## What is this?

The Model Context Protocol (MCP) lets AI assistants call external data tools instead of guessing from training data. Equibles exposes US stock market and financial data as an MCP server: use it hosted at `https://mcp.equibles.com/mcp` (free API key, or OAuth with no key at all), or run it yourself from the open-source stack. Everything is parsed from the primary sources (SEC EDGAR, FINRA, FRED, CFTC, CBOE, USAspending, company IR sites), not from third-party estimates.

## Quickstart (hosted, 30 seconds)

1. Create a free account at [equibles.com](https://equibles.com) — no credit card required.
2. Create an API key at [`https://equibles.com/dashboard/apikeys`](https://equibles.com/dashboard/apikeys). It starts with `eq_` and is shown once, so copy it right away.
3. Connect your client with the URL `https://mcp.equibles.com/mcp` (see below).

ChatGPT and Claude (web and Desktop) can skip the key entirely and sign in over OAuth.

## Connect your AI client

### Claude Desktop / Claude web (claude.ai)

Settings → Connectors → Add custom connector → URL `https://mcp.equibles.com/mcp` → sign in over OAuth (no key needed).

Key alternative: use the URL `https://mcp.equibles.com/mcp?api_key=eq_your_api_key`.

### Claude Code

```bash
claude mcp add --transport http equibles https://mcp.equibles.com/mcp
```

Then run `/mcp` and choose **Authenticate** to sign in over OAuth.

Key alternative:

```bash
claude mcp add-json equibles '{"type":"http","url":"https://mcp.equibles.com/mcp","headers":{"Authorization":"Bearer eq_your_api_key"}}' --scope user
```

### ChatGPT

Add a developer-mode connector with URL `https://mcp.equibles.com/mcp` and complete the OAuth sign-in (or use the `?api_key=eq_your_api_key` URL).

### Cursor

Add to `~/.cursor/mcp.json`:

```json
{ "mcpServers": { "equibles": { "url": "https://mcp.equibles.com/mcp", "headers": { "Authorization": "Bearer eq_your_api_key" } } } }
```

### VS Code (Copilot)

```bash
code --add-mcp '{"name":"equibles","type":"http","url":"https://mcp.equibles.com/mcp"}'
```

Or add a `.vscode/mcp.json` with a `"servers"` object using the same URL and `Authorization` header shape:

```json
{ "servers": { "equibles": { "type": "http", "url": "https://mcp.equibles.com/mcp", "headers": { "Authorization": "Bearer eq_your_api_key" } } } }
```

### Any MCP client

Use the HTTP transport with URL `https://mcp.equibles.com/mcp`, authenticating with an `Authorization: Bearer eq_...` header or a `?api_key=eq_...` query parameter.

After connecting, see the full per-client guides at [https://equibles.com/docs/mcp](https://equibles.com/docs/mcp).

## Pricing & rate limits

| Plan | Daily requests | Price | Card required |
|---|---|---|---|
| Free | 100 requests/day | $0 | No |
| Pro | 10,000 requests/day | See [pricing](https://equibles.com/pricing) | Yes |

- One shared daily counter across both the MCP server and the REST API; it resets at 00:00 UTC.
- Rate-limit headers are exposed on responses: `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`, and `Retry-After` (on 429).
- When you go over the limit, the MCP server answers in-band with a normal tool result explaining the limit rather than returning an opaque error, so your agent can read and react to it.

Details at [https://equibles.com/pricing](https://equibles.com/pricing).

## Self-host with Docker (open source)

The full stack is open source at [https://github.com/daniel3303/Equibles](https://github.com/daniel3303/Equibles).

```bash
git clone https://github.com/daniel3303/Equibles
cd Equibles
docker compose up
```

The MCP server comes up at `http://localhost:8081/mcp`. No API key is required by default; set the `MCP_API_KEY` environment variable to require an `Authorization: Bearer ` header. When self-hosting, the Bearer header is the only auth method (no query parameter, no OAuth).

The self-hosted server exposes the 62-tool open-source subset: 13F holdings, insider trading, SEC filings and fundamentals, funds/ETFs/advisers, FRED, CFTC, CBOE, congressional trades, short data, stock prices, and the FDA calendar. The hosted server adds the commercial layers on top: earnings calls, guidance, KPIs, the screener, valuation multiples, buybacks, executive data, and a few more.

Note: the self-hosted stack runs its own scrapers against the primary sources, so the databases start empty and fill up over time after you start it.

## REST API

Everything is also available as a conventional REST API at `https://api.equibles.com/v1`, sharing the same API key and daily limit as the MCP server. Docs at [https://equibles.com/docs](https://equibles.com/docs).

## Data sources & methodology

Every dataset is parsed from the primary source, never from third-party estimates:

- **SEC EDGAR** — filings, XBRL fundamentals, 13F holdings, Forms 3/4/5/144, NPORT, ADV, N-CEN, Form D
- **FINRA** — short volume, short interest, dark-pool / off-exchange volume
- **FRED** — economic indicators and macro series
- **CFTC** — Commitments of Traders futures positioning
- **CBOE** — put/call ratios and VIX
- **USAspending.gov** — federal government contract awards
- **Company IR sites** — investor-relations news and events
- **Congressional disclosures** — member trades and net worth
