Equibles

Equibles is a self-hosted, open-source financial data MCP server — an open-source alternative to a Bloomberg Terminal, built for AI agents rather than humans. It scrapes, stores, and serves SEC filings and XBRL financials, 13F institutional holdings, insider and congressional trades, FINRA/SEC short data, FRED economic indicators, CFTC and CBOE positioning, fund filings, government contracts, and daily stock prices — and exposes all of it over the Model Context Protocol, so Claude, ChatGPT, Cursor, or any agent can query it directly. Runs on your own hardware with Docker, for free, forever.

This is the open-source core of Equibles. Equibles Cloud runs this exact core and adds 33 more tools, 97 in total — earnings call transcripts and audio, real-time quotes, options chains with Greeks, LLM-extracted KPIs and guidance, buybacks, IPO filings, executive changes, valuation multiples, and a full US-market screener. Same protocol, same tool names, nothing to run — see what's included.

Don't want to run anything? Point your AI assistant at https://mcp.equibles.com/mcp and get a free API key at equibles.com/mcp — 100 requests/day, no card. Per-client setup guides live at daniel3303/stock-market-mcp-server.

See docs/ for the user guide and technical documentation.

Why Some Data Is Cloud-Only

Nothing above is held back from this repo. The cloud-only rows are data whose production needs infrastructure you would not stand up at home:

• Transcripts and audio — earnings calls are webcasts, not filings. Each one has to be discovered and recorded by a browser fleet, then put through GPU speech-to-text with speaker diarization, every call, every quarter.
• Live quotes and options chains — licensed real-time feeds, plus an always-on streaming service to fan them out. Neither the licence nor the uptime fits in a container on a laptop.
• KPIs, guidance, buybacks, IPO terms, executives, risk flags — pulled out of filings, proxies, and earnings releases by LLM extraction lanes with verification passes and a human review queue, which needs sustained inference capacity.
• Investor-relations events and news — collected from thousands of company IR sites, needing the same stealth browser fleet as the webcasts.
• Multiples, screener, smart money, market context — derived, and only meaningful over a fully backfilled corpus of the whole market rather than the tickers you happen to have scraped so far.

Beyond the data, the cloud is already backfilled and kept current, and it is managed — no scrapers to babysit. This repo is free forever under AGPL-3.0; the cloud has a free tier at 100 requests/day with no card.

Start on the free tier, and self-host whenever you'd rather own the stack.

Quick Start

Docker Compose (recommended)

The fastest way to get everything running. Requires Docker.

git clone https://github.com/daniel3303/Equibles.git
cd Equibles
cp .env.example .env
# Edit .env and set SEC_CONTACT_EMAIL (required by SEC EDGAR fair access policy)
docker compose up

This starts:

Service	Port	Description
db	5432	ParadeDB (PostgreSQL + pgvector + pg_search)
web	8080	Web portal for browsing data
mcp	8081	MCP server for AI assistants
worker	—	Scrapers (SEC, FINRA, Congress, FRED, Yahoo, CFTC, CBOE, USAspending, FDA)

Data scraping starts automatically. SEC filings, holdings, insider trades, and congressional trades will begin populating within minutes.

Configuration

All settings can be configured via a .env file in the project root (recommended for Docker) or environment variables.

FINRA Short Data (free API key required):

The FINRA scraper (short volume and short interest) requires a free API key. Without it, the scraper skips gracefully and all other scrapers run normally. Fails-to-deliver data comes from SEC and works without FINRA credentials.

To get a key:

1. Go to the FINRA API Console and sign in (a Google account works)
2. Open the API Credentials menu and create a new API Key
3. Copy the Client ID and Client Secret
4. Set Finra__ClientId and Finra__ClientSecret in your .env file or environment variables

The older developer.finra.org "Teams & Apps" flow has been retired — use the API Console above.

FRED Economic Data (free API key required):

The FRED scraper requires a free API key from the Federal Reserve Bank of St. Louis. Without it, the scraper skips gracefully and all other scrapers run normally.

To get a key:

1. Register at fred.stlouisfed.org/docs/api/api_key.html
2. Copy the 32-character API key
3. Set Fred__ApiKey in your .env file or environment variables

Ticker Filtering (optional):

By default, all tickers are synced. To limit data syncing to specific stocks, set a single ticker list that applies to all scrapers:

# .env — sync only these tickers (applies to all scrapers)
Worker__TickersToSync__0=AAPL
Worker__TickersToSync__1=MSFT
Worker__TickersToSync__2=GOOGL

When not set, all stocks are synced.

Minimum Sync Date (optional):

By default, all scrapers start from January 2020. Set a more recent date for faster initial sync, or go as far back as 2000-01-01 for more historical data:

# .env — start syncing from 2024 instead of 2020
Worker__MinSyncDate=2024-01-01

Embedding (opt-in):

Setting	Default	Description
Embedding__Enabled	false	Set to true to enable vector embedding generation
Embedding__Provider	Ollama	Ollama (/api/embed) or OpenAI (/v1/embeddings — vLLM, Text-Embeddings-Inference, or OpenAI)
Embedding__BaseUrl	—	Embedding endpoint (e.g., http://localhost:11434)
Embedding__ModelName	—	Model name (e.g., qwen3-embedding:0.6b)
Embedding__ApiKey	—	Bearer token, if the server requires one (e.g. vLLM --api-key)
Embedding__BatchSize	10	Texts per embedding batch

Update notifications (optional):

Setting	Default	Description
CHECK_FOR_UPDATES	true	When true, the web portal checks GitHub Releases and shows a banner when a newer version is available. Set to false to disable.

Authentication (optional):

Setting	Default	Description
AUTH_USERNAME	—	Web portal username (auth disabled if empty)
AUTH_PASSWORD	—	Web portal password (auth disabled if empty)
MCP_API_KEY	—	MCP server API key (auth disabled if empty)

When set, the web portal requires login and the MCP server requires Authorization: Bearer <key> header. When unset, everything is open access (default).

Updating

The web portal checks GitHub Releases on a schedule and shows a banner when a newer version is available (disable with CHECK_FOR_UPDATES=false). To update to the latest release:

Docker Compose:

git pull
docker compose up -d --build --remove-orphans

Include any optional Compose override files in the upgrade command so those services remain enabled.

From source:

git pull
dotnet build Equibles.sln

Database migrations are applied automatically on startup. Review the changelog for notable changes before upgrading.

Web Portal

The web portal at http://localhost:8080 provides a browser-based interface for exploring data:

Vector Embeddings (advanced, opt-in)

Vector embeddings enable semantic search over SEC filings (e.g., "find revenue growth discussion in Apple's 10-K"). This requires downloading the Ollama runtime (~2GB) and the Qwen3-Embedding-0.6B model (~640MB).

docker compose -f docker-compose.yml -f docker-compose.embedding.yml up

This adds Ollama and configures the existing web, MCP, and worker services to use it:

Service	Port	Description
embedding	11434	Ollama server with Qwen3-Embedding-0.6B model
embedding-pull	—	One-shot model download before the worker starts
worker	—	The existing worker, with embedding generation enabled

Without the embedding override, BM25 full-text search via ParadeDB still works out of the box — vector search is purely additive.

Bundled Ollama is the default because it needs no GPU and runs anywhere. For bulk embedding at scale, point Embedding__Provider=OpenAI at a batched server such as vLLM or Text-Embeddings-Inference — they continuously batch on the GPU and are far faster than Ollama for large corpora. See docs/guide/how-to-use-external-embedding-endpoint.md.
