Equibles

What it is

Equibles is a financial-data MCP server that holds its own data. Run docker compose up and a worker starts scraping SEC EDGAR filings and XBRL facts, 13F holdings, insider Forms 3/4/5 and 144, congressional disclosures, FINRA short volume, SEC fails-to-deliver, FRED series, CFTC Commitments of Traders, CBOE VIX and put/call ratios, USAspending contracts, the FDA advisory calendar and daily Yahoo OHLCV into a local Postgres. Sixty-two MCP tools then serve that database to Claude, ChatGPT, Cursor or anything else that speaks MCP, with no account and no key.

Most financial MCP servers wrap somebody's REST API and stop working the day your key lapses. This one ingests, so the rate limit is your hardware and the only keys involved are free ones from FINRA and the St. Louis Fed.

Pricing

Self-hosting costs nothing and is capped by nothing. The money is in the hosted server, which runs the same core plus data the project cannot produce locally. Free is $0 for 100 requests a day across MCP and REST, end-of-day only — intraday, live and option-chain calls return an upgrade link. Plus is $9.99/month for 10,000 requests a day and 15-minute delayed prices. Pro is $49.99/month, $19.99 for a first month, and adds real-time quotes and option chains, CSV export of advanced screens and distribution rights at 100,000 requests a day. The simple screener already exports CSV on the free tier. No annual billing, and requests pause at the cap rather than billing overage.

Data & coverage

US filings and agency feeds only. Backfill starts at January 2020 by default and can be pushed to 2000 or narrowed to a ticker list. Prices are end-of-day Yahoo OHLCV refreshed once every 24 hours; 13F holdings carry the statutory 45-day lag. Plan for 5 GB of disk and 2 GB of RAM to start, 10 GB and 4 GB as history accumulates, and an hour or two before the first sync stops looking sparse.

Integrations

MCP over HTTP for Claude Desktop, Claude Code, ChatGPT and Cursor; the hosted side adds a REST API and OAuth, so those clients connect without a key. Tools return markdown tables by default, or Graph Compact Format behind a header for clients paying by the token.

Limitations

• Real-time quotes, option chains, earnings-call transcripts, guidance and the full-market screener are hosted-only. The self-hosted build is end-of-day, and the docs say outright it is not for live trading.
• "Real-time" on the Pro plan is worth pinning down before you buy. The pricing page sells it that way, but the vendor's own July 2026 comparison post says the self-serve plans' quotes "ride the IEX feed rather than full SIP" and that its chains lag 15 minutes, with real-time chains and top-of-book sold to desks through sales. The two pages disagree; ask which you get.
• The only backtest is cloning a 13F filer's portfolio against a benchmark — no strategy backtester, no order model, no broker.
• You own the scrapers. Nothing is backfilled for you and a broken source is your morning.
• AGPL-3.0, with a contributor agreement that lets the company relicense what you send it.

Alternatives

Vendor-run MCP servers from the data providers themselves — Massive, Financial Modeling Prep, Alpha Vantage — need a key with that vendor but nothing to run. Equibles is the trade in the other direction: hardware and sync time instead of a subscription, filings rather than ticks.
