Once you've [connected a client](/docs/mcp), your agent can call any of these tools by name — you don't invoke them yourself, the model picks the right tool for the question. Each returns structured, sourced data, and every call counts against your [daily limit](/docs/rate-limits). The same data is available over the [REST API](/docs/api/endpoints).

The tools are split into eleven families. Each family page lists its tools with the parameters they take, an example prompt, and a **real, trimmed sample** of what they return (mostly for NVIDIA, ticker `NVDA`) so you can see the shape of the data before wiring anything up.

## Tool families

- [Filings & documents](/docs/mcp/tools/filings) — search, list, and read SEC filings and transcripts; fails-to-deliver; Form D.
- [Fundamentals & valuation](/docs/mcp/tools/fundamentals) — XBRL statements and facts, revenue breakdowns, KPIs, the non-GAAP bridge, guidance, and valuation multiples.
- [Earnings calls & investor relations](/docs/mcp/tools/earnings) — earnings-call briefs and insights, call events and speakers, and IR events and news.
- [Institutional holdings (13F)](/docs/mcp/tools/holdings) — top holders, ownership history, buyers/sellers, institution portfolios, and super-investors.
- [Funds & advisers](/docs/mcp/tools/funds) — registered funds and ETFs (NPORT / N-CEN), fund overlap and consensus, and Form ADV advisers.
- [Insider trading](/docs/mcp/tools/insider) — Form 3/4 transactions, ownership, Form 144 proposed sales, and insider-sentiment scores.
- [Congressional trading](/docs/mcp/tools/congress) — trades by ticker or member, member net-worth, and market-wide aggregates.
- [Short selling](/docs/mcp/tools/short) — short volume, short interest, off-exchange volume, and composite squeeze scores.
- [Capital, executives & screening](/docs/mcp/tools/capital) — buybacks and ATM programs, executive changes and pay, the stock screener, government contracts, and FDA catalysts.
- [Prices & technicals](/docs/mcp/tools/prices) — daily OHLCV, latest prices, and technical indicators.
- [Economic, futures & sentiment](/docs/mcp/tools/economic) — FRED series and calendar, market status, CFTC positioning, and CBOE put/call and VIX.

## Conventions

- **Tickers** are US-listed symbols (e.g. `NVDA`, `AAPL`). Company-scoped tools take a `ticker`.
- **Dates** are `YYYY-MM-DD`. Where a tool accepts a date it defaults to the latest available.
- **Result size** — list tools take `maxResults` (each documents its default); the server caps large lists.
- **Sourcing** — every figure is drawn from SEC filings, exchange data, or the company's own disclosures; nothing is estimated. See [Data methodology](/docs/methodology).
