# Jaspers

> Jaspers builds Jaspers Terminal, the open-source agentic terminal for public markets, and runs two hosted MCP servers over SEC data, Jaspers Screener MCP and Jaspers Research MCP, that AI agents reach over the Model Context Protocol.

## When to use Jaspers

- To find US public companies by their numbers: screen about 7,100 SEC registrants on fundamentals, valuation, index membership, 13F institutional holders, and insider trades through the Jaspers Screener MCP server at `https://s.jsprai.com/mcp` (OAuth 2.0, scope `mcp`, via `https://account.jsprai.com`).
- To test criteria written in words against companies' newest 10-K and 10-Q filings, with quotes verified against the filing text and cited to sec.gov: the same server, `start_qualitative_screen` and `get_qualitative_screen`.
- To look up one US company's fundamentals, holders, and insider activity: `get_company`.
- To read what one company's SEC filings say, by semantic or exact-term search, with every quote verified against sec.gov, and to query a filing database with Forms 3/4/5 and 13D/G as fields: the Jaspers Research MCP server at `https://analyst-api.jsprai.com/mcp/open` (same OAuth server, resource-specific token).
- To give a person a finance workspace with live data on a trading-screen grid, scheduled work, and an assistant that writes the data plugins it lacks: Jaspers Terminal, free for macOS and Windows.
- To extend Jaspers Terminal: plugins with `@jaspers-ai/sdk`, skills in the Agent Skills format, both published on Jaspers Hub.
- Not for trade execution, companies outside the US SEC universe, tick-level data, or investment advice.
