The tools

The set

11 tools, 10 on the free tier and 1 on Pro. Every name below links to that tool's own page: what it answers, every argument, every response field, the errors it can return instead of data, and the same worked call over both transports.

The MCP server and the REST API expose the same set from the same registry, so a tool that exists here exists on both with the same arguments and the same answers.

One company at a time

Resolve a name to a covered symbol, then pull its profile, its six scores and the readings behind them. Where most sessions start.

Screening and back-testing

Filter the whole scored universe on your own criteria, find out what a criterion means before you filter on it, and run the same screen back through every year of stored history.

The filings themselves

The company's own annual report, not a summary of it: what sections exist, the full text of one of them, a phrase search across the whole thing, and the notes that bear on a particular score.

Getting a key

1. 1.Register free — an email address, no card — then create a key under API Keys on your account page. Your email address has to be verified first, and the key is shown once.
2. 2.Chat client that speaks MCP? The MCP guide is one paste. Everything else takes bearer auth, the error codes and the limits from the REST guide.
3. 3.Open the page for the tool you want and copy the call.

Free accounts get 12 agent calls per 16 hours — its own allowance, separate from the website's screening actions — and Pro is uncounted. There is no anonymous tier: tools/list and /openapi.json answer without a key because they describe the interface, and nothing that returns data does.
