## What it does

This stdio bridge links coding clients to the XCREENER market scanning API. It registers four tools: `xql_validate` to parse queries without touching real data, `xql_explain` to inspect the plan, `xql_run` to fetch matching tickers from live feeds, and `xql_nl_reference`. The assistant reads the reference tool to turn conversational trading prompts into valid XQL queries.

Running any query requires an API key in the `XCREENER_API_KEY` variable from `xcreener.com/account/api-key`. Verification happens lazily: the process will start up cleanly even with an empty key, then throw an `auth` error as soon as you trigger an actual screen.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `XCREENER_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- filter oversold or overbought assets across multiple asset classes simultaneously
- rank currency strength across forex pairs without manual calculations
