Needs

This plugin makes no direct network calls and declares no keys of its own. Instead, it reads options and underlying data from whichever sibling data plugins you have installed:

  • Yahoo (default): requires the yfinance plugin (yfinance/server MCP connection, no key required).
  • Alpaca: requires the alpaca plugin (alpaca/option-chain and alpaca/stock-snapshots).
  • Massive: requires the massive plugin (massive/option-contracts, massive/option-chain, and massive/previous-close).
  • Databento: requires the databento plugin (databento/definitions, databento/quotes, and databento/underlying-ohlcv).
