No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
StackerScan is an open, read-only HTTP API for live and historical precious-metals prices, observed dealer premiums, the Goldback rate, the currency catalog and published shares. The API requires no authentication, no API keys, and no registration. The API is free and unmetered, with no account needed.
Credits are used for AI-assisted entry features like receipt and coin scanning, photo identification, and spreadsheet import. Prices for credits include a free tier with 20 credits, a starter tier at $2.00 for 60 credits, and a pro tier at $8.00 for 300 credits. The API provides spot prices for gold, silver, platinum, palladium, copper, and nickel in any supported currency per troy ounce or gram.
Observed premiums are 30-day rolling medians taken from actual marketplace listings, not quoted retail markups.
