Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

goldback

get_goldback_rate

The latest Goldback premium multiple over its gold content, and the exchange rate that follows from it.

observed

get_observed_premiums

Rolling fine-metal-weighted median asking premiums for silver, gold, platinum, palladium, copper, nickel and Goldback, observed from marketplace listings. Goldbacks use the Goldback reference rate instead of contained-gold spot and are excluded from ordinary gold statistics.

price

get_price_history

Daily historical series for charting — one metal, the Goldback, or one PCGS-numbered coin at one grade.

spot

get_spot_prices

Current and previous-session spot prices for gold, silver, platinum, palladium, copper and nickel, in any supported currency and per troy ounce or gram.

supported

list_supported_currencies

The live list of codes every `currency`/`base` parameter accepts — ISO 4217 fiat plus BTC and the metal codes.

StackerScan — questions

Answers built from our own checks of this server.

What can StackerScan do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_goldback_rate, get_observed_premiums, get_price_history, get_spot_prices, list_supported_currencies. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is StackerScan working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 22 of 91 checks got a reply (24.2%), average response time 756 ms. The bar chart above shows every period we have measured.

The registry lists StackerScan as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect StackerScan?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does StackerScan need an API key?

No. StackerScan completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is StackerScan?

It answers our handshake in 756 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
