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

calculate

calculate_coin_melt

Calculate the melt value of junk silver coins (constitutional silver) at the current silver spot price: US 90% pre-1965 dimes/quarters/halves/dollars, US 40% Kennedy halves (1965–1970), US 35% war nickels (1942–1945), Canadian 80% (1920–1966/67) and Canadian 50% (1967–68) coins. Provide the coin type plus either a quantity of coins or a total face value (e.g. face_value 2.50 for a roll of dimes). Returns total actual silver weight (ASW) in troy oz and grams, and melt value in USD and CAD.

calculate_melt_value

Calculate the melt value (intrinsic bullion value) of silver or gold from weight and purity — e.g. sterling silver flatware, .999 rounds, scrap gold. Returns melt value in both USD and CAD plus the fine metal weight. Purity is a fraction: 0.925 = sterling, 0.999 = fine silver, 0.9 = US coin silver. Weight units: g (grams), ozt (troy ounces), oz (avoirdupois ounces — postal-scale ounces).

spot

get_spot_price

Get the current spot price of silver and gold in USD and CAD per troy ounce. Use this to answer questions about the silver spot price, gold spot price, or the USD→CAD exchange rate used for melt value calculations. Prices are live, cached up to 15 minutes. All prices are per troy ounce (ozt).

80% Silver Melt Calculator — questions

Answers built from our own checks of this server.

What can 80% Silver Melt Calculator do?

It exposes 3 tools, read directly from the server on our last check. Among them: calculate_coin_melt, calculate_melt_value, get_spot_price. 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 80% Silver Melt Calculator working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 85 of 92 checks got a reply (92.4%), average response time 1421 ms. The bar chart above shows every period we have measured.

How do I connect 80% Silver Melt Calculator?

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 80% Silver Melt Calculator need an API key?

No. 80% Silver Melt Calculator completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is 80% Silver Melt Calculator?

It answers our handshake in 1421 ms on average, which is faster than 3% 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.
