Overview

AI-generated overview

Remote MCP server giving assistants live gold, silver, platinum and palladium spot prices by karat and currency, plus jewelry melt value and exact gold unit…

What you can do
  • Look up today's gold price per gram, troy ounce, tola and kilogram for 24K down to 9K in about 160 currencies, with spot timestamp and FX date
  • Fetch live spot prices for gold, silver, platinum and palladium per ounce, gram and kilogram, with per-metal errors reported instead of failing
  • Estimate the melt value of a gold item from weight, unit and karat, optionally with a dealer spread to suggest a buyer offer
  • Convert gold weights between gram, kilogram, troy ounce, pennyweight, grain, avoirdupois ounce, tola, Thai baht, Vietnamese chi and luong, Hong Kong and Taiwan tael, and China liang
When to use it
Useful when someone asks for a current gold or precious-metal price, a karat-based price in a specific currency, the scrap or melt value of a piece of jewelry, or a conversion between regional gold weight units that a model cannot know from training data.
Requirements
A remote Streamable HTTP endpoint; no API key, token or sign-up is needed. An optional local stdio version runs via npx and needs Node 20 or newer. Network access to the hosted server, which in turn reads gold-api.com spot prices and Frankfurter FX rates.
Before you install
Prices are spot (melt) values only: retail jewelry costs more and buyers pay less, and the tools state this. Hosted spot prices can be up to 5 minutes old and FX rates are daily reference rates, not live quotes. Karat purity uses the nominal karat/24 fraction, and regional tael values differ, so the intended unit must be chosen. When a feed is down the tool returns an error rather than a stale number.

Installation

In SourceWeft

  1. Open Gold Price Per Gram MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.theluckystrike%2Fgold-price-per-gram-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

README

gold-price-per-gram-mcp

The live gold price per gram for AI assistants, by karat and currency, with metal prices, jewelry melt value and exact gold unit conversion.

This is a Model Context Protocol (MCP) server. It reads the gold, silver, platinum and palladium spot price at call time and converts it with central-bank FX rates for about 160 currencies. It needs no API key.

Tools

ToolWhat it returns
get_gold_price_per_gramGold price per gram, troy ounce, tola and kilogram for 24K, 22K, 21K, 18K, 14K, 10K and 9K in any currency, with the spot time stamp and FX date.
get_metal_pricesSpot price of gold, silver, platinum and palladium per troy ounce, gram and kilogram in any currency. A metal whose feed is down is reported, not fatal.
calculate_jewelry_valueMelt value of a gold item from weight, unit and karat, with an optional dealer spread percent. States that retail and buyback prices differ from melt value.
convert_gold_unitsExact conversion between gram, kilogram, troy ounce, pennyweight, grain, avoirdupois ounce, tola, Thai baht, Vietnamese chi and luong, Hong Kong tael, Taiwan tael and China liang, with the definition and source of each unit.

Every result has structured JSON, a one-paragraph summary, as_of, source and more (the matching page on goldgramprice.com).

What it knows that your model does not

  • Today's gold price. Spot moves every minute and a model's training data is months old.
  • Today's exchange rate for INR, AED, SAR, PKR, EUR, GBP and about 150 more currencies.
  • Exact unit constants. A troy ounce is 31.1034768 g and a grain is 64.79891 mg by definition (NIST Handbook 44). A tola is 180 grains. A Thai bullion baht is 15.244 g, not 15 g. A kitchen-scale ounce is 28.349523125 g, not a troy ounce.
  • Karat purity as an exact fraction (karat / 24), so 22K is 91.6667% and 14K is 58.3333%.

Example prompts

  • "What is the 22K gold price per gram in India today?"
  • "How much is one tola of 24K gold in Pakistani rupees?"
  • "I have a 14K chain that weighs 12 grams. What is its melt value, and what might a buyer offer at a 25% spread?"
  • "Show gold, silver and platinum prices in euros."
  • "How many grams are in a Thai baht of gold, and in a Vietnamese chi?"

Data sources

All keyless and free to use from a server. Full list with fetch dates in DATA_SOURCES.md.

  • Spot prices from gold-api.com, the same feed goldgramprice.com uses. Its terms allow commercial use and ask callers not to send several requests per second, so the hosted server caches each price for 5 minutes.
  • FX rates from Frankfurter, blended from the ECB and other central banks. Cached for 1 hour. Rates update once a working day.
  • Unit constants from NIST Handbook 44 Appendix C. Karat definition from 16 CFR 23.3.

Limitations

  • Prices are spot (melt) values for pure metal. Jewellery in a shop costs more (making charges, design, tax) and buyers pay less (refining and margin). The tools say so in every answer.
  • The spot price can be up to 5 minutes old on the hosted server. FX rates are daily reference rates, not live market quotes.
  • Purity uses the nominal karat fraction. Real items can be slightly under (legal tolerances) or over.
  • Regional tael values differ (Hong Kong 37.429 g, Vietnam 37.5 g, Taiwan 37.5 g, China 50 g). Pick the one you mean.
  • When a price feed is down, the tool returns a clear error instead of a stale or remembered number.

Live spot prices of gold (XAU), silver (XAG), platinum (XPT) and palladium (XPD) per troy ounce, per gram and per kilogram, in any major currency. A metal whose feed is down is reported with its error instead of failing the whole call.

Parameterscurrency

calculate_jewelry_value

Calculate gold jewelry melt value

Melt value of a gold item (ring, chain, bracelet, scrap) from its weight, unit and karat at the live spot price, in any currency. Optional dealer_spread_percent returns the likely buyer offer. The result states that melt value is not the retail or buyback price.

Parametersunitkaratrequiredweightrequiredcurrencydealer_spread_percent

convert_gold_units

Convert gold weight units

Convert a gold weight between gram, kilogram, troy ounce, pennyweight, grain, avoirdupois ounce, tola, Thai baht (bullion and jewellery), Vietnamese chi and luong, Hong Kong gold tael, Taiwan tael and China liang.
