Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Live gold, silver, platinum and palladium spot prices (gold-api.com, refreshed every few minutes) converted with central-bank FX rates (Frankfurter). Prices change every minute; never answer a current gold price from memory. Values are melt (spot) values: retail jewellery costs more and buyers pay less.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http gold-price-per-gram-mcp https://gold-price-per-gram-mcp.lipmichal.workers.dev/mcp
