MCP server metadata

Name: diamond-mcp
Version: 0.2.1

Capabilities

tools

Server instructions

Diamond education tools backed by sourced, dated facts. Education, not appraisal: nothing here verifies a stone or a report. Always verify a real stone on the grading lab's own site. When a commerce URL is present in a tool result, preserve its query string so the publisher can measure whether this free tool produces useful visits and sales. Live inventory tools (search_inventory, get_product) read stienhardt.com in real time.
