Moissanite Tools is a Model Context Protocol (MCP) server: FITINY jewellery tools: density-corrected carat/mm, GIA grades, ISO 8653 ring sizes. In practice that means any MCP-compatible AI assistant can call Moissanite Tools's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://mcp.fitiny.com/mcp and you're connected, with nothing to install locally. The current release is v1.0.0, published under the MIT license, with source at FITINY/moissanite-tools on GitHub.
Moissanite Tools is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
