GemstoneAI for Agents

GemstoneAI is a hosted remote MCP server that lets an AI assistant help someone with a piece of jewelry they own. The assistant can:

  • analyze 1 to 5 photos of the piece and give a preliminary identification, with its alternatives, unknowns and the evidence that would settle them
  • show photographed comparable listings and sales, each labelled as an asking price or a realized sale
  • save the piece to the person's GemstoneAI collection, so it opens in the GemstoneAI app on their phone
https://api.gemstoneaiapp.com/mcp

There is nothing to install or run. Product page: gemstoneaiapp.com/agents.

Connect

Add the URL as a remote (Streamable HTTP) MCP server in any client that supports one. The client discovers sign-in on its own. The person signs in with the email they use in the GemstoneAI app, so the collection is the same; a new email gets a free account. Each new analysis uses a scan from that account's plan, the same as in the app.

Claude Code, as a plugin (adds the server and a jewelry-research skill):

/plugin marketplace add Iveye-Inc/gemstoneai-agents
/plugin install gemstoneai@gemstoneai

Claude Code, server only:

claude mcp add --transport http gemstoneai https://api.gemstoneaiapp.com/mcp

Then run /mcp in Claude Code to sign in.

Other clients (Claude on the web and desktop, ChatGPT developer mode, Cursor, VS Code, MCP Inspector): add a remote MCP server with the URL above and sign in when prompted.

Client support is listed on the product page. A client is marked tested only after the full journey (photo, analysis, comparables, save, reopen in the app) has passed in it.

Tools

Results never carry numeric confidence. Uncertainty comes as alternatives, unknowns and next evidence. When GemstoneAI's own reads disagree about what the stone is, price context is withheld with the reason. When no priced comparables are found, the answer is "none found", never a value of zero.

Protocol and authentication

  • Streamable HTTP, stateless, JSON responses. Initialize-based clients (protocol 2024-11-05 to 2025-11-25) and 2026-07-28 clients are supported.
  • OAuth 2.1 with PKCE (S256). Discovery: /.well-known/oauth-protected-resource/mcp and /.well-known/oauth-authorization-server on api.gemstoneaiapp.com.
  • Clients register with Client ID Metadata Documents or dynamic client registration. Loopback redirects may use any port.
  • Tokens are bound to one person, one client and this server (RFC 8707). Access tokens last an hour; refresh tokens rotate.
  • Scopes: jewelry:analyze and collection:write.

Latency and limits

Shortened. The full README is on GitHub.
