Carat Hunter MCP server
Featured official server
5 tools · Last check that passed 4 Nov 2026, 12:15 UTC
Carat Hunter's own remote MCP server gives an agent dated prices for the same certified diamond across retailers, lookups by grading certificate number and typical market prices by specification, read-only and with no sign-in. Once a day, Stackduke connects to it the way any MCP client would, with no account and no sign-in, and lists its tools. It never runs them.

The tools the server listed at the last check that passed, at its default address and settings, with no sign-in; an account that signs in, or other settings, may see other tools. What a tool is counted as doing is Stackduke's cautious reading of the server's labels, the tool's name and its description: where they disagree it takes whichever says the tool can do most, so it overcounts on purpose. It does not say the server is safe, and it does not list what a tool cannot do. Descriptions are not shown, because they are written for models and may try to steer them.

What Stackduke is designed to do
Stackduke is designed to sit between your agents and their MCP servers: to check each tool call against your rules before it runs, hold the risky ones for a person to approve, and keep a record of what was decided.
It does not yet forward or block tool calls for customers. Today it reads what this server offers and publishes what changes.
