Questions

Before you start

Do I need a Hunter account?

No. Eligible tools run on treg.to's key and the call is metered from your team's prepaid balance, priced up front. If your team registers its own Hunter key, that key always wins and those calls are never metered.

What does a call cost?

Each tool on this page shows its rate; the cheapest is $0.00245/result. The rate is the provider's own and treg.to adds no markup; it is billed per call from a prepaid balance. It is not Hunter's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Hunter to Claude Code?

Run: claude mcp add --transport http treg https://treg.to/mcp — one MCP server carries Hunter and the rest of the catalog.

Which frameworks does it work with?

Anything that speaks MCP (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Grok) and anything that can make an HTTP request (LangChain, CrewAI, LlamaIndex, plain code).

Is this the official Hunter MCP server?

No. treg.to serves Hunter's real API through its own metered proxy: the request is the provider's own, the credential is injected server-side, and the answer is relayed verbatim. The official Hunter channels are linked above.
