Why treg.to

Why call Coresignal through treg.to

Your account, held safely

Connect once; treg.to keeps the credential server-side and injects it per call. No key on any machine.

Price before the call

The provider's own rate, $0.000 markup. How billing works.

Account billing

Calls through your own connection are not metered by treg.

Your own Coresignal key is free

Register it and those calls are never metered. Your key always wins.

Switch by changing a word

Another provider is a different word in the prompt, not a new integration.

One key, the whole catalog

The same token calls AI Ark, Akta by Wokelo, Apollo.io and 3,611 other tools.

Questions

Before you start

Do I need a Coresignal account?

Yes. This is an own-account connection: you sign in to Coresignal once and your agent uses that connection through your treg.to token. Calls on it are never metered.

How do I add Coresignal to Claude Code?

Run: claude mcp add --transport http treg https://treg.sciatafrica.com/mcp. One MCP server carries Coresignal 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 Coresignal MCP server?

No. treg.to serves Coresignal'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 Coresignal channels are linked above.
