Questions

Before you start

Do I need a Sixtyfour AI account?

For 13 platform tools, no. The other 1 require your own Sixtyfour AI key. All 14 accept your own key, and terra never meters BYOK calls.

What does a call cost?

Each tool on this page shows its rate; the cheapest is $0.024/success. The rate is the provider's own and useterra.app adds no markup; it is billed per call from a prepaid balance. It is not Sixtyfour AI's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Sixtyfour AI to Claude Code?

Run: claude mcp add --transport http terra https://useterra.app/mcp. One MCP server carries Sixtyfour AI 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 Sixtyfour AI MCP server?

No. useterra.app serves Sixtyfour AI'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 Sixtyfour AI channels are linked above.
