# Surfaces & SDKs

> onlyfanskit exposes one capability set through a hosted REST API, a hosted MCP server, a CLI, and a TypeScript SDK for types and reference.

onlyfanskit is one capability set behind four entry points. They share the
same account model, methods, and error contract. **Everything runs on onlyfanskit
infrastructure** — you connect accounts on the platform and call them with an
API key.

<CardGroup cols={2}>
  <Card title="REST API" icon="server" href="/api-reference/introduction">
    **Default.** Connect an account once, then call any method or stream events
    over HTTP with a bearer key.
  </Card>

  <Card title="Hosted MCP" icon="robot" href="/mcp/hosted">
    The full surface as agent tools. Your API key selects the connected account
    per call.
  </Card>

  <Card title="CLI" icon="terminal" href="/cli/overview">
    Connect accounts and run actions from the terminal using your API key.
  </Card>

  <Card title="TypeScript SDK" icon="code" href="/sdk/overview">
    Typed method reference and shapes. Use with the REST API; not a self-hosted
    runtime you operate.
