# PromptHub — how to use (mcp.ai)

Connect your PromptHub account and use 4 tools for artificial intelligence straight from your AI agent. Connect with your own API key. PromptHub provides versioned prompt management, retrieval, and execution through its API.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_prompt_hub?ms=1787291400000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `prompt_hub_get_current_team`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/prompt_hub`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/prompt_hub/_endpoints`

### Endpoints
- `POST https://api.mcp.ai/api/prompt_hub/get/current/team` — Return the current PromptHub team ID for the connected account. Use it when a team-scoped operation must target an explicit team.
