# LibreLink Up B2B (CGM clínica) — how to use (mcp.ai)

Para equipas que acompanham vários pacientes (clínica, familiar): lista os pacientes com partilha ativa e lê glicemia, gráfico, logbook e estatísticas (apenas leitura). Credenciais encriptadas no servidor; ligação segura.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_librelink_business?ms=1781045700000`
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. `librelink_business_get_current_glucose`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/librelink_business`
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/librelink_business/_endpoints`
