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

Leituras de glicose do teu sensor LibreLink Up: gráfico, logbook, estatísticas e resumos (apenas leitura). Ligação segura e com o teu consentimento, a tua senha não fica guardada.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_librelink?ms=1781044800000`
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_get_connection`).

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