Common questions

Is FreeStyle Libre (LibreLinkUp) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: LIBRELINKUP_EMAIL, LIBRELINKUP_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 42 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv), Docker on your computer.

What can I use instead?

freestyle-libre-mcp

An MCP server that gives Claude (or any MCP client) read-only access to FreeStyle Libre CGM glucose readings shared through LibreLinkUp. It talks to the LibreLinkUp API with its own small async client (librelinkup_mcp.core); the API behaviour it relies on follows pylibrelinkup.

Tools

Tool	Returns
`list_patients`	People the LibreLinkUp account follows
`get_current_glucose`	Latest reading with trend arrow
`get_glucose_graph`	Readings from about the last 12 hours, oldest first
`get_glucose_logbook`	Logged events from about the last 2 weeks, oldest first

Every reading tool takes an optional patient: a name ("Ann Lee", "ann") or a patient_id from list_patients. It can be omitted when the account follows one person.

Readings include value in the account's unit, value_mg_dl, unit, timestamp (the sensor's local time), timestamp_utc, and is_high/is_low flags. The current reading also has age_minutes, since LibreLinkUp returns the last known value when the sensor or phone is out of range.

Setup

For a step-by-step guide, including account setup and troubleshooting, see the installation guide. Full documentation is at https://freestyle-libre-mcp.readthedocs.io.

You need a LibreLinkUp follower account: invite it from the LibreLink app, accept the invite in the LibreLinkUp app, and accept any terms there before using this server.

git clone https://github.com/osjayaprakash/freestyle-libre-mcp.git && cd freestyle-libre-mcp

uv sync

Variable	Required	Default	Meaning
`LIBRELINKUP_EMAIL`	yes		Follower account email
`LIBRELINKUP_PASSWORD`	yes		Follower account password
`LIBRELINKUP_REGION`	no	`US`	One of `US`, `EU`, `EU2`, `AE`, `AP`, `AU`, `CA`, `DE`, `FR`, `JP`, `LA`, `RU`

If the region is wrong, the first tool call tells you which one to set.

Run from PyPI

No clone needed; uv fetches and runs the published package:

uvx freestyle-libre-mcp

In a client config, use "command": "uvx", "args": ["freestyle-libre-mcp"].

Run with Docker

The server speaks MCP over stdio, so keep -i:

docker run -i --rm \

-e LIBRELINKUP_EMAIL -e LIBRELINKUP_PASSWORD -e LIBRELINKUP_REGION \ ghcr.io/osjayaprakash/freestyle-libre-mcp:latest

In a client config, use "command": "docker" with those arguments, and pass the variables through the client's env block.

Claude Desktop

Add to claude_desktop_config.json:

"mcpServers": { "librelinkup": { "command": "uv", "args": ["--directory", "/absolute/path/to/freestyle-libre-mcp", "run", "freestyle-libre-mcp"], "env": { "LIBRELINKUP_EMAIL": "you@example.com", "LIBRELINKUP_PASSWORD": "your-password", "LIBRELINKUP_REGION": "US" } } } }

Claude Code

claude mcp add librelinkup \

-e LIBRELINKUP_EMAIL=you@example.com \ -e LIBRELINKUP_PASSWORD=your-password \ -e LIBRELINKUP_REGION=US \ -- uv --directory /absolute/path/to/freestyle-libre-mcp run freestyle-libre-mcp

Langfuse tracing (optional)

Each tool call becomes a Langfuse trace, with a child span for the LibreLinkUp API call. Install the extra and set the keys:

uv sync --extra langfuse

In the server command, use run --extra langfuse freestyle-libre-mcp instead of run freestyle-libre-mcp.

Variable	Meaning
`LANGFUSE_PUBLIC_KEY`, `LANGFUSE_SECRET_KEY`	Tracing is on only when both are set
`LANGFUSE_BASE_URL`	Langfuse URL for self-hosted or regional instances (default: Langfuse Cloud)
`LANGFUSE_CAPTURE_DATA`	`true` to include tool inputs, outputs and error messages. Default `false`

Privacy: glucose readings and patient names are health data. By default, traces hold only tool names, timings, patient UUIDs, and error class names. Setting LANGFUSE_CAPTURE_DATA=true sends readings and names to your Langfuse instance; only do that with an instance you trust, such as a self-hosted one.

Development

uv sync

uv run pytest # offline suite uv run pytest -m live # hits the real API; needs LIBRELINKUP_EMAIL/PASSWORD uv run ruff check src tests && uv run ruff format --check src tests
