Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_current_glucoseA | Get the most recent glucose reading from your FreeStyle Libre sensor. Returns current glucose value in mg/dL, trend direction (rising/falling/stable), and whether the value is in target range. Use this for real-time glucose monitoring. |
| get_glucose_historyA | Retrieve historical glucose readings for analysis. Returns an array of timestamped glucose values. Useful for reviewing past glucose levels, identifying patterns, or checking overnight values. Default retrieves 24 hours of data. |
| get_glucose_statsA | Calculate comprehensive glucose statistics including average glucose, GMI (estimated A1C), time-in-range percentages, and variability metrics. Essential for diabetes management insights and identifying areas for improvement. |
| get_glucose_trends | Analyze glucose patterns including dawn phenomenon (early morning rise), meal responses, and overnight stability. Helps identify recurring patterns that may need attention or treatment adjustments. |
| get_sensor_info | Get information about your active FreeStyle Libre sensor including serial number, activation date, and status. Use this to check if sensor is working properly or needs replacement. |
| configure_credentialsA | Set up or update your LibreLinkUp account credentials for data access. Required before using any glucose reading tools. Credentials are stored securely using AES-256-GCM encryption with keys in your OS keychain. |
| configure_rangesA | Customize your target glucose range for personalized time-in-range calculations. Standard range is 70-180 mg/dL, but your healthcare provider may recommend different targets. |
| validate_connection | Test the connection to LibreLinkUp servers and verify your credentials are working. Use this if you encounter errors or after updating credentials. |
| get_session_status | Get the current authentication session status including whether authenticated, token validity, and expiration time. |
| clear_sessionA | Clear the current authentication session and stored tokens. Use this if you need to force a re-authentication. |

Scored across 6 tools
Each tool has a distinct purpose: current reading, history, stats, credentials, session, and range configuration. No overlap in functionality, and descriptions clearly differentiate them.
All tool names follow a consistent verb_noun pattern in snake_case (e.g., get_current_glucose, configure_credentials). This uniformity aids agent prediction and selection.
Six tools is an appropriate number for a glucose monitoring server, covering essential data retrieval and configuration without being excessive or insufficient.
The set covers core functionalities: current/historical data, statistics, credential setup, and range configuration. Minor gaps exist (e.g., sensor status), but overall it handles typical use cases well.
