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.
AI agents call get_glucose_stats to retrieve information from LibreLink MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only analysis on glucose data that has already been stored in the user's LibreLink account. It computes statistics (average glucose, GMI, time-in-range percentages, variability metrics) from historical readings without creating, modifying, or deleting any data. The output is informational analysis for diabetes management insights.
From the tool's definition Tool name is 'get_glucose_stats' and description states it 'Calculate[s] comprehensive glucose statistics' from existing data. No modification, deletion, or external action is implied. It retrieves and analyzes stored glucose readings to produce metrics.

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. It is categorised as a Read tool in the LibreLink MCP Server MCP Server, which means it retrieves data without modifying state.
Register the LibreLink MCP Server MCP server in PolicyLayer and add a rule for get_glucose_stats: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches LibreLink MCP Server. Nothing to install.
get_glucose_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_glucose_stats rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_glucose_stats. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_glucose_stats is provided by the LibreLink MCP Server MCP server (sedoglia/librelink-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
