Get glucose statistics including distribution (hypo/low/normal/high/hyper), average, min/max values, and estimated HbA1c for a specified period.
AI agents call get_glucose_statistics to retrieve information from Diabetes:M MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries historical glucose data and computes derived metrics (statistics, averages, HbA1c estimates) without creating, modifying, or destroying any records. It exhibits only read-side effects typical of health data analytics. The broader server context (Diabetes:M health data integration) poses no elevation of risk—a statistical summary is purely informational.
From the tool's definition Tool retrieves glucose statistics including distribution, average, min/max values, and estimated HbA1c—pure data retrieval with 'Get' prefix and no modification, deletion, or execution semantics.
Attacks that exploit this kind of access
Get glucose statistics including distribution (hypo/low/normal/high/hyper), average, min/max values, and estimated HbA1c for a specified period. It is categorised as a Read tool in the Diabetes:M MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Diabetes:M MCP Server MCP server in PolicyLayer and add a rule for get_glucose_statistics: 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 Diabetes:M MCP Server. Nothing to install.
get_glucose_statistics 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_statistics 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_statistics. 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_statistics is provided by the Diabetes:M MCP Server MCP server (sedoglia/diabetes-m-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
