Query sleep sessions for a date range
AI agents call query_sleep to retrieve information from Zepp Life MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical sleep data within a specified date range. It performs a read-only query operation on personal health data. While sleep data is sensitive personal information, the tool itself has no capability to modify, delete, or execute external actions. The impact of misuse is limited to unauthorized visibility of health information rather than system compromise or data loss.
From the tool's definition Tool name is 'query_sleep' and description states 'Query sleep sessions for a date range' — this is a retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
Query sleep sessions for a date range. It is categorised as a Read tool in the Zepp Life MCP MCP Server, which means it retrieves data without modifying state.
Register the Zepp Life MCP server in PolicyLayer and add a rule for query_sleep: 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 Zepp Life MCP. Nothing to install.
query_sleep 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 query_sleep 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 query_sleep. 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.
query_sleep is provided by the Zepp Life MCP server (kubulashvili/zepp-life-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
