Get Whoop sleep data (score, hours, efficiency, respiratory rate).
AI agents call get_sleep to retrieve information from Whoop MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves personal sleep metrics from the Whoop health platform without creating, modifying, deleting, or executing any actions. It is a pure data query operation with no side effects or ability to change system state. The severity is low because inadvertent exposure of sleep data, while private, does not enable further damaging actions through this tool alone.
From the tool's definition Tool name 'get_sleep' and description 'Get Whoop sleep data' indicate data retrieval with no modification. The data retrieved (score, hours, efficiency, respiratory rate) are read-only biometric metrics.
Attacks that exploit this kind of access
Get Whoop sleep data (score, hours, efficiency, respiratory rate). It is categorised as a Read tool in the Whoop MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Whoop MCP Server MCP server in PolicyLayer and add a rule for get_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 Whoop MCP Server. Nothing to install.
get_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 get_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 get_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.
get_sleep is provided by the Whoop MCP Server MCP server (jd1207/whoop-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
