Get WHOOP sleep data with optional date range and limit
AI agents call get_whoop_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 sleep data from the WHOOP fitness platform. It performs a query operation with optional filtering parameters (date range, limit) but does not create, modify, delete, or execute external operations. The sibling tools (all get_* and clear_* functions) confirm this is part of a read-centric data access interface. No side effects or data mutations are possible.
From the tool's definition Tool name is 'get_whoop_sleep' and description states 'Get WHOOP sleep data with optional date range and limit' — uses 'Get' verb indicating data retrieval with no modification capability.

PolicyLayer is an MCP gateway — it sits between your AI agents and WHOOP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_whoop_sleep:
{
"version": "1",
"default": "deny",
"tools": {
"get_whoop_sleep": {}
}
}get_whoop_sleep is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get WHOOP sleep data with optional date range and limit. 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_whoop_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_whoop_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_whoop_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_whoop_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_whoop_sleep is provided by the WHOOP MCP Server MCP server (romanevstigneev/whoop-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from WHOOP MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
