Get full sleep data with all details Note: This returns detailed sleep data (~50KB). For a compact summary, use get_sleep_summary(). Args: date: Date in YYYY-MM-DD format
AI agents call get_sleep_data to retrieve information from Garmin 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 health/fitness data (sleep data) from Garmin Connect without modifying, deleting, or executing any operations. It is a read-only query. While the data returned is personal health information, the severity is low because retrieval alone poses minimal risk compared to tools that could modify or delete data.
From the tool's definition Tool name is 'get_sleep_data' and description states 'Get full sleep data with all details' — this is a retrieval operation with no side effects. The tool queries and returns existing sleep data for a specified date.
Documented attack patterns abuse exactly the kind of access get_sleep_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_sleep_data:
{
"version": "1",
"default": "deny",
"tools": {
"get_sleep_data": {}
}
}get_sleep_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get full sleep data with all details Note: This returns detailed sleep data (~50KB). For a compact summary, use get_sleep_summary(). Args: date: Date in YYYY-MM-DD format. It is categorised as a Read tool in the Garmin MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Garmin MCP Server MCP server in PolicyLayer and add a rule for get_sleep_data: 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 Garmin MCP Server. Nothing to install.
get_sleep_data 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_data 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_data. 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_data is provided by the Garmin MCP Server MCP server (taxuspt/garmin_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
