Get sleep skin temperature data from Elixir biosensing. Measures skin temperature during sleep for recovery insights.
AI agents call get_skin_temperature to retrieve information from Polar 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 historical biometric data (skin temperature during sleep) from the Polar fitness platform. It performs a read-only query operation with no ability to modify, delete, or execute actions. The data retrieved is personal health information but access is already gated by Polar's authentication.
From the tool's definition Tool name begins with 'get_', description states 'Get sleep skin temperature data' - purely retrieval operation with 'no side effects' characteristic of Read category. Measures and retrieves historical health metrics.

Get sleep skin temperature data from Elixir biosensing. Measures skin temperature during sleep for recovery insights. It is categorised as a Read tool in the Polar MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Polar MCP Server MCP server in PolicyLayer and add a rule for get_skin_temperature: 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 Polar MCP Server. Nothing to install.
get_skin_temperature 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_skin_temperature 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_skin_temperature. 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_skin_temperature is provided by the Polar MCP Server MCP server (nelsonnew/polar-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
