Get heart rate data with timestamps and sources
AI agents call get_heart_rate to retrieve information from Oura Ring 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 health metrics (heart rate data) from the Oura Ring API without any side effects or capability to modify, delete, or execute operations. It is a simple query/fetch operation consistent with other sibling Read tools like get_activity, get_daily_sleep, etc.
From the tool's definition Tool name 'get_heart_rate' and description 'Get heart rate data with timestamps and sources' indicate data retrieval only. No creation, modification, deletion, code execution, or financial operations are described.
Attacks that exploit this kind of access
Get heart rate data with timestamps and sources. It is categorised as a Read tool in the Oura Ring MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Oura Ring MCP Server MCP server in PolicyLayer and add a rule for get_heart_rate: 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 Oura Ring MCP Server. Nothing to install.
get_heart_rate 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_heart_rate 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_heart_rate. 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_heart_rate is provided by the Oura Ring MCP Server MCP server (jameslouie/oura-ring-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
