Get activity data including steps, calories, and activity levels
AI agents call get_activity 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 activity metrics (steps, calories, activity levels) from the user's Oura Ring data without any side effects, modifications, or destructive actions. It is purely informational read access to personal health data. While the data is sensitive personal health information, the tool itself performs only read operations with no capability to modify, delete, or execute external actions.
From the tool's definition Tool name 'get_activity' and description 'Get activity data including steps, calories, and activity levels' indicate data retrieval with no modification. This is a GET operation that retrieves health metrics from the Oura Ring API.
Attacks that exploit this kind of access
Get activity data including steps, calories, and activity levels. 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_activity: 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_activity 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_activity 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_activity. 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_activity 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.
