AI agents call oura_api_list_paths to retrieve information from Oura Ring without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available API endpoints (GET operations only). It performs pure discovery/enumeration with no side effects, data modification, code execution, or financial impact. The lowest-severity classification applies.
From the tool's definition Tool name includes 'list_paths' and description states 'List all available Oura API v2 GET endpoints' — explicitly a listing/discovery operation with no data modification or execution capability.
Attacks that exploit this kind of access
List all available Oura API v2 GET endpoints with summaries. It is categorised as a Read tool in the Oura Ring MCP Server, which means it retrieves data without modifying state.
Register the Oura Ring MCP server in PolicyLayer and add a rule for oura_api_list_paths: 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. Nothing to install.
oura_api_list_paths 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 oura_api_list_paths 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 oura_api_list_paths. 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.
oura_api_list_paths is provided by the Oura Ring MCP server (@yasuakiomokawa/oura-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
