AI agents call get_readiness_score to retrieve information from Oura 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 readiness score data from the Oura Ring API without creating, modifying, or deleting any data. It has no side effects on the system or user data. While it accesses personal health information, the risk is limited to unauthorized *reading* of existing data rather than modification or destruction.
From the tool's definition Tool name 'get_readiness_score' and description 'Get daily readiness scores' indicate data retrieval with no modification. The verb 'get' and the read-only nature of fetching health metrics confirm this is a query operation.

PolicyLayer is an MCP gateway — it sits between your AI agents and Oura MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_readiness_score:
{
"version": "1",
"default": "deny",
"tools": {
"get_readiness_score": {}
}
}get_readiness_score is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get daily readiness scores. It is categorised as a Read tool in the Oura MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Oura MCP Server MCP server in PolicyLayer and add a rule for get_readiness_score: 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 MCP Server. Nothing to install.
get_readiness_score 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_readiness_score 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_readiness_score. 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_readiness_score is provided by the Oura MCP Server MCP server (meimakes/oura-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Oura MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
