Get a patient
AI agents call get_patient_whoop_physiological_cycle_data to retrieve information from Intelligent Medical Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read operation that retrieves patient physiological cycle data (likely from WHOOP biometric tracking). While it accesses sensitive health information which could be misused if exfiltrated at scale, the tool itself performs no write, execution, destructive, or financial operations.
From the tool's definition Tool name begins with 'get_patient_' indicating retrieval of patient data. Description states 'Get a patient' which suggests querying/retrieving patient information rather than modifying or executing operations.

Register the Intelligent Medical Assistant MCP server in PolicyLayer and add a rule for get_patient_whoop_physiological_cycle_data: 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 Intelligent Medical Assistant. Nothing to install.
get_patient_whoop_physiological_cycle_data 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_patient_whoop_physiological_cycle_data 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.
